Dengue and severe dengue

• Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes.
• About half of the world's population is now at risk of dengue with an estimated 100–400 million infections occurring each year.
• Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.
• While many dengue infections are asymptomatic or produce only mild illness, the virus can occasionally cause more severe cases, and even death.
• Prevention and control of dengue depend on vector control. There is no specific treatment for dengue/severe dengue, and early detection and access to proper medical care greatly lower fatality rates of severe dengue.

Dengue (break-bone fever) is a viral infection that spreads from mosquitoes to people. It is more common in tropical and subtropical climates.

Most people who get dengue will not have symptoms. But for those who do, the most common symptoms are high fever, headache, body aches, nausea, and rash. Most will get better in 1–2 weeks. Some people develop severe dengue and need care in a hospital. 

In severe cases, dengue can be fatal.  

You can lower your risk of dengue by avoiding mosquito bites especially during the day.

Dengue is treated with pain medicine as there is no specific treatment currently.

Most people with dengue have mild or no symptoms and will get better in 1–2 weeks. Rarely, dengue can be severe and lead to death.  

If symptoms occur, they usually begin 4–10 days after infection and last for 2–7 days. Symptoms may include:

• high fever (40°C/104°F)
• severe headache
• pain behind the eyes
• muscle and joint pains
• swollen glands
• rash. 

Individuals who are infected for the second time are at greater risk of severe dengue.

Severe dengue symptoms often come after the fever has gone away:

• severe abdominal pain
• persistent vomiting
• rapid breathing
• bleeding gums or nose 
• restlessness
• blood in vomit or stool
• being very thirsty
• pale and cold skin
• feeling weak.

People with these severe symptoms should get care right away. 

After recovery, people who have had dengue may feel tired for several weeks.

Diagnostics and treatment

There is no specific treatment for dengue. The focus is on treating pain symptoms. Most cases of dengue fever can be treated at home with pain medicine.

Acetaminophen (paracetamol) is often used to control pain. Non-steroidal anti-inflammatory drugs like ibuprofen and aspirin are avoided as they can increase the risk of bleeding.

For people with severe dengue, hospitalization is often needed.

Global burden

The incidence of dengue has grown dramatically around the world in recent decades, with cases reported to WHO increasing from 505 430 cases in 2000 to 5.2 million in 2019. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses  (1) . 

The highest number of dengue cases was recorded in 2023, affecting over 80 countries in all regions of WHO. Since the beginning of 2023 ongoing transmission, combined with an unexpected spike in dengue cases, resulted in a historic high of over 6.5 million cases and more than 7300 dengue-related deaths reported.

Several factors are associated with the increasing risk of spread of the dengue epidemic: the changing distribution of the vectors (chiefly  Aedes aegypti and Aedes albopictus mosquitoes), especially in previously dengue naïve countries; the consequences of El Niño phenomena in 2023 and climate change leading to increasing temperatures and high rainfall and humidity; fragile health systems in the midst of the COVID-19 pandemic; and political and financial instabilities in countries facing complex humanitarian crises and high population movements.

One modelling estimate indicates 390 million dengue virus infections per year of which 96 million manifest clinically  (2) . Another study on the prevalence of dengue estimates that 3.9 billion people are at risk of infection with dengue viruses (3).

The disease is now endemic in more than 100 countries in the WHO Regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia and the Western Pacific. The Americas, South-East Asia and Western Pacific regions are the most seriously affected, with Asia representing around 70% of the global disease burden.

Dengue is spreading to new areas in Europe, the Eastern Mediterranean and South America.

The largest number of dengue cases reported was in 2023. The WHO Region of the Americas reported 4.5 million cases, with 2300 deaths. A high number of cases were reported in Asia: Bangladesh (321 000), Malaysia (111 400), Thailand (150 000), and Viet Nam (369 000).

Transmission

Transmission through the mosquito bite

The dengue virus is transmitted to humans through the bites of infected female mosquitoes, primarily the  Aedes aegypti  mosquito. Other species within the Aedes genus can also act as vectors, but their contribution is normally secondary to  Aedes aegypti . However, in 2023, a surge in local transmission of dengue by Aedes albopictus (tiger mosquito) has been seen in Europe.

After feeding on a infected person, the virus replicates in the mosquito midgut before disseminating to secondary tissues, including the salivary glands. The time it takes from ingesting the virus to actual transmission to a new host is termed the extrinsic incubation period (EIP). The EIP takes about 8–12 days when the ambient temperature is between 25–28°C. Variations in the extrinsic incubation period are not only influenced by ambient temperature; several factors such as the magnitude of daily temperature fluctuations, virus genotype, and initial viral concentration   can also alter the time it takes for a mosquito to transmit the virus. Once infectious, the  mosquito can transmit the virus for the rest of its life .

Human-to-mosquito transmission

Mosquitoes can become infected by people who are viremic with the dengue virus. This can be someone who has a symptomatic dengue infection, someone who is yet to have a symptomatic infection (they are pre-symptomatic), and also someone who shows no signs of illness (they are asymptomatic).

Human-to-mosquito transmission can occur up to 2 days before someone shows symptoms of the illness, and up to 2 days after the fever has resolved.

The risk of mosquito infection is positively associated with high viremia and high fever in the patient; conversely, high levels of DENV-specific antibodies are associated with a decreased risk of mosquito infection. Most people are viremic for about 4–5 days, but viremia can last as long as 12 days.

Maternal transmission

The primary mode of transmission of the dengue virus between humans involves mosquito vectors. There is evidence however, of the possibility of maternal transmission (from a pregnant mother to her baby). At the same time, vertical transmission rates appear low, with the risk of vertical transmission seemingly linked to the timing of the dengue infection during the pregnancy. When a mother does have a dengue infection when she is pregnant, babies may suffer from pre-term birth, low birthweight, and fetal distress.

Other transmission modes

Rare cases of transmission via blood products, organ donation and transfusions have been recorded. Similarly, transovarial transmission of the virus within mosquitoes have also been recorded. 

Risk factors

Previous infection with DENV increases the risk of the individual developing severe dengue.

Urbanization (especially unplanned), is associated with dengue transmission through multiple social and environmental factors: population density, human mobility, access to reliable water source, water storage practice etc.

Community risks to dengue also depend on a population’s knowledge, attitude and practice towards dengue, as the exposure is closely related to behaviours such as water storage, plant keeping, and self-protection against mosquito bites.  Routine vector surveillance and control activities engaging community greatly enhances a community’s resilience. 

Vectors might adapt to new environments and climate. The interaction between dengue virus, the host and the environment is dynamic. Consequently, disease risks may change and shift with climate change in tropical and subtropical areas, in combination with increased urbanization and movement of populations.

Prevention and control

The mosquitoes that spread dengue are active during the day. 

Lower the risk of getting dengue by protecting yourself from mosquito bites by using: 

• clothes that cover as much of your body as possible;
• mosquito nets if sleeping during the day, ideally nets sprayed with insect repellent;
• window screens;
• mosquito repellents (containing DEET, Picaridin or IR3535); and
• coils and vaporizers.

Mosquito breeding can be prevented by:

• preventing mosquitoes from accessing egg-laying habitats by environmental management and modification;
• disposing of solid waste properly and removing artificial man-made habitats that can hold water;
• covering, emptying and cleaning domestic water storage containers on a weekly basis;
• applying appropriate insecticides to outdoor water storage containers.

If you get dengue, it’s important to:

• drink plenty of liquids;
• use acetaminophen (paracetamol) for pain;
• avoid non-steroidal anti-inflammatory drugs, like ibuprofen and aspirin; and
• watch for severe symptoms and contact your doctor as soon as possible if you notice any.

So far one vaccine (QDenga) has been approved and licensed in some countries. However, it is recommended only for the age group of 6 to 16 years in high transmission settings. Several additional vaccines are under evaluation.

WHO response

WHO responds to dengue in the following ways:

• supports countries in the confirmation of outbreaks through its collaborating network of laboratories;
• provides technical support and guidance to countries for the effective management of dengue outbreaks;
• supports countries in improving their reporting systems and capture the true burden of the disease;
• provides training on clinical management, diagnosis and vector control at the country and regional level with some of its collaborating centres;
• formulates evidence-based strategies and policies;
• support countries in the development of dengue prevention and control strategies and adopting the Global Vector Control Response (2017–2030) and the Global Arbovirus Initiative (2022–2025).
• reviews and recommends the development of new tools, including insecticide products and application technologies;
• gathers official records of dengue and severe dengue from over 100 Member States; and

In the face of these challenges, Bangladesh has taken significant strides. Government initiatives, healthcare partnerships, and community engagement have collectively contributed to heightened awareness and enhanced vector control measures. However, sustaining these efforts requires continuous vigilance and collaboration on a national scale.

The impact of dengue stretches beyond individuals, influencing families, communities, and the nation’s overall progress. Managing dengue is not just a medical endeavor; it is a collaborative pursuit that necessitates the active involvement of citizens, public health agencies, non-governmental organizations, and policymakers. By fostering a culture of prevention, cleanliness, and awareness, Bangladesh can effectively mitigate the impact of dengue, ensuring a healthier future for its citizens.

Essay on Dengue Fever 300 words

Dengue fever

From Where Starts: Aedes aegypti and Aedes albopictus mosquito , dengue fever is transmitting to humans. It is found in Africa. Then spread out in India, Singapore, Taiwan, Urban, Indonesia, Brazil, Bangladesh, and many other countries. About 40% or 2.5 billion people are affected by dengue fever.

Symptoms: Severe headache and fever is the first symptom. Then pain in muscles, joints, and behind the eye, blood vessels disintegration, skin rash, vomiting, diarrhea, abdominal pain, and gastritis also. Symptoms appear 4 to 7 days after mosquito biting and last from 3 to 10 days.

Treatment: Dengue fever is a virus disease and no vaccine was invented. Only paracetamol and no anti-steroidal medicine to the patient for removing the pain. For releasing dehydration drink clean abundant water.

In Serious Condition: Hospitalize is a must when fever looks like a severe condition. Man cannot take fluid by mouth so give an intravenous fluid supplement. If the patients are affecting as twice then comes it very dangerous condition.

Similar Diseases: Dengue fever, typhoid and malaria fever symptoms are similar. After doctors’ check-up take a blood test for confirmation. Then should maintain doctors’ prescriptions.

Precaution: For recovering prevention is the best. Avoid mosquito bites, cover your body with long pants, long-sleeve shirts, socks, hats,s and try to reduce enclosed skin. Avoid scents and timing for breaking out mosquitoes, stagnant water.

Conclusion: Papaya leaves juice is good for dengue fever. Symptoms may disappear after some days but still cause a hamper to health. Take treatment at the appropriate time for permanently realizing it.

Introduction

Dengue fever is a self-limiting flu-like illness that is caused by the dengue virus (a type of flavivirus).

Dengue fever is typically spread by the mosquito Aedes aegypti which is common in the tropics worldwide, especially Southeast Asia, Africa, the Pacific and the Americas. 1 It is less commonly spread by Aedes albopictus . 2

There are four serotypes of the dengue virus: DEN-1, DEN-2, DEN-3 and DEN-4.

Those who are infected by the dengue virus develop life-long immunity . 2 However, individuals with previous immunity to one serotype infected with another serotype can develop severe dengue. 1

The incubation period of dengue fever is usually two to seven days . There are three phases of dengue fever: febrile phase, critical phase and recovery phase. 1

Risk factors

Risk factors for contracting dengue fever include: 3

• Living or travelling to dengue-endemic areas
• Poor public hygiene
• High population density

Clinical features

The clinical features of dengue fever differ according to the phase of the disease. 

Febrile phase

The febrile phase usually lasts two to seven days.

Typical symptoms of the febrile phase include:

• High-grade fever
• Maculopapular rash
• Facial flushing
• Muscle and joint pains
• Severe headache
• Retro-orbital pain
• Nausea or vomiting

Clinical examination

Typical findings on clinical examination include:

• Maculopapular rash sparing palms and soles (Figure 1)
• Positive tourniquet test: inflate blood pressure cuff on upper arm for five minutes; a positive test is when there is >20 petechiae per 2.5cm. 2

Critical phase

The critical phase usually happens after the third day of fever and lasts for 24 to 48 hours. There is an increase in capillary permeability with a drop in body temperature.

Typical symptoms of the critical phase include:

• Severe abdominal pain
• Persistent vomiting
• Rapid breathing
• Altered consciousness level
• Restlessness

Signs of non-severe dengue include:

• Maculopapular rash sparing palms and soles
• Positive tourniquet test

Important signs to not miss out which may indicate dengue with warning signs include:

• Haemorrhagic manifestations: petechiae, mucosal membrane bleeding and menorrhagia
• Enlarged and tender liver
• Evidence of shock: prolonged capillary refill time

Signs that indicate severe dengue include:

• Clinical fluid accumulation: pleural effusion and ascites
• Periorbital oedema
• Hypovolaemic shock
• Severe bleeding

Recovery phase

During the recovery phase , the leaked plasma is reabsorbed into the bloodstream. The individual generally improves in the following 48 to 72 hours.

Some patients may develop a rash known as “isles of white in a sea of red” which indicates recovery (Figure 2). 3

Classification

The severity of dengue is classified using the WHO Dengue Classification 2009 (Table 1).

Table 1 . The classification of severity for dengue fever.

Differential diagnoses

Possible differential diagnoses in the context of suspected dengue fever include: 3

• Typhoid fever
• HIV seroconversion
• Infectious mononucleosis
• Erythema infectiosum
• Chikungunya

Investigations

Bedside investigations.

Relevant bedside investigations in the context of dengue fever include:

• Blood pressure: hypotension may result from dengue shock syndrome

Laboratory investigations

Relevant laboratory investigations in the context of dengue fever include:

• FBC: raised haematocrit and low platelet count suggests dengue with warning signs (may also present with neutropenia and leukopenia)
• LFTs: raised ALT and AST suggests severe dengue with organ involvement
• U&Es: there may be electrolyte imbalance due to persistent vomiting
• Coagulation screen: may reveal prolonged APTT and PT

Relevant imaging investigations in the context of dengue fever include:

• Chest X-ray: to assess for pleural effusion

Other investigations

Diagnostic tests that may be used to confirm dengue fever include: 3,4

• NS1 antigen test: detected in first 4 days of illness
• IgM antibodies with ELISA: detected after 5 days of illness and peaks 2 weeks after onset of symptoms
• IgG antibodies with ELISA: detected after 7 days of illness and lasts for life (used to confirm secondary infection)

Initial management

Most dengue patients do not need hospital admission and there is no specific treatment for dengue fever.

However, patients must be evaluated for warning signs and the possibility of developing severe dengue. Key points of management include:

• Controlling fever with paracetamol
• Notifying Public Health England
• IV fluid resuscitation with close monitoring to prevent fluid overload
• Escalation of patients with warning signs and severe dengue to a secondary health care facility

Some steps that can be taken to prevent dengue fever especially during travel include: 5

• Wearing long-sleeved clothes
• Spraying insect repellent
• Removing any sources of breeding sites

Complications

Potential complications of dengue fever include: 3

• Dengue haemorrhagic fever
• Disseminated intravascular coagulation
• Dengue shock syndrome
• Severe organ involvement (e.g. cardiac failure, liver impairment)
• Dengue fever is a self-limiting flu-like illness that is caused by the dengue virus .
• Dengue fever has three phases : febrile phase, critical phase and recovery phase.
• The severity of dengue fever can be divided into non-severe dengue , non-severe dengue with warning signs and severe dengue .
• Laboratory investigations including FBC , LFTs and U&Es as well as diagnostic tests for dengue should be carried out if dengue is suspected.
• Dengue is a self-limiting illness and patients are usually admitted if they develop warning signs or severe dengue.
• Complications of developing dengue fever include dengue haemorrhagic fever, dengue shock syndrome, disseminated intravascular coagulation and organ impairment.

Introduction

• Dengue is the most rapidly spreading mosquito-borne viral disease in the world.
• According to the data of the World Health Organisation (WHO), an estimated 50 million dengue infections occur annually and approximately 2.5 billion people live in dengue-endemic countries.
• Dengue inflicts significant health, economic and social burden on the populations of endemic areas.
• Dengue afflicts all levels of society, but the burden may be higher among the poorest who grow up in communities with an inadequate water supply and solid waste infrastructure, and where conditions are most favourable for multiplication of the main vector, Aedes aegypti.

What are the Symptoms of Dengue Fever?

The symptoms include:

• Muscle and joint pains

It takes about two to seven days to fully recover. In extreme cases, the disease can develop into severe dengue, known as dengue hemorrhagic fever that causes bleeding, low levels of blood platelets, and blood plasma leakage.

What Causes Dengue Fever?

• Dengue is spread by several species of female mosquitoes of the Aedes variety, specifically of the Aedes aegypti.
• The ideal conditions for this species of mosquitos are usually between the latitudes of 35° North and 35° South with an elevation of 1000 meters (3300 ft). They usually bite during the early morning and in the evening, though it does not mean that they will specifically bite at these hours.
• Even though humans are the primary host of the virus, non-human primates are also carriers.
• A single bite is more than enough to be a cause for infection.
• A female mosquito that bites a person infected person with dengue becomes infected during the initial 2-10 day febrile period.
• After 8 – 10 days, the virus spreads to other tissues including the mosquitoes salivary glands, and is subsequently released into its saliva. As per the research conducted on this species, the mosquito remains infected.

The image below explains the life-cycle of dengue fever:

What can be done to prevent the spread of Dengue Fever?

The spread of Dengue fever is largely dependent on the control of and protection from the bites of the mosquito that transmits it. The following five elements are the recommendation for an Integrated Vector Control by the World Health Organisation:

• Advocacy, social mobilization, and legislation to ensure that public health bodies and communities are strengthened
• Collaboration between the health and other sectors (public and private);
• An integrated approach to disease control to maximize the use of resources;
• Evidence-based decision-making to ensure any interventions are targeted appropriately; and
• Capacity-building to ensure an adequate response to the local situation.
• The main method of controlling the breeding of Aedes aegypti is by destroying its habitats and breeding grounds the primary method of controlling Aedes aegypti is by eliminating its habitats. This involves eliminating open sources of water. This is done by getting rid of open sources of water, or by adding insecticides or biological control agents to these areas.
• The removal of open collection of water is far more effective and optimal removal of control as the application of insecticides may have adverse negative health effects on the local population, due to the risk they pose in contaminating local food sources.
• People can prevent mosquito bites by wearing clothing that fully covers the skin, using mosquito netting while resting, and/or the application of insect repellent (DEET being the most effective).
• While these measures can be an effective means of reducing an individual’s risk of exposure, they do little in terms of mitigating the frequency of outbreaks, which appear to be on the rise in some areas, probably due to urbanization increasing the habitat of Aedes aegypti .

Frequently Asked Questions Related to Dengue

Dengue: Causes and Prevention

Last updated on November 16, 2022 by ClearIAS Team

Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes. India sees a rise in cases of dengue, especially in rainy seasons. It is one of the most rapidly spreading viral tropical diseases. Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. Read here to know the causes, symptoms, and preventive measures for dengue.

Dengue is a mosquito-borne viral disease that has rapidly spread to all tropical regions .

Dengue virus is transmitted by female mosquitoes mainly of the species  Aedes aegypti  and, to a lesser extent,  Ae. albopictus .

Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

A recent study published in 2022 projected how the distribution of these mosquitoes will evolve with climate change .

• Currently,  Aedes Aegyptus is prevalent in the southern peninsula, eastern coastline, north-eastern states, and the northern plains.
• Aedes albopictus dominates the eastern and western coastlines, north-eastern states, and the lower Himalayas.
• The study projected the expansion of Aedes aegypti in the hot arid regions of the Thar Desert and Aedes albopictus in the cold upper Himalayas as a result of future climatic changes.

The Swahili word Ka-dinga pepo, which translates to “cramp-like seizure,” is where the English word “dengue” originates.

In the 1780s, the first dengue outbreaks to be clinically identified occurred practically concurrently in Asia, Africa, and North America.

Because of the symptoms of myalgia and arthralgia, Benjamin Rush, who popularised the term “break-bone fever,” wrote the first clinical case report of the 1780 pandemic in Philadelphia in 1789.

The term dengue fever came into general use only after 1828.

Causes and symptoms of Dengue

Dengue virus belongs to the family Flaviviridae , having four serotypes that are spread by the bite of infected Aedes mosquitoes.

• There are four dengue virus serotypes and it is possible to be infected four times.
• These mosquitoes are also vectors of chikungunya, yellow fever, and Zika viruses.
• The ideal conditions for this species of mosquitos are usually between the latitudes of 35° North and 35° South with an elevation of 1000 meters (3300 ft).
• They usually bite during the early morning and in the evening, though it does not mean that they will specifically bite at these hours.
• A single bite is more than enough to be a cause for infection.
• A female mosquito that bites an infected person with dengue becomes infected during the initial 2-10-day febrile period.
• After 8-10 days, the virus spreads to other tissues including the mosquito’s salivary glands and is subsequently released into its saliva.

It causes a wide spectrum of illnesses from mild asymptomatic illness to severe fatal dengue hemorrhagic fever/dengue shock syndrome.

Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries. Severe dengue was first recognized in the 1950s during dengue epidemics in the Philippines and Thailand.

There is no specific treatment for dengue/severe dengue. Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%.

Dengue should be suspected when a high fever (40°C/104°F) is accompanied by two of the following symptoms during the febrile phase (2-7 days):

• severe headache
• pain behind the eyes
• muscle and joint pains
• swollen glands

Transmission of the virus

There are several routes of transmission of the dengue virus-

Transmission through the mosquito bite

The virus is transmitted to humans through the bites of infected female mosquitoes, primarily the  Aedes aegypti  mosquito.

• After feeding on a Virus-infected person, the virus replicates in the mosquito midgut, before it disseminates to secondary tissues, including the salivary glands.
• The time it takes from ingesting the virus to actual transmission to a new host is termed the extrinsic incubation period (EIP).
• The EIP takes about 8-12 days when the ambient temperature is between 25-28°C.

Human-to-mosquito transmission

• Mosquitoes can become infected by people who are viraemic with the virus. This can be someone who has a symptomatic dengue infection, someone who is yet to have a symptomatic infection (they are pre-symptomatic), but also people who show no signs of illness as well (they are asymptomatic).
• Human-to-mosquito transmission can occur up to 2 days before someone shows symptoms of the illness, up to 2 days after the fever has resolved.

Maternal transmission

• The primary mode of transmission of Viruses between humans involves mosquito vectors.
• There is evidence, however, of the possibility of maternal transmission (from a pregnant mother to her baby).
• While vertical transmission rates appear low, the risk of vertical transmission is seemingly linked to the timing of the dengue infection during pregnancy.
• When a mother does have a DENV infection when she is pregnant, babies may suffer from pre-term birth, low birth weight, and fetal distress.

Treatment and Vaccination

There is no specific treatment for viral fever. Patients should rest, stay hydrated and seek medical advice.

Supportive care such as fever reducers and painkillers can be taken to control the symptoms of muscle aches and pains, and fever.

The first dengue vaccine, Dengvaxia® (CYD-TDV) developed by Sanofi Pasteur was licensed in December 2015 and has now been approved by regulatory authorities in ~20 countries.

Global burden of dengue

The incidence of dengue has grown dramatically around the world in recent decades. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses.

The total number of cases seemingly decreased during the years 2020 and 2021, as well as for reported deaths. However, the data is not yet complete and the COVID-19 pandemic might have also hampered case reporting in several countries.

Before 1970, only 9 countries had experienced severe dengue epidemics.

• The disease is now endemic in more than 100 countries in the regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia, and the Western Pacific.
• The Americas, South-East Asia, and Western Pacific regions are the most seriously affected, with Asia representing ~70% of the global burden of disease.
• Local transmission was reported for the first time in France and Croatia in 2010 and imported cases were detected in three other European countries.

Prevention and Control of Dengue

The proximity of mosquito vector breeding sites to human habitation is a significant risk factor for dengue.

At present, the main method to control or prevent the transmission of the dengue virus is to combat the mosquito vectors. This is achieved through:

• Prevention of mosquito breeding.
• Personal protection from mosquito bites.
• Educating the community on the risks of mosquito-borne diseases.
• Active mosquito and virus surveillance.
• Vector surveillance can be combined with clinical and environmental surveillance

The integration of vector management approaches is encouraged by the WHO to achieve sustainable, effective locally adapted vector control interventions.

The government of India has a National Centre for Vector Borne diseases under the Ministry of Health, which updates guidelines and preventive measures for numerous vector-borne diseases like dengue, chikungunya, and malaria .

Dengue is an acute viral illness caused by RNA virus of the family Flaviviridae and spread by Aedes mosquitoes. Presenting features may range from asymptomatic fever to dreaded complications such as hemorrhagic fever and shock. A cute-onset high fever, muscle and joint pain, myalgia, cutaneous rash, hemorrhagic episodes, and circulatory shock are the commonly seen symptoms. Oral manifestations are rare in dengue infection; however, some cases may have oral features as the only presenting manifestation. Early and accurate diagnosis is critical to reduce mortality. Although dengue virus infections are usually self-limiting, dengue infection has come up as a public health challenge in the tropical and subtropical nations. This article provide a detailed overview on dengue virus infections, varied clinical manifestations, diagnosis, differential diagnosis, and prevention and treatment.

The dengue virus, a member of the genus Flavivirus of the family Flaviviridae, is an arthropode-borne virus that includes four different serotypes (DEN-1, DEN-2, DEN-3, and DEN-4).[ 1 , 2 ] The World Health Organization (WHO) consider dengue as a major global public health challenge in the tropic and subtropic nations. Dengue has seen a 30-fold upsurge worldwide between 1960 and 2010, due to increased population growth rate, global warming, unplanned urbanization, inefficient mosquito control, frequent air travel, and lack of health care facilities.[ 3 , 4 , 5 ] Two and a half billion people reside in dengue-endemic regions[ 5 ] and roughly 400 million infections occuring per year, with a mortality rate surpassing 5–20% in some areas.[ 6 ] Dengue infection affects more than 100 countries, including Europe and the United States (USA).[ 7 ] The first reported case of dengue like illness in india was in Madras in 1780, the first virologically proved epidemic of DF in India occurred in Calcutta and Eastern Coast of India in 1963-1964.[ 8 ] Dengue virus infection presents with a diverse clinical picture that ranges from asymptomatic illness to DF to the severe illness of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS).[ 4 ] Oral mucosal involvement is seen in approximately 30% of patients, although oral features are more frequently associated with DHF than with DF.[ 9 ] Dengue virus infection exhibit varied clinical presentation, hence, accurate diagnosis is difficult and relies on laboratory confirmation. The condition is usually self-limiting and antiviral therapy is not currently available. Supportive care with analgesics, hydration with fluid replacement, and sufficient bed rest forms the preferred management strategy.

ETIOPATHOGENESIS

DF is a severe flu-like infection that involves individuals of all age groups (infants, children, adolescents, and adults).[ 9 ] Transmission among human beings occurs by the mosquito Aedes aegypti and chiefly occurs during the rainy season.[ 10 ] The proposed etiologies for dengue virus infection are:

• Viral replication, primarily in macrophages[ 11 ]
• Direct skin infection by the virus[ 12 ]
• Immunological and chemical-mediated mechanism induced by host–viral interaction.[ 12 ]

Dengue virus gains entry into the host organism through the skin following an infected mosquito bite. Humoral, cellular, and innate host immune responses are implicated in the progression of the illness and the more severe clinical signs occur following the rapid clearance of the virus from the host organism. Hence, the most severe clinical presentation during the infection course does not correlate with a high viral load.[ 13 ] Alterations in endothelial microvascular permeability and thromboregulatory mechanisms lead to an increased loss of protein and plasma. Proposed theories suggest that endothelial cell activation caused by monocytes, T-cells, the complement system, and various inflammatory molecules mediate plasma leakage. Thrombocytopenia may be related to alterations in megakaryocytopoiesis, manifested by infection of human hematopoietic cells and compromised progenitor cell growth. This may cause platelet dysfunction, damage, or depletion, leading to significant hemorrhages.[ 14 , 15 ]

Figure 1 depicts a diagramatic representation of the pathogenesis of dengue.

Pathogenesis of dengue virus infection

CLASSIFICATION

The WHO classifies DF into two groups: Uncomplicated and severe.[ 16 , 17 ] Severe cases are linked to excessive hemorrhage, organ impairement, or severe plasma escape, and the remaining cases are considered uncomplicated.[ 17 ]

According to the 1997 classification, dengue can be divided into undifferentiated fever, DF, and DHF.[ 18 ] DHF was further subdivided into grades I–IV.

Grade I: Only mild bruising or a positive tourniquet test

Grade II: Spontaneous bleeding into the skin and elsewhere

Grade III: Clinical sign of shock

Grade IV: Severe shock - feeble pulse, and blood pressure cannot be recorded.[ 19 ]

Here, grades III and IV comprise DSS.[ 17 ]

CLINICAL MANIFESTATIONS

Undifferentiated fever.

This stage is seen mostly in the primary infection but may also occur following the initial secondary infection. Clinically, it is difficult to differentiate from numerous other viral diseases and often remains undiagnosed.

Dengue fever

DF follows both primary and secondary infections, and is most frequently encountered in adults and older children. Onset of symptoms is characterized by a biphasic, high-grade fever lasting for 3 days to 1 week.[ 20 , 21 ] Severe headache (mainly retrobulbar), lassitude, myalgia and painful joint, metallic taste, apetite loss, diarrhea, vomiting, and stomachache are the other reported manifestations. Dengue is also known as breakbone fever because of the associated myalgia and pain in joints.[ 16 , 22 ] Of patients with DF, 50–82% report with a peculiar cutaneous rash.[ 23 , 24 ] The initial rash is the result of capillary dilatation, and presents as a transient facial flushing erythema, typically occuring before or during the first 1–2 days of fever. The second rash is seen at 3 days to 1 week following the fever, and presents as a asymptomatic maculopapular or morbilliform eruption. Sometimes, individual lesions may merge and present as widespread confluent erythematous areas with pinpoint bleeding spots and rounded islands of sparing, giving a typical appearance of “white islands in a sea of red.”[ 23 , 25 ] The cutaneous rash is usually asymptomatic, and pruritis is reported only in 16-27% cases.[ 9 , 26 ] Bleeding episodes are infrequently seen in DF, although epistaxis and gingival bleeding, substantial menstruation, petechiae/purpura, and gastrointestinal tract (GIT) hemorrhage can occur.[ 20 , 27 ]

Dengue hemorrhagic fever

DHF is frequently seen during a secondary dengue infection. However, in infants it may also occur durring a primary infection due to maternally attained dengue antibodies.[ 28 ] The proposed diagnostic criteria for DHF includes:[ 29 ]

• a. Clinical parameters: Acute-onset febrile phase – high-grade fever lasting from 2 days to 1 week. Hemorrhagic episodes (at least one of the following forms): Petechiae, purpura, ecchymosis, epistaxis, gingival and mucosal bleeding, GIT or injection site, hematemesis and/or malena

Positive tourniquet and hepatomegaly.

• b. Laboratory parameters: Thrombocytopenia (platelet count <100,000/cu mm)

The hemorrhagic episodes in DHF are associated with multifactorial pathogenesis. Vasculopathy, deficiency and dysfunction of platelets and defects in the blood coagulation pathways are the attributed factors.[ 30 ] Decreased production of platelets[ 31 , 32 ] and increased destruction of platelets may result in thrombocytopenia in DHF.[ 33 ] The impaired platelet function causes the blood vessels to become fragile and this results in hemorrhage.[ 34 ]

The clinical course of DHF is characterized by three phases: Febrile, leakage, and convalescent phase. High-grade fever of acute onset along with constitutional signs and facial erythema characterizes the commencement of the febrile illness.[ 21 ] The initial febrile illness is marked by a morbilliform rash and hemorrhagic tendencies.[ 35 ] The fever persists for 2 days to 1 week and then drops to normal or subnormal levels when the patient either convalesces or advances to the plasma leakage phase.[ 36 ] High plasma escape cases are marked by frank shock with low pulse pressure, cyanosis, hepatomegaly, pleural and pericardial effusions, and ascites. Severe ecchymosis and gastrointestinal bleeding followed by epistaxis may also be noted in a few cases. Bradycardia, confluent petechial rashes, erythema, and pallor are seen during this phase.

Dengue shock syndrome

DSS is defined as DHF accompanied by a unstable pulse, narrow pulse pressure (<20 mmHg), restlessness, cold, clammy skin, and circumoral cyanosis. Progressively worsening shock, multiorgan damage, and disseminated intravascular coagulation account for a high mortality rate associated with DSS. The shock persists for a short span of time and the patient promptly recovers with supportive therapy.[ 37 , 38 ]

OROFACIAL FEATURES

Oral features are infrequently seen in dengue virus infection and are more commonly associated with DHF. Erythema, crusting of lips, and ntongue and soft palatal vesicles constitute the prominent oral features in dengue virus infection. Chadwick et al .[ 26 ] reported higher cases involving the mucosa with scleral injection (90%), whereas Sanford noticed vesicular eruptions of the soft palate (>50%).[ 39 ] Byatnal et al ., reported numerous hemorrhagic bullae on the sublingual mucous membrane, lateral surface of the tongue, and floor of the mouth. Brown-colored plaquelike lesions with a rough surface were seen on the buccal mucosa that showed bleeding on touch along with spontaneous bleeding from the gingiva and the tongue. Petechiae, purpura, ecchymoses, and nasal bleeding have also been reported.[ 40 ] Mitra et al . reported bleeding gums, hemorrhagic plaques, and inflamed tonsils in a dengue-infected patient.[ 41 ] Isolated hypoglossal nerve palsy following dengue infection is a rare occurence.[ 42 ] Taste alteration, conjunctival redness, and lymphadenopathy may also be reported in DF.[ 3 ] Table 1 depicts the reported orofacial features of dengue.

Summary of reported orofacial features in dengue[ 4 ]

Cautious attention should be directed at DF if a patient suffers from high fever within 2 weeks of being in the tropics or subtropics.[ 43 ] A decreased number of white blood cells (leukopenia), accompanied by a decreased number of platelet count (thrombocytopenia) and metabolic acidosis are the initial changes on laboratory examinations. Microbiological laboratory testing confirms the diagnosis of DF. Virus segregation in cell cultures, nucleic acid demonstration by polymerase chain reaction (PCR), and serological detection of viral antigens (such as NS1) or particular antibodies are the preferred microbiological assays.[ 5 ] Viral segregation and nucleic acid demonstration provide precise diagnosis, although the high cost limits the availability of these tests.

DIFFERENTIAL DIAGNOSIS

Broad differential diagnosis is considered in a patient presenting with fever and a rash similar to that seen in DF. Tables ​ Tables2 2 and ​ and3 3 present the varied clinical conditions that mimic the febrile and critical phase of dengue infection.

Conditions that mimic the febrile phase of dengue infection[ 4 ]

Conditions that mimic the critical phase of dengue infection[ 4 ]

MANAGEMENT OF DENGUE INFECTION

Fluid replacement and antipyretic therapy with paracetamol is the preferred therapy following the febrile phase. Care should be taken not to use other nonsteroidal antiinflammatory drugs.

Judicious fluid administration forms the mainstay of treatment during the critical phase of the infection. Normal saline, Ringer's Lactate, and 5% glucose diluted 1:2 or 1:1 in normal saline, plasma, plasma substitutes, or 5% albumin are the routinely administered fluids.

WHO guidelines summarize the following principles of fluid therapy:[ 44 ]

• Oral fluid supplementation must be as plentiful as possible. However, intravenous fluid administration is mandatory in cases of shock, severe vomiting, and prostration (cases where the patient is unable to take fluids orally)
• Crystalloids form the first-line choice of intravenous fluid (0.9% saline)
• Hypotensive states that are unresponsive to boluses of intravenous crystalloids, colloids (e.g., dextran) form the second-line measures
• If the patient remains in the critical phase with low platelet counts, there should be a serious concern for bleeding. Suspected cases of bleeding are best managed by transfusion of fresh whole blood.

DENTAL MANAGEMENT

Oral lesions are infrequently seen and are often misguided as platelet defects.[ 25 ] Significant hemorrhagic manifestations need platelet transfusions. In general, there is no need to give prophylactic platelets even at <20,000/cu mm. Prophylactic platelets may be given at a level of <10,000/cu mm in absence of bleeding manifestations. In case of systemic massive bleeding, platelet transfusion may be needed along with red cell transfusion. Liver functions should be monitored.

ADVANCED RESEARCHES

Control of mosquito (vector) transmission, development of dengue vaccine, and antiviral drugs constitute future directions with an aim to prevent and treat dengue infection.

Control of mosquito (vector) transmission can be done by keeping guppies ( Poecilia reticulata ) or copepods ( doridicola agilis ) in standing water, and infecting the mosquito population with bacteria of the Wolbachia genus.[ 43 ]

Due to the progressing transmission and enhancing severity of dengue infection, the necessity to develop a dengue vaccine has gained considerable importance. There is a worldwide public health need for a safe, effective, and economic tetravalent dengue vaccine. Complex pathology, the prerequisite to control four virus serotypes, and inadequate investment by vaccine designers have hindered vaccine advancement.[ 45 ]

Scrupulous attempts are aimed to develop antiviral drugs that can be used to manage DF and avoid the life-threatening episodes.[ 46 , 47 ]

Dengue has evolved as a global life-threatening public health concern, affecting around 2.5 billion individuals in more than 100 countries. The physician should be aware about the varied clinical manifestations of this condition and ensure an early and adequate treatment plan. Future directions to combat this dreadful disease aim at methods of mosquito control, development of vaccine, and antiviral drug regimen.

Paragraph on Dengue Fever (200 Words)

You may read: Report on Dengue Fever for HSC

Dengue is a viral disease spread by a mosquito named “Aedes”. The “Aedes” mosquito is the culprit. The disease prevails mostly in tropical countries like ours.

The main culprit “Aedes” mosquito is born in stagnant fresh water and rainwater. There remains clogged water in flowerpots, damaged tyres, drains, waste plastic bags, and bottles around our home. Sometimes, we see water clogged on the roof of buildings. Dengue causes a sustained high-grade fever, red rashes all over the body, much pain around, inside or behind the eyes, nausea and vomiting, abdominal pain, diarrhoea, and muscle aches. There are two types of dengue.

These are classic dengue and dengue hemorrhagic. Normally, classic dengue recovery occurs more quickly but dengue hemorrhagic decreases the platelet count of the blood, It causes bleeding, organ failure or even death.

There is no vaccine against dengue. So prevention is very crucial. We must keep our household areas clean so that water can not be clogged in flowerpots, vases, tyres etc. Besides, we must protect ourselves from mosquito bites. That’s why we should always wear protective clothing like pants, long sleeves, and socks and use mosquito nets while sleeping. Above all, we had better consult a doctor if any fever persists for days.

Dengue Fever Paragraph 150 words (Class 8)

Dengue fever is a viral illness that is transmitted by mosquitoes. The symptoms of dengue fever include high fever, severe headache, joint and muscle pain, and rash. In Bangladesh, dengue fever has become a major public health concern, with frequent outbreaks occurring in recent years. The mosquito that transmits dengue fever breeds in stagnant water, which is abundant in Bangladesh due to the country’s geography and climate. Prevention measures such as eliminating mosquito breeding sites, using mosquito nets, and wearing protective clothing can help reduce the risk of contracting dengue fever. Early detection and treatment are also important for managing the illness and preventing complications. Health authorities in Bangladesh are working to increase awareness about dengue fever and improve prevention and treatment efforts to reduce the impact of this disease on the population.

Dengue Fever Paragraph 200 words (SSC)

Dengue fever is a prevalent mosquito-borne viral disease in Bangladesh, affecting thousands of people every year. The symptoms of dengue include high fever, headache, joint and muscle pain, and rashes. If not diagnosed and treated promptly, it can progress to severe dengue, which can be fatal. The Aedes mosquitoes that transmit dengue are most active during the day, so it is crucial to take preventive measures, such as using mosquito nets, wearing long-sleeved clothing, and applying insect repellent. In addition, it is vital to keep our surroundings clean and dispose of standing water, where mosquitoes breed. Dengue outbreaks in Bangladesh usually occur during the monsoon season, and the government takes measures to control the spread of the disease, such as fogging and spraying insecticides. However, the best defense against dengue is to raise awareness about the disease and take preventive measures to reduce the risk of mosquito bites.

Dengue Fever Paragraph 250 words (HSC)

Dengue fever is a mosquito-borne viral disease that has become a major public health concern in Bangladesh, with frequent outbreaks occurring in recent years. The virus is transmitted to humans through the bites of infected mosquitoes, primarily Aedes aegypti and Aedes albopictus. These mosquitoes breed in stagnant water, which is abundant in Bangladesh due to its geography and climate. The symptoms of dengue fever can range from mild to severe and can include high fever, severe headache, joint and muscle pain, and rash. In severe cases, dengue fever can lead to complications such as bleeding, shock, and organ failure.Prevention measures such as eliminating mosquito breeding sites, using mosquito nets, and wearing protective clothing can help reduce the risk of contracting dengue fever. Community participation in prevention efforts is crucial, as mosquitoes can breed in any standing water, including water in discarded containers, old tires, and flowerpots. Effective communication campaigns and education about dengue fever and its prevention are necessary to encourage communities to take action.Early detection and treatment are also important for managing the illness and preventing complications. If you suspect you have dengue fever, it is important to seek medical attention immediately. Dengue fever can be diagnosed through a blood test, and treatment typically involves rest, hydration, and pain relief medication. In severe cases, hospitalization may be required.Health authorities in Bangladesh are working to increase awareness about dengue fever and improve prevention and treatment efforts to reduce the impact of this disease on the population. The government has implemented a number of strategies, such as the distribution of mosquito nets, regular fumigation, and the establishment of dengue clinics in hospitals. These efforts have shown some success, with a decrease in the number of dengue cases reported in recent years.

Dengue fever is a significant public health issue in Bangladesh, affecting thousands of people every year. It is a mosquito-borne viral disease caused by the dengue virus and spread by the Aedes mosquito, which is most active during the day. The symptoms of dengue include high fever, headache, joint and muscle pain, and rashes, which can last up to a week. In severe cases, dengue can cause bleeding, shock, and organ failure, which can be life threatening.Prevention is crucial in controlling the spread of dengue. To reduce the risk of mosquito bites, it is essential to take preventive measures such as using mosquito nets, wearing long-sleeved clothing, and applying insect repellent. It is also crucial to keep our surroundings clean and dispose of standing water, where mosquitoes breed.Dengue outbreaks in Bangladesh usually occur during the monsoon season, when rainfall creates ideal breeding conditions for mosquitoes. The government takes various measures to control the spread of the disease, such as fogging and spraying insecticides. However, these measures alone are not enough to prevent dengue outbreaks.Therefore, raising awareness about dengue is crucial in preventing its spread. The government, along with healthcare professionals and NGOs, conducts awareness campaigns to educate people about the disease and its prevention. Schools and universities also play a vital role in raising awareness, as young people are at high risk of dengue.In recent years, the number of dengue cases in Bangladesh has increased significantly, and the disease has spread to new areas. The government has taken steps to address this issue, such as increasing the availability of diagnostic and treatment facilities and promoting research on the disease. However, to combat dengue effectively, a multi-sectoral approach is necessary, involving not only the government and healthcare professionals but also the community.In conclusion, dengue fever is a preventable disease that can be controlled by taking preventive measures and raising awareness about its prevention. By working together, we can reduce the incidence of dengue and create a safer and healthier Bangladesh.
