What is Dengue Fever?


Dengue fever is a mosquito-borne disease that affects millions of people worldwide each year.

 Dengue spreads rapidly and has a severe impact on affected communities and poses a major public health threat in tropical and subtropical regions of the world. Understanding the nature of this disease is important for developing effective prevention and control strategies.

Dengue virus belongs to the family Flaviviridae and has four serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), all of which can infect humans. The disease is spread by Aedes mosquitoes, especially Aedes aegypti and Aedes albopictus found in urban and urban areas. These mosquitoes are quite active during the day, so it is not easy to avoid mosquito bites in daily work.

Dengue fever has a wide range of symptoms, ranging from mild flu to severe and potentially fatal. The febrile phase is characterized by fever, severe headache, joint and muscle pain, and rash. Although most patients recover without any complications, some people develop more serious conditions such as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). DHF and DSS include bleeding, decreased platelet count, organ failure, and shock and require immediate medical attention.

What is Dengue Virus?

Dengue fever is a disease caused by the dengue virus, which is transmitted to humans through mosquito bites. The disease can be caused by one of four dengue serotypes (DEN-1, DEN-2, DEN-3 and DEN-4). Dengue fever is not contagious, meaning it does not spread directly from one person to another.

How is Dengue Fever Transmitted?

Dengue fever is transmitted by two types of mosquitoes: Aedes aegypti and Aedes albopictus. Common in cities and urban areas, these mosquitoes breed in stagnant water and bite during the day. When a mosquito bites a person infected with dengue, it becomes a contagious disease. Later, when it bites another person, it becomes infected and causes dengue fever.

What are Dengue Fever Symptoms?

Dengue fever can present with a variety of symptoms ranging from mild to severe. Common symptoms include fever, severe headache, joint and muscle pain, and skin rash. Some people may also experience nausea, vomiting, and minor bleeding such as nosebleeds or bleeding gums. In severe cases, dengue can progress to dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS), both of which can be life-threatening.

Social Impact of Dengue Fever

Dengue fever has a strong social impact, particularly in areas with high mosquito populations and limited medical care. Children are particularly vulnerable to dengue fever, a disease that can lead to extended hospital stays and financial impact on families. In addition, dengue fever can stress the health system and affect productivity due to sickness absence from work and school.

Diagnosis and Treatment of Dengue Fever

Diagnosing dengue fever can be difficult because early symptoms can resemble other illnesses (such as the flu). A prompt and accurate diagnosis is important to provide appropriate treatment and to prevent the problem. Doctors will use blood tests such as PCR and serology tests to detect the presence of dengue virus or antibodies.

Treatment focuses on managing symptoms and providing supportive care such as staying hydrated and pain relief. Severe cases require hospitalization and close follow-up, as well as interventions such as blood transfusions in patients with severe bleeding or low platelet counts.

Prevention of Dengue

Because there is no specific treatment for dengue, prevention is important to contain the spread of dengue. Public health measures include vector control to reduce mosquito populations. This includes removing mosquitoes, such as standing water in containers or tires. Using pesticides and netting can help protect people from mosquitoes.
Community awareness and education is important to promote preventive measures and encourage community participation in mosquito control. An integrated management (IVM) approach that includes the coordination of various factors such as health, environment and urban planning can be effective for reducing the mosquito population and limiting the spread of the disease.

Ongoing Research and Future Perspectives about Dengue

Scientists and researchers around the world are constantly working to develop vaccines for dengue fever to prevent the disease. Many candidate vaccines are currently in clinical trials, and some have been approved for use in certain areas.
Dengue vaccine is designed to provide immunity against all four serotypes, reducing the risk of serious illness and potential transmission.

In addition to developing a vaccine, the goal of ongoing research is to improve dengue diagnosis and treatment options. Understanding the interactions between viruses, mosquitoes and humans is critical to developing effective strategies to contain dengue transmission and its impact on communities.


Dengue is still a mosquito-borne disease that affects millions of people worldwide. Understanding its transmission, symptoms and impact on society is important to implement effective prevention and control measures.

As research continues to develop vaccines and improve diagnosis and treatment options, we can work towards a future where dengue fever is no longer a major public health threat and where communities can thrive without fear of its effects.
