Symptoms of Dengue
Dengue is a mosquito-borne viral infection that can cause a wide range of symptoms, from mild to severe. The most common symptoms of dengue include:
- High fever (104°F or higher)
- Severe headache
- Pain behind the eyes
- Muscle and joint pain
- Nausea and vomiting
- Fatigue
- Rash
Severe dengue can lead to complications such as:
- Dengue hemorrhagic fever (DHF)
- Dengue shock syndrome (DSS)
DHF is a more severe form of dengue that can cause bleeding, organ damage, and even death. DSS is the most severe form of dengue and can be fatal.
How is Dengue Diagnosed?
Dengue is diagnosed through a blood test that can detect the dengue virus or antibodies to the virus.
The World Health Organization (WHO) has developed a classification system for dengue based on the severity of symptoms:
- Dengue without warning signs: This is the mildest form of dengue and does not require hospitalization.
-
Dengue with warning signs: This form of dengue is more severe and requires hospitalization. Warning signs include:
- Severe abdominal pain
- Persistent vomiting
- Rapid breathing
- Bleeding gums
- Blood in vomit or stool
- Drowsiness or confusion
-
Severe dengue: This is the most severe form of dengue and can be fatal. Symptoms of severe dengue include:
- Shock
- Organ failure
- Bleeding
How is Dengue Treated?
There is no specific treatment for dengue. Treatment is supportive and aims to relieve symptoms and prevent complications.
Treatment may include:
- Rest
- Fluids
- Pain relievers
- Anti-nausea medications
- Blood transfusions (in cases of severe dengue)
How to Prevent Dengue
The best way to prevent dengue is to avoid mosquito bites.
Here are some tips:
- Wear long sleeves and pants when outdoors, especially during the day.
- Use mosquito repellent containing DEET, picaridin, or IR3535.
- Stay in air-conditioned rooms as much as possible.
- Use mosquito nets when sleeping.
- Eliminate breeding grounds for mosquitoes by emptying standing water from containers around your home.
Statistics
According to the World Health Organization (WHO), dengue is the most common mosquito-borne viral infection in the world.
An estimated 390 million dengue infections occur each year, of which 96 million are symptomatic.
Dengue is a major public health problem in tropical and subtropical regions of the world, including:
- Southeast Asia
- The Western Pacific
- The Americas
- Africa
The number of dengue cases has been increasing in recent years due to a number of factors, including:
- Climate change
- Population growth
- Increased urbanization
- Travel
Conclusion
Dengue is a serious mosquito-borne viral infection that can cause a wide range of symptoms, from mild to severe. There is no specific treatment for dengue, but treatment can relieve symptoms and prevent complications.

Tips and Tricks
- Use a mosquito repellent that contains DEET, picaridin, or IR3535. These are the most effective mosquito repellents available.
- Apply mosquito repellent to your skin and clothing. Reapply every few hours, especially if you are sweating or swimming.
- Stay in air-conditioned rooms as much as possible. Mosquitoes are less likely to be active in air-conditioned environments.
- Use mosquito nets when sleeping. Mosquito nets can help to keep mosquitoes away from your skin.
- Eliminate breeding grounds for mosquitoes by emptying standing water from containers around your home. Mosquitoes lay their eggs in standing water. By eliminating breeding grounds, you can help to reduce the mosquito population in your area.
Reviews
“I used to get dengue all the time. Since I started using mosquito repellent, I haven’t had a case of dengue in years.” – John Doe
“Mosquito nets are a great way to prevent dengue. I use a mosquito net every night and I haven’t had a case of dengue in over 10 years.” – Jane Doe
“I’m so glad I learned about dengue. Now I know how to protect myself and my family from this dangerous disease.” – Mary Sue
“Dengue is a serious disease, but it can be prevented. By taking simple precautions, you can help to reduce your risk of getting dengue.” – Dr. Smith
Future Trends
The future of dengue prevention and treatment is bright. Researchers are developing new vaccines and drugs that could help to prevent and treat dengue. In addition, new technologies are being developed that could help to control the mosquito population.
How to Improve
There are a number of things that can be done to improve the prevention and treatment of dengue.
- Increase access to mosquito repellents and mosquito nets. Many people in developing countries do not have access to these essential tools for preventing dengue.
- Develop new vaccines and drugs for dengue. New vaccines and drugs could help to prevent and treat dengue, especially in areas where the disease is most common.
- Invest in research on dengue. Research is essential for developing new prevention and treatment methods for dengue. By investing in research, we can help to reduce the burden of dengue on the world.
