Dengue Fever
A mosquito-borne viral infection causing high fever, severe headache, and body pain.
This condition typically requires medical attention
If you suspect you have dengue fever, please consult a healthcare provider for proper evaluation and treatment.
Overview
Dengue fever is a viral infection spread by Aedes mosquitoes, primarily in tropical and subtropical regions. It causes sudden high fever, severe headache, pain behind the eyes, and joint/muscle pain (hence its nickname "breakbone fever"). While most people recover fully, some develop severe dengue (dengue hemorrhagic fever), which can be life-threatening. Dengue is common in parts of Asia, Latin America, Africa, and increasingly appearing in new areas due to climate change.
Common Age
Can affect any age; severe dengue more common in children
Prevalence
About 400 million infections yearly worldwide; endemic in 100+ countries
Duration
Acute illness 2-7 days; recovery may take weeks
Common Symptoms
- Sudden high fever (104°F/40°C)
- Severe headache (especially behind eyes)
- Severe joint and muscle pain
- Fatigue
- Nausea and vomiting
- Skin rash (appears 2-5 days after fever)
- Mild bleeding (nose, gums, easy bruising)
- Loss of appetite
- Swollen lymph nodes
Possible Causes
- Dengue virus (4 serotypes: DENV-1, 2, 3, 4)
- Transmitted by Aedes mosquitoes
- Mosquitoes bite during daytime, especially morning and evening
- Cannot spread person-to-person directly
- Previous infection with one type increases risk of severe dengue if infected with different type
Note: These are potential causes. A healthcare provider can help determine the specific cause in your case.

Detailed Treatment & Solutions
1HYDRATION
Critical to prevent complications. Drink water, oral rehydration solutions, coconut water, juice. Aim for 5+ glasses daily. Watch for signs of dehydration. IV fluids may be needed in severe cases.
2FEVER AND PAIN MANAGEMENT
Use acetaminophen (paracetamol) only. NEVER take aspirin, ibuprofen, or naproxen as they increase bleeding risk. Sponge with lukewarm water if fever is very high.
3REST
Complete bed rest recommended during acute phase. Avoid physical exertion. Most people feel better after 1 week but fatigue may last weeks. Gradual return to activity.
4MONITORING
Watch carefully during days 3-7 when fever decreases (this is when severe dengue can develop). Warning signs: severe abdominal pain, persistent vomiting, bleeding, lethargy, restlessness.
5MOSQUITO PREVENTION
Use repellent with DEET, picaridin, or IR3535. Wear long sleeves and pants. Stay in air-conditioned or screened areas. Remove standing water (breeding sites). Dengue mosquitoes bite during day.
6MEDICAL CARE
No specific antiviral treatment exists. Supportive care is key. Severe dengue requires hospital care. Dengue vaccine (Qdenga) now available in some regions for prevention.

Frequently Asked Questions
QCan I get dengue more than once?
Yes, you can get dengue up to 4 times because there are 4 different virus serotypes. Infection with one type gives lifetime immunity to that type only. Unfortunately, second infections (with different types) often cause more severe disease.
QWhen is dengue most dangerous?
Paradoxically, dengue is most dangerous when the fever starts going down (usually days 3-7). This is when severe dengue can develop. Watch carefully for warning signs during this critical period and seek immediate medical care if they appear.
