Dengue Mosquito Bites: Symptoms, Identification, and When to Seek Care

Identifying Dengue Mosquito Bites

Aedes aegypti and Aedes albopictus mosquitoes transmit dengue. Their bites appear as:

• Small, red, raised bumps (papules)
• Often in clusters or lines
• Intensely itchy
• Usually on exposed skin (ankles, arms, neck)

Bites typically resolve in a few days.

Warning Signs of Dengue Infection

The bite itself doesn't cause dengue; the virus does. Seek medical attention if, within 4–10 days of a bite, you develop:

• High fever (104°F / 40°C)
• Severe headache, pain behind eyes
• Muscle and joint pain ("breakbone fever")
• Nausea, vomiting
• Rash
• Bleeding gums, nosebleeds, easy bruising (signs of severe dengue)

What to Do

1. Monitor for symptoms after a bite in a dengue-endemic area.
2. Stay hydrated; use acetaminophen for fever/pain (avoid NSAIDs like ibuprofen—risk of bleeding).
3. See a doctor for testing (NS1 antigen, PCR, IgM).
4. Eliminate standing water to reduce mosquito breeding.
