First thing to try: Hot fomentations over painful areas bring relief

🌿 Overview
Dengue fever primarily occurs in tropical and subtropical regions. It is transmitted by the Aedes aegypti mosquito, which bites during daylight hours. Onset is abrupt with rapid rise in temperature. The pain in the joints is so severe that the disease is called 'breakbone fever.' There is no specific drug treatment — recovery takes weeks. One attack provides approximately one year of immunity.
Common signs
- Onset 4–10 days after mosquito bite — abrupt, with rapidly rising temperature (sometimes to 106°F)
- Flushed, congested face and marked soreness in the eyeballs
- Severe pain in the head, lower back, and joints ('breakbone')
- Slow pulse and low blood pressure
- After 1–3 days, temperature rises again with second wave of pain and mental depression
- Eruption appearing like measles appears during second wave
- Convalescence is slow; death rarely occurs

- No vaccine or specific drug exists — only supportive care
- Travelers to tropical regions should be aware that dengue is common and daylight exposure to mosquitoes is the risk
🩺 When to see a doctor
- For diagnosis and monitoring, especially if traveling.
- Emergency care for any bleeding signs or rapid deterioration (dengue hemorrhagic fever).
