Malaria risk in Chennai

Malaria is a mosquito-borne disease caused by parasites transmitted through the bite of infected female Anopheles mosquitoes. Symptoms include high fever, chills, headache, and fatigue. If untreated, it can become severe and life-threatening. Chennai's tropical climate, coastal location, and urban waterlogging create breeding sites for mosquitoes, raising risk, especially during monsoon season. Stagnant water in construction sites, uncovered drains, and household containers provide mosquito habitats. Travelers and residents in areas with poor drainage face higher exposure. Risk score: 67/100. Actionable prevention steps: 1. Eliminate standing water around your home. Empty, scrub, and cover containers that collect water weekly, including flower pots, tires, and buckets. 2. Use insect repellent containing DEET (20–30%) on exposed skin, especially from dusk to dawn when mosquitoes are most active. 3. Sleep under insecticide-treated bed nets, particularly if staying in areas without air conditioning or window screens. 4. Wear long-sleeved clothing and pants during evening hours when outdoors. 5. Seek immediate medical attention if fever develops within weeks of exposure. Early treatment prevents severe complications. Prevention requires consistent effort. Combine environmental control with personal protection for best results.
