Malaria risk in Kolkata

Malaria Prevention Guide for Kolkata (Risk Score: 67/100) What is Malaria Malaria is a life-threatening disease caused by Plasmodium parasites transmitted through the bite of infected female Anopheles mosquitoes. Symptoms include high fever, chills, headache, body ache, and fatigue. In severe cases, it can lead to organ failure and death if untreated. Local Risk Factors in Kolkata Kolkata's tropical climate creates year-round mosquito breeding. Stagnant water in drains, construction sites, and uncovered water containers around homes serve as breeding grounds. Overcrowded residential areas with poor drainage increase exposure. Peak risk occurs during monsoon season (June–October) when waterlogging is common. Densely populated neighborhoods near wetlands and the Hooghly River face higher transmission intensity. Actionable Prevention Steps 1. Use insecticide-treated bed nets every night. Ensure no gaps or holes exist. Re-treat nets every six months or as directed. 2. Eliminate stagnant water around your home weekly. Empty flower pots, buckets, and discarded tires. Report blocked drains to Kolkata Municipal Corporation. 3. Apply DEET-based repellent on exposed skin from dusk to dawn when mosquitoes are active. 4. Wear long sleeves and pants during evening hours, especially near waterlogged areas. 5. Seek immediate medical testing if fever develops within two weeks of exposure. Early treatment prevents complications. 6. Keep windows screened or use indoor insecticide sprays approved by local health authorities. 7. Cooperate with municipal fogging drives and allow health workers access for community spraying. Travelers should consult a doctor about prophylactic medication before visiting high-risk zones within the city.
