Malaria risk in Thiruvananthapuram

Malaria in Thiruvananthapuram: Practical Prevention Guide Malaria is a mosquito-borne disease caused by Plasmodium parasites, transmitted through the bite of infected female Anopheles mosquitoes. Symptoms include high fever, chills, headache, and body aches. If untreated, it can become severe and life-threatening. Thiruvananthapuram's risk score of 67/100 reflects its tropical climate, monsoon flooding, and dense urban waterlogging that create ideal mosquito breeding conditions. Local risk factors include stagnant water in construction sites, uncovered household water storage containers, coconut husk piles, and poorly drained drains. Peak transmission occurs during and after the monsoon seasons from June to November. Areas near marshlands, paddy fields, and poorly maintained drainage systems carry higher risk. Five essential prevention steps: 1. Eliminate breeding sites around your home. Empty and scrub water storage containers weekly. Drain standing water from flower pots, discarded tires, coconut shells, and rooftop gutters. Keep surroundings clean and dry. 2. Use insecticide-treated bed nets every night, especially from dusk to dawn when Anopheles mosquitoes bite most actively. Ensure nets are properly tucked under mattresses without holes or tears. 3. Apply DEET-based or citronella repellents on exposed skin during evening hours. Wear long-sleeved clothing and full-length pants when outdoors after sunset. 4. Install window and door screens where possible. Use indoor residual spraying with approved insecticides. Close windows before dusk to prevent mosquito entry. 5. Seek immediate medical attention if you develop fever with chills within days to weeks of exposure. Early diagnosis through blood smear testing and prompt treatment with antimalarial medication prevents severe complications. Do not self-medicate. Residents in higher-risk wards near Veli, Akkulam, Vellayani, and Kazhakuttom should remain particularly vigilant during monsoon months.
