Zika Virus risk in Kolkata

Zika Virus Prevention Guide for Kolkata Risk Score: 66/100 Zika virus is a mosquito-borne illness spread primarily through the bite of an infected Aedes aegypti mosquito, the same species that spreads dengue and chikungunya. Most infected adults experience mild symptoms including fever, rash, joint pain, and red eyes, but infection during pregnancy can cause serious birth defects including microcephaly. Kolkata faces elevated Zika risk due to its tropical monsoon climate and extensive waterlogging during monsoon season, which creates ideal breeding grounds for Aedes mosquitoes. The city's high population density, inadequate drainage systems, and warm temperatures year-round further amplify transmission risk. Prevention Steps Eliminate Standing Water Daily Empty and scrub all water containers, flower pots, discarded tires, and blocked drains around your home every single day. Aedes mosquitoes breed in even small amounts of clean standing water. Pay special attention during and after monsoon season from June through October when Kolkata experiences peak mosquito activity. Use EPA-Registered Repellents Apply mosquito repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin whenever you are outdoors, particularly during early morning and late evening when Aedes mosquitoes are most active. Reapply as directed on the product label. Install and Maintain Window Screens Fit all windows and doors with intact mesh screens. Sleep under insecticide-treated bed nets, especially if you live in low-lying areas of Kolkata prone to waterlogging such as parts of Salt Lake, Howrah, and central Kolkata neighborhoods. Wear Protective Clothing Cover exposed skin by wearing long-sleeved shirts, long pants, socks, and closed shoes when outdoors. Light-colored clothing is slightly less attractive to mosquitoes than dark colors. Seek Medical Attention Promptly If you develop fever, rash, joint pain, or red eyes, consult a healthcare provider immediately. Inform them about any recent travel to areas with known Zika transmission and request appropriate testing.
