As mosquitoes cause this disease, it is important to keep mosquitoes at bay. Try to keep your home and surroundings free of mosquito breeding grounds, such as stagnant water.

Remove empty containers or old flowerpots where water can collect, especially in the monsoon season. Add a few drops of kerosene oil to coolers, open drains, small ponds and other places where water tends to collect and sleep under a treated mosquito net.
