It breeds in clear water, collected in any containers, like broken pots, tender coconut shells. People should avoid stagnant water around the house.
They should keep the environment clean and not dispose of the solid waste material including shoes, where water can collect. People should clean and refill the water storage containers, once a week, and cover them. Morbidity and Mortality can be reduced, if treated in the initial stage. So people should consult a doctor if they experience sudden high fever, severe headache, pain behind the eyes, extreme pain in muscles and joints, nausea, or vomiting, they said.
