Abstract: Malaria is a complex epidemic and one of the most serious vector-borne diseases world-wide. Malaria risk becomes higher in developing countries. A large number of malaria-causing factors including proximity to vector breeding site, inadequate use of control measures, and changes in land use play a big role. Recent trends indicate that there is a considerable increase in the frequency and severity of all epidemics namely Malaria, Chikungunya and Dengue outbreaks with a spread to both urban and rural areas of Karnataka State, India.
