Malaria causes large socio-economic load on humanity. Malaria is one of the important community health problems and it is prevalent in 104 tropical and subtropical countries of the world. India alone contributes 76% of the total cases. Malaria is caused by Plasmodium parasite and spreads through the bite of female Anopheles mosquito, well-known vector for malaria. Objectives of the study were to know the prevalence of different malarial species and to know the seasonal trend of malaria. This study was done in Bharatpur district Rajasthan from Jan 2011 to December 2017. Total 2057847 samples were collected. Microscopic examination was used for the diagnosis of malaria by preparing thick and thin smears stained with JSB I & II. 2057847 samples wer collected out of which 12201 were found microscopically positive (0.59%). Among the cases found positive, only Plasmodium vivax and Plasmodium falciparum species were found. Prevalence of P. vivax (99.19%) was more as compared to P. falciparum (0.81%) and peak positivity rate was found from July to October period. In present study P. vivax was the most common species. This indicates that P. vivax is the most widespread malarial infection in India which results in a pronounced morbidity and the seasonal prevalence was observed high in July to October. In order to implement effective preventive measures, proper surveillance on the incidence and prevalence of malaria is required.
