INTRODUCTION: Malaria is an infectious disease caused by the protozoa of the genus Plasmodium. It is the 5th deadliest infectious disease. India accounts for 58% of all the malaria infection among South East Asia & Jharkhand carries the burden of about 25 % of all malaria cases in India.. MATERIALS & METHODS : This is a retrospective study from Jan 2017 – july 2017 in which all 24 districts of Jharkhand accounting total of 1901978 cases . The diagnosis of malaria on basis of species were studied. The blood sample were collected at PHC, CHC & Sadar Hospital from above included cases, where the diagnosis were made by PERIPHERAL BLOOD SMEAR – THICK FILM & THIN FILM or SLIDE TEST METHOD. RESULTS : In our study from Jan – July 2017; we screened total 1901978 blood samples in which 51109 patients diagnosed with malaria. Among them, 24175 patients were of Plasmodium falciparum & 26934 of Plasmodium vivax. Of all the diagnosed cases, 25017 were males and 25092 were females. Maximum prevelance was found in WEST SINGHBHUM district (9780) and JAMTARA district was found to have least cases(10).Maximum cases of P.f found in WEST SINGHBHUM (7457) & GARHWA accounted for maximum P.v cases(3971). DISCUSSION and CONCLUSSION: Heavy burden of malaria infection in Jharkhand can be efficiently reduced by early diagnosis & treatment alongwith taking strict preventive measures like promoting use of mosquito nets, keeping surrounding clean and enforcing adequate chemoprophylaxis. Due to efficient implementation of several state malaria programmes ,mortality due to malaria has been drastically reduced, same reflected in our study as there was 0 mortality reported between Jan – July 2017.
