Abstract

A study was carried out to find out co-relation between rainfall and
instances of malaria infection in different villages of Purnia district . The study
clearly indicates that there occurs a high positive co-relation between rainfall and
instances of malaria in the studied villages of the district. There occurs a gradual
increase in instances of malaria with gradual rise in rainfalls. The study also indicates
that besides rainfall, ambient temperature also plays a key role in the incidence of
malaria as in certain months the incidence of malaria was not found having but
rainfall. Maximum incidence of malaria was noticed during rainy season followed by
