India contributes approximately 70% to the malaria burden of Southeast Asia. The transmission of disease in the country is generally hypoendemic, seasonal and unstable. Most researchers focus upon the hyperendemic malarious regions with stable malaria transmission. There is paucity of data regarding malaria transmission in hypoendemic regions, here we are presenting an epidemiological picture of clinical manifestations through a hospital-based survey in Aligarh, India, during 2016-18. Two thousand sixty-eight patients were diagnosed with malaria infection in Jawaharlal Nehru Medical College and Hospital (JNMCH), out of which 1104 were enrolled for clinical analysis. Ninety per cent of the cases were reported during July-November, and the rest in the dry season. A progressive increase in the prevalence rate was observed during the study period, i.e. 4.8, 7.57 and 8.7% in 2016, 2017 and 2018, respectively. Of the total cases, 75.77% had malaria, while rest suffered from malaria. The risk of disease was significantly higher in the age group 0-15 years compared to all other age groups ( < .0001). The infection rate was higher in males (61%) compared to females (39%)  < .0001. Overall 8.6% of the patients had severe malaria who fulfilled the WHO criteria. The increasing rate of malaria infection during the study period and a considerable no. of severe vivax malaria cases warrant an efficient disease monitoring system, pointing towards the need to carry out micro-epidemiological studies in order to estimate the real burden of malaria in the country.
