An epidemiological study of malaria in a north-Indian district.

A retrospective epidemiological study was carried out in Gurgaon District of Haryana, wherein data on malaria for a period of more than three decades (1958-1989) obtained from various sources were analysed. The study revealed a rise in the incidence of this disease from midsixties onwards and reached peak in 1976. Subsequently, there has been a gradual and sustained decline, possibly due to better implementation of Modified Plant of Operations (M.P.O.) in a more realistic and rational manner. Various malaria-metric indices like A.P.I., A.B.E.R., S.F.R., etc, have been analysed and attempts made to compare these parameters with that of Haryana State as well as with all India average for last few years. The analysis of the cases according to species, age of patients, seasonal incidence and temporal and spatial distribution have also been discussed.
