Epidemiological observations on malaria in some parts of Tengakhat PHC, Dibrugarh district, Assam.
A three year study carried out in 44 villages (pop. 17,938) reveals seasonal transmission of malaria i.e., from June to November. The incidence of malaria was high in the year 1988 in comparison to that of 1987 and 1989. P. falciparum was the predominant species. The population living in forest fringe areas were more prone to malaria than the rest. Anopheles nigerrimus, An. kochi, An. karwari and An. philippinensis were most abundant among the 16 anopheline species collected. Known vectors of malaria such as An. minimus, An. philippinensis, An. annularis and An. dirus were detected. An. dirus was incriminated as vector during this study.
