Abstract: Objective:To study the epidemic law of malarain in the area where Anopheles anthropophagus is the main vector of malara.Method:The incidence of malara was serveyed and analyzed in the endemic area in Hubei province from 1985 to 1999.Results:Since Anopheles anthropophagus was discovered in Hubei in 1985,It has been in 19 counties.Malaria incidence in An.anthropophagus complex vector areas were 2.1-25.9 times more(13.8 times on the average) than that in An.sinensis vector.The number of Malaria cases in those areas with 10.14%-25.82% population of the whole province accounted for 16.5%-85.95%(67.8% on the average) of the total cases of the whole province.Conclusion:The decline of malaria incidence in An anthropophagus compex vector areas were obviously lower than that in An.sinensis vector areas after application antimalarial measures.The malaria seasonal showed peaks in August,September and October,but An sinensis vector areas showe in July and August.
