METHODS: Intermsof the indices of conventional malariometric survey used in thenationwide anti malaria campaign. RESULTS:(1)The annual parasite incidence(API) varied from 0.0056‰ to 0.00033‰;(2)the average positive rate of febrile cases during case detection among inhabitants was 0.73,and the average parasite rate of mass blood examination was 0.82;(3)the average positive rate of febrile cases and the average parasite rate in mobile population was 413.1and 7.06,respectively;(4)there were 10.7% active foci among a total of 994 residual malaria foci. CONCLUSION:The increasing imported malaria is a risk factor in this basically eliminated malaria area and should be promptly managed andkeptundersurveillance.
