[Malaria situation in China, 1989. Advisory Committee on Parasitic Diseases, MOPH].
According to the case reporting system, malaria cases in the whole country (Taiwan Province not included) in 1989 accounted for 137,540, the incidence being 12.56/100,000, and lethal cases, 60. All these were close to those (134,156, 12.44/100,000, and 53) in 1988, while an insidious increase was in view. On the basis of county/city reckoning, about 984.5 million people reside in 2,576 counties/cities where malaria incidence was less than 0.1 per 1,000 (including non-endemic areas); 80.2 million people in 174 counties/cities with incidence of 0.1-1.0 per 1,000; 29.9 million people in 76 counties/cities with incidence of 1.1-10 per 1,000; and 500,000 people in 5 counties with an incidence above 10 per 1,000. Though malaria incidence in the whole nation continued to decline to some extent, informations from 3 provinces, i.e. southern Yunnan, Sichuan and middle Anhui showed an increase of 18.26%, 33.02% and 33.91% respectively, as compared with the incidence in 1988. This was due to incomplete implementation of malaria intervention strategies and the decrease in mosquito control areas. The general situation could be summarized as follows: in endemic areas with Anopheles sinensis as vector, the malaria incidence was steadily decreasing, malaria cases were few and scattered with the proportion of exogenous cases increasing; whereas in areas with A. anthropophagus, A. minimus and A. dirus as vectors, the prevalence was unstable and focal outbreaks often occurred. Such places were the main endemic areas of malaria. The endemic areas of falciparum malaria covered 69 counties of 5 provinces/autonomous region, while non-indigenous falciparum cases were reported from 73 counties of 8 provinces/municipality.(ABSTRACT TRUNCATED AT 250 WORDS)
