Surveillance of antimalarial drug resistance in China in the 1980s-1990s.

ABSTRACT: Since the successful preparation of the microplates and the medium for field application, the resistance degree and its geographical distribution of chloroquine-resistant Plasmodium falciparum, the fluctuation of the resistance degree of P. falciparum to chloroquine, and the sensitivity of the parasite to commonly used antimalarial drugs were investigated between 1980 and 2003 by the in vitro microtest and the in vivo four-week test recommended by the World Health Organization (WHO). The results indicated that chloroquine-resistant falciparum malaria was present in all eight provinces/autonomous regions endemic for falciparum malaria in China, and the resistance was high and widely distributed in the Hainan and Yunnan provinces.
