[Malaria situation in the People's Republic of China in 1993. Advisory Committee on Malaria, MOPH].

According to case reporting from different provinces/autonomous regions/municipalities (P/A/M), the number of malaria cases amounted to 58,569 in the country (Taiwan not included) in 1993, the mean incidence being 4.982 per a hundred thousand, and the lethal cases due to malaria were 19. Among a total of 1.0862 billion population residing in areas where there were no reported malaria cases or the incidence was below 0.01%, 78.9 million in areas with an incidence of 0.10-1% and 10.6 million in areas with an incidence of 0.101-1% were detected. In Wanding City with a population of 10,000 on the border of Yunnan Province, high incidence of surpassing 1% was still revealed. The results of malaria surveillance in major endemic areas situated in 17 P/A/M with a coverage of 0.526 billion population indicated that 68,594 positive cases were detected from 12.423 million febrile patients undergone blood examination, showing a mean positive rate of 0.55%. 7,466 malaria parasite carriers were disclosed from target and migratory population in general examination, the mean parasite carrier rate being 1.26%. Because the province-based case reporting did not include migratory immigrants, and case missing was likely unavoidable during the reporting process at community level, the number of actual malaria cases was estimated to be no less than 100,000. 6,359 falciparum malaria cases (comprising mixed infections of Plasmodium falciparum and P. vivax) were detected in the whole country in 1993, accounting for 9.27% of the positive cases confirmed by blood examination; in addition three hundred and forty-four P. falciparum carriers were found.(ABSTRACT TRUNCATED AT 250 WORDS)
