Major achievements and experience in filariasis control in the People's Republic of China. National Technical Steering Group for Filariasis Control and Research.

Filariasis control including a preparatory phase in the early 50s and two more extensive campaigns in the late 50s and 70s, has gained remarkable achievements. By the end of 1987, filariasis in 781 (90.4%) of 864 counties/cities was brought under control, i.e., the microfilariasis rate declined to less than 1% in the whole population in every village concerned. At present, there remain about 2,446,000 filariasis cases, accounting for 7.9% of 30,099,400 before nationwide campaigns. Microfilaria carriers among the remaining cases amounted to 1,473,000 and amicrofilaremic but symptomatic, to 973,000. The major experience comprises the integration of the control project into national health program, the mobilization of various sectors, including the community, the investigators and technical personnel in research institutions and control services all to participate and cooperate in problems and difficulties encountered.
