[A general discription and analysis of plague epidemiology in China during 1990-1994]

The result of systematic and active surveillance indicates that the human cases increased dramatically in the 90's. The main reason was due to the renewed activity of R. flavipectus nidi in Yunnan Province, but has basically been under control. As the effort of prevention, enzootic plague in southeast costal and northeast regions has been stabilized for thirty to forty years. The policy of plague control in China is to put prevention first. The measures include surveillance, deratization and depulization, health education and emergency management in epidemic areas.
