Plague

Plague (plague) is a severe infectious disease transmitted mainly by rat fleas, which is a natural epidemic of wild rodents. Clinical manifestations include fever, severe toxemia symptoms, lymphadenopathy, pneumonia, and bleeding tendency. There have been many plagues in the history of the world, with tens of millions of dead and extremely high mortality. Human plagues were reported worldwide in 1992 in Brazil, China, Madagascar, Mongolia, Myanmar, Peru, the United States, Vietnam, and Zaire, with a total of 1582 cases. The majority of patients were in Africa, with a case fatality rate of 8.7%. 29 cases in China, concentrated in Xishuangbanna. China also had many epidemics before liberation. The confirmed plague origins in China are distributed in 17 provinces (autonomous regions) and 216 counties, and animal plagues continue. The human plague expanded from two provinces (Qinghai, Tibet) in 1985 to six provinces including Yunnan, Inner Mongolia, Xinjiang, and Gansu. The prevention and control of plague in China is still very important.
