【Abstract】 Objective To analyse epidemiological features and control effect for the outbreak of plague at Longlin in the year of 2000, a western minority nationality county at the Guangxi. Methods Using descriptive study or descriptive epidemiology, detecting Fraction I antibody of Yersinia pestis among dogs, cats, rats and patients of bubonic plague by indirect hemagglutination assay (IHA). Results Epidemic outbreak of plague occurs among the 13 villages in 2 towns and a factory with 42 cases of bubonic plague. Incidence rate of the disease is 1.06%. Prevalent period is from March to October and July is the most prevalent time. Most patients are children and young people, aging from 7 months to 29 years old. FI antibody have be detected by IHA in 1 of 119 rats, 8 of 71 domestic dogs and 6 of 13 domestic cats separately. 11 of 53 deceased rats were detected bacteria Yersinia pestis by culture. Conclusions Epidemic focus distribute around the region of Tianshengqiao reservoir. Epidemiological features are as same as Yunnan’s. The changed entironment may be the main cause of the epidemic outbreak following the high density of rat and flea around the reservoir.更多还原
