Abstract:
Objective To analyze the outcome of surveillance results on plague and to provide the evidences for the policy making in Longlin county Guangxi. Methods The epidemic data and the surveillance results of plague were analyzed and assessed with epidemiology methods in Longlin county Guangxi from 2000 to 2009, and the density of rodents, the rodents infected with flea, flea index and other indicators were calculated. Regional composition of the rats and fleas were analyzed. Results A totally of 4829 rats were captured and 4737 fleas were collected in the past 10 years, Rattus Flavipestus(81.92%,3956/4829) and Xenopsylla Cheopis (79.04%,3744/4737) were dominant species. The annual average density of rodents, the rodents infected with flea, index of flea were 3.30%(4829/146 206), 27.99%(1351/4827) and 0.98(4737/4827), respectively. A totally of 4792 rats were examined and 10 strains Yersinia Pestis were isolated. Indirect hemorrhagic assessed(IHA) was used to test the F1 antibody against plague in the blood serum of the rats and indicator animals, and 3 positive rats and 24 positive animals were found, respectively. Twenty seven natural villages in 3 towns had been involved in the plague. Conclusions The plague foci exists in Longlin county of Guangxi province. The plague foci in the areas have the same feature with the plague foci of Rattus Flavipectus. There is a potential risk for plague in this region, we should improve the quality of surveillance, increase indicator animals of the plague, and try to apply new surveillance method.
