Abstract:
Objective To analyze surveillance and survey data in Zhejiang Province,and to learn the distribution of the leptospirosis of the host animals and the crowd,in order to provide the basis for prevention and control.Methods Descriptive epidemiology and statistical analysis were conducted.The kidneys of mouse,frog,pig,and duck were collected for pathogen isolation.The serum samples of the clinic diagnosed patients and the host animals were tested by microscopic agglutination test or antibody.Results There were 1 31 cases of leptospirosis in Zhejiang Province from 2005 to 201 4, including 3 cases died.The incidence rate,mortality rate and fatality rate were 0. 025 2/1 00 000,0. 000 6/1 00 000,and 2. 29%,respectively. The cases were reported in all the areas except Zhoushan and Huzhou. The main endemic distributions were mountain areas of southern and central Zhejiang Province.The positive rate in blood of duck was highest and the main flora was icteroheamorrhagiae.The floras in patients'serum antibody were icteroheamorrhagiae and leptospira hebdomadis.The flora in patients was incongruous with the host animals.Conclusion The incidence of leptospirosis remains at low level in recent years in Zhejiang Province.The bacterial flora distribution was stable,but the outbreak of leptospirosis due to strain changing should be prevented.
