ABSTRACT

Objective To learn the epidemiological characteristics and the disease burden of Vibrio parahaemolyticus diarrhea,and to provide the evidence for developing the scientific food -borne diseases prevention and control strategies. Methods Seven counties in Jiaxing City,and one general hospital from each was selected to be investigated.Feces or anal swabs of clinical diarrhea cases during the research period were collected to test Vibrio Parahaemolyticus,and the information about direct or indirect medical expense and other indirect expense were collected from the positive cases by household survey.Results 2 711 diarrhea cases were reported in 2014,and 71 cases were Vibrio parahaemolyticus positive,the infection rate was 2.62%.The number of cases peaked during July to October,and 33.80% were farmers. The majority of serum type were O3K6 and O4K8,taken up 70.42%.The disease burden of every case was 927.76 Yuan per time.The speculated annual total population economic burden of Vibrio parahaemolyticus diarrhea in Jiaxing was 15 963.8 thousand Yuan .The disease burder of rural cases was heavier than that of urban ones (P <0.05).The disease burden of females was heavier than males (P <0.05 ).The difference of disease burden among age groups were not statistically significant(P >0.05).Conclusion The disease burden of Vibrio parahaemolyticus diarrhea was heavy.The supervision of catering units and the advertisement of food hygiene information should be strengthened to lower the incidence level and disease burden.
