Spatial Distribution and Epidemiological Characteristics of Foodborne Disease in Zhejiang Province, China

Foodborne Disease (FBD) is the most common disease around the world. Based on the surveillance data of FBD in Zhejiang Province from Jan 1, 2013 to Dec 31, 2015, including 26721 illness cases, 1591 hospitalizations and 6 deaths. We conducted exploratory data analysis to evaluate eidemiological characteristics. The spatial autocorrelation analysis was performed to detect the clusters at county level. The results show that the high peaks usually occurred in summer and autumn, and high-high pattern areas were mainly concentrated in the southwest counties. Most likely clusters were mainly located in the northern counties over the period from May to October, which deserved public's attention. Incidence rates of illness and hospitalization for males were higher than females. People in 18-35 group were suspected to FBD and the elderly over 60 had a highest hospitalized percentage. Peasants and children accounted for about 40% of illness cases, and over 50% of hospitalized cases were peasants (especially in spring and winter). Norovirus was the major cause in spring and winter, while Vibrio parahaemolyticus and Salmonella were the top two pathogens in summer and autumn.
