Objective To understand the epidemic characteristics and trends of bacillary dysentery in Jiangyin City and provide a scientific basis for making prevention and control measures. Methods Descriptive epidemiological analysis was used to analyze the epidemic situation of bacillary dysentery in Jiangyin City from 2005 to 2011. Results A total of 1 841 cases of bacillary dysentery were reported in Jiangyin from 2005 to 2011, with an average annual incidence of 14.76 / 100 000, which showed a declining trend year by year. The incidence of bacterial diarrhea in all age groups was higher than that in 20-59 years old Accounting for 45.52% of the total number of cases; occupational distribution is mainly farmers, scattered children, workers and students, accounting for 73.06% of the total number of cases; the incidence has obvious seasonal, the most incidence in June to October, Accounting for 70.83% of the total annual incidence. Conclusions The epidemic situation of bacillary dysentery in Jiangyin City decreased year by year, but due to the prevalence of epidemic factors, it still maintained a certain level of incidence and the situation of prevention and control was still severe.
