Title: Analysis on epidemic characteristics of bacillary dysentery in Jiangsu province from 2004 to 2010
Abstract: Objective To explore the epidemic characteristics of bacillary dysentery in Jiangsu province from 2004 to 2010 and to provide scientific basis for formulating prevention and control strategies.Methods Retrospective analysis was carried on surveillance data of bacillary dysentery in Jiangsu province from 2004 to 2010,Linear regression was performed to analyze the incidence and constituent ratio through the SPSS 11.5 statistical software.Results The annual average incidence of bacillary dysentery was 17.40 per 100 000,which showed a degressive trend year after year.The epidemic of this disease reached peak between June and September each year.The incidence of bacillary dysentery in developed areas of southern Jiangsu was higher than that in other developing areas of northern Jiangsu.Children under 5 years old had the highest incidence.The proportion of male to female was 1∶0.79.With regard to occupational distribution,scattered children,peasants,students and workers were the major infected population.The detection rate of Shigella Flexneri gradually decreased,while Shigella Sonnei increased gradually.Meantime,the predominant serotypes of Shigella Flexneri were also continually changing each year.Conclusion The incidence rate of bacillary dysentery kept in a relatively low level in Jiangsu province,but prevention and control of bacillary dysentery is still facing a challenge because of widespread epidemic factors and continuous diversification of bacterial epidemic types.
