Epidemiology of bacillary dysentery in Ningbo, Zhejiang,2004-2011

  • 摘要: 目的 了解宁波市近年来细菌性痢疾的流行特征,为指导科学防控提供依据。 方法 对宁波市2004-2011年细菌性痢疾疫情和病原学监测资料进行描述流行病学分析。 结果 2004-2011年宁波市细菌性痢疾年发病率在8.35/10万~42.59/10万,平均为24.25/10万。2007年至今疫情一直表现为散发状态。全年均可发病,但以夏秋季尤其是8-9月为高峰。发病率以0~4岁儿童最高,其次为85岁及以上年龄组。 20岁以下和75岁及以上年龄段男性发病率高于女性。与周边县(区)相比,市区居民的发病率更高。不同职业发病数顺位由高到低依次为散居儿童、农民、工人和学生。菌株分型以福氏和宋内志贺菌为主,分别占59.76%和39.02%。 结论 宁波市细菌性痢疾发病逐年下降,已维持在低发水平。

Methods Descriptive epidemiological analysis was conducted on the incidence data and etiological surveillance Results of bacillary dysentery in Ningbo from 2004 to 2011. Results The incidence of bacillary dysentery ranged from 8.35/lakh to 42.59/lakh during this period, the annual average incidence was 24.25/lakh. No outbreak of bacillary dysentery had been reported since 2007. The cases occurred all the year round and peaked during August-September. All age groups were affected by bacillary dysentery, but the incidence in age group 0-4 years was highest, followed by that in age group 85 year. The incidence was higher in males than in females in age groups 0-19 years and 75 years. Compared with neighboring counties, the incidence in urban area was higher. The cases were mainly distributed in children outside child care settings, farmers, workers and students. The etiological surveillance indicated that the major pathogens were Shigella flexneri and Shigella sonnei with the positive rates of 59.76% and 39.02%, respectively.
