目的了解1963～2012年寿光市细菌性痢疾的流行特征,为制定相关防控措施提供依据。方法采用描述流行病学方法对1963～2012年寿光市的菌痢疫情资料进行回顾性分析。结果 1963～2012年寿光市共报告细菌性痢疾81 404例,死亡27例,各年发病率为23.60/10万～1 539.76/10万,年均发病率为171.96/10万,年均死亡率0.28/10万。男女发病性别比为1.63∶1。7～8月为发病高峰。1986～2012年,<1岁组年均发病率最高为980.96/10万,其次为1～5岁组为319.04/10万。发病的职业构成以散居儿童最多占42.23%,其次为农民占33.86%。自70年代至今,与辖区乡镇相比市区居民的发病率更高,二者差异有统计学意义(P<0.01)。结论 50年来寿光市细菌性痢疾的发病总体呈下降趋势,但目前发病率仍维持在较高水平。
Objective To understand the epidemic characteristics of bacillary dysentery in Shouguang City from 1963 to 2012 and provide evidence for the establishment of relevant prevention and control measures. Methods Descriptive epidemiological methods were used to analyze the epidemic situation of bacillary dysenteriae in Shouguang City from 1963 to 2012. Results A total of 81 404 bacterial dysentery cases were reported in Shouguang City from 1963 to 2012, with 27 deaths. The annual incidence rate was 23.60 / 100000 ~ 1539.76 / 100000 with an average annual incidence rate of 171.96 / 100000. The average annual mortality rate 0.28 / 100,000. Male and female incidence of sex ratio was 1. 63: 1. 7 to August for the peak incidence. From 1986 to 2012, the average annual incidence of <1 year old group was 980.96 / 100000, followed by 319.04 / 100000 group of 1 ~ 5 years old group. Occupational diseases accounted for up to 42.23% of scattered children, followed by farmers accounted for 33.86%. Since the 1970s, the incidence of urban residents was higher than that of towns and villages in the area, with significant difference (P <0.01). Conclusions The incidence of bacillary dysentery in Shouguang City has shown a decreasing trend over the past 50 years, but the incidence is still at a relatively high level.
