[目的]分析探讨丽江市1983～2007年法定报告传染病流行特征及变化趋势,为各级政府制定防制策略提供科学依据。[方法]收集全市历年传染病疫情报告资料,采用时间序列和自身对照,用描述流行病学的方法进行统计分析。[结果]1983～2007年全市传染病历年波动在143.98～3701.33/10万之间。20世纪80年代发病率总体呈直线下降趋势;各年代发病均以肠道传染病为主,也呈下降趋势,构成比由73.07%下降到41.78%,2000年以来传染病谱发生了明显的变化,血源及性传播疾病发病率明显上升,构成比占传染病发病总数的26.97%,呼吸道传染病虽然下降明显,但构成比变化不大。80年代居前5位的传染病为痢疾、麻疹、百日咳、病毒性肝炎、伤寒,90年代居前5位的传染病为痢疾、病毒性肝炎、伤寒、麻疹、淋病,2000年以后则演变为病毒性肝炎、痢疾、肺结核、淋病、麻疹。无论如何变化,痢疾、病毒性肝炎、麻疹3种疾病始终保持在前5位中。[结论]丽江市传染病自90年代以来发病率呈平稳态势。疾病谱虽然发生了明显的变化,血源及性传播疾病发病率明显上升,但是肠道传染病、呼吸道传染病仍然占较大比重,传染病控制仍然是当前重要的公共卫生任务,应适时调整防病策略,加大控制力度,有效降低传染病发病率。
[Objective] To analyze and discuss the epidemic characteristics and trend of legal notifiable infectious diseases in Lijiang City from 1983 to 2007, and provide scientific basis for all levels of government to make prevention and control strategies. [Method] The epidemic situation information of epidemics in the whole city were collected over the years, and the time series and self-control were used. The epidemiological methods were used for statistical analysis. [Results] The epidemic situation of the whole city fluctuated between 143.98 and 3701.33 / 100,000 in 1983 and 2007. In the 1980s, the overall incidence showed a linear downward trend. The incidence of infectious diseases was dominated by intestinal infectious diseases and also showed a downward trend in all the years, with the proportion decreasing from 73.07% to 41.78%. Significant changes occurred in the spectrum of infectious diseases since 2000 The incidence of blood-borne and sexually transmitted diseases increased significantly, accounting for 26.97% of the total number of infectious diseases. Although the respiratory infectious diseases decreased significantly, the composition ratio did not change much. In the 1980s, the top 5 infectious diseases were dysentery, measles, pertussis, viral hepatitis and typhoid fever. The top 5 infectious diseases in the 1990s were dysentery, viral hepatitis, typhoid fever, measles and gonorrhea. After 2000, Viral hepatitis, dysentery, tuberculosis, gonorrhea, measles. No matter what changes, dysentery, viral hepatitis, measles three diseases remain in the top five. [Conclusion] The incidence of infectious diseases in Lijiang City has been in a steady state since the 1990s. Although the disease spectrum has undergone significant changes, the incidence of blood and sexually transmitted diseases increased significantly, but the intestinal infectious diseases and respiratory infectious diseases still account for a large proportion. The control of infectious diseases is still an important public health task and should be adjusted in time Prevention strategies to increase control efforts to effectively reduce the incidence of infectious diseases.
