目的 对2004-2006年舟山市定海区法定传染病报告发病进行流行病学监测分析.方法 采用描述流行病学研究方法.结果 3年法定传染病累计报告发病19种5932例,年均报告发病率为532.73/10万,年均报告死亡率为0.09110万.发病分类构成显示,血源及性传播传染病占46.93%,梅毒、乙型肝炎呈逐年上升,淋病则反之;肠道传染病占38.25%,其中60.33%为感染性腹泻病,且发病有上升趋势,痢疾发病2006年比2005年下降25.50%;呼吸道传染病占14.50%,肺结核发病呈逐年上升,流行性腮腺炎存在常年散发情况;自然疫源及虫媒传染病以输入性疟疾发病为主.结论 法定传染病网络直报对及时发现暴发性或聚集性疫情,及时采取应急防制措施有着十分重要的作用.同时,要进一步完善网络直报跨年度病例统计,提高评价传染病实际发病水平的准确性.
Objective The study was conducted to analyze the reported incidence of notifiable infectious diseases based on the epidemiological surveillance in Dinghai District Zhoushan City from 2004 to 2006. Methods The descriptive epidemiological approach was employed. Results Cumulatively 19 kinds of 5932 cases of statutory infectious disease were reported in three years, with an average annual reported incidence of 532.73/lakh, the average annual reported mortality 0.09/lakh. As was indicated from the classification of morbidities, blood and sexually transmitted diseases accounted for 46.93%; syphilis and hepatitis B had an yearly increasing incidence contrary to gonorrhea; gastro-intestinal diseases accounted for 38.25%, 60.33% of which constituted infectious diarrhea and their incidence was rising; the incidence of dysentery declined 25.50% in 2006 compared with that in 2005; respiratory diseases accounted for 14.50%, the incidence of tuberculosis increasing year after year; perennial sporadic incidence of mumps was observed; imported malaria was the predominant arbovirus disease. Conclusion Direct network report of notifiable infectious diseases plays an essential role in facilitating the timely detection of outbreak or clusters of diseases and timely prevention and control measures. Meanwhile, multiple-year statistics of network direct report cases should be further improved to conduct precise estimation of the actual incidence of infectious diseases.
