目的分析2006—2015年华亭县自然疫源及虫媒传染病的流行病学特征,为预防和控制该类传染病提供依据。方法采用描述流行病学方法,对2006—2015年华亭县自然疫源及虫媒传染病报告资料进行分析。结果 2006—2015年华亭县共报告乙类自然疫源及虫媒传染病4种141例,年平均发病率7.66/10万,病死率3.55%,发病率呈逐年上升趋势,不同年度发病率差异有统计学意义(χ~2=92.44,P<0.05);发病居前三位的传染病依次为布鲁氏菌病、流行性出血热、流行性乙型脑炎;除疟疾外,其他病种各乡(镇)均有报告,不同乡(镇)发病率差异有统计学意义(χ~2=148.96,P<0.05);各月均有病例发生,8月发病数最高(26例),10月最低(5例);男女性别比为2.13∶1,发病主要集中在40岁~年龄组,占报告总病例数的34.75%(χ~2=238.38,P<0.05);以农民为主、占报告总病例数的83.69%,不同职业差异有统计学意义(χ~2=89.22,P<0.05)。结论华亭县自然疫源及虫媒传染病总体呈逐年上升趋势,发病有明显的季节性和人群分布特征,今后应实施重点人群、重点区域、重点疾病、重点环节的防控策略,预防和控制疾病的发生和流行。
Objective To analyze the epidemiological characteristics of natural epidemic and insect-borne diseases in Huating County from 2006 to 2015, and provide the basis for prevention and control of such infectious diseases. Methods Descriptive epidemiological methods were used to analyze the reported data of natural epidemic and insect-borne diseases in Huating County from 2006 to 2015. Results From 2006 to 2015, Huating County reported a total of 141 cases of type B natural foci and insect-borne diseases, with an average annual incidence rate of 7.66 / lakh and a case-fatality rate of 3.55%. The incidence rate showed an upward trend year by year. The incidence rates in different years (Χ ~ 2 = 92.44, P <0.05). The top three infectious diseases were brucellosis, epidemic hemorrhagic fever and epidemic encephalitis. In addition to malaria, the other diseases The incidence of different townships (towns) was significantly different (χ ~ 2 = 148.96, P <0.05); all cases occurred in each month and the highest incidence in August (26 cases) , And the lowest in October (5 cases). The sex ratio of men and women was 2.13:1. The incidence mainly concentrated in the age group of 40 years and older, accounting for 34.75% of the total reported cases (χ ~ 2 = 238.38, P <0.05) Master, accounting for 83.69% of the total reported cases, the difference was statistically significant (χ ~ 2 = 89.22, P <0.05). Conclusion The natural foci and the zoonotic diseases in Huating County have been increasing year by year. The incidence is obviously seasonal and crowd distribution characteristics. In the future, prevention and control strategies should be implemented for key populations, key areas, key diseases and key links The occurrence and prevalence of disease.
