Analysis on the surveillance data of typhoid fever and paratyphoid fever in Yuhuan county, Zhejiang province from 2005 to 2007

目的通过对2005-2007年浙江省玉环县伤寒副伤寒疫情资料及监测结果的分析,了解伤寒流行情况及监测效果。方法将2005-2007年全县伤寒副伤寒监测资料和疫情资料录入Excel数据库,运用SPSS软件进行统计分析。结果全县病原分离的菌型以甲型副伤寒沙门菌为主,占91.70%,3年来疫情呈下降趋势。疑似病例监测阳性率平均为16.86%,发现率逐年提高,平均为66.59%;重点人群、密切接触者、恢复期带菌率、历史病例带菌率均较低;外环境和食品中未检出阳性。结论加强监测,早期发现病例,规范治疗是目前控制伤寒副伤寒的主要措施。

Objective The present study was conducted to determine the prevalence of typhoid fever and paratyphoid fever in Yuhuan county and evaluate the surveillance system based on local epidemic situations and surveillance data between 2005 and 2007. Methods Epidemic situations and surveillance data of typhoid and paratyphoid fever in Yuhuan county between 2005 and 2007 were recorded with Excel software and analyzed with SPSS software package. Results Salmonella paratyphosa isolates was the dominant pathogen responsible for the diseases, which accounted for 91.7% of locally isolated strains. In contrast to the decreasing epidemic situations in the recent 3 years; average incidence of surveilled suspected cases was 16.86% and increased annually with a mean rate of 66.59%. The detection of bacteria in the interested population, individuals with close contact with patients, patients in restorative stage and previous patients was rare. Nothing positive was found in the external environments and foods. Conclusion Reinforcement of surveillance, early detection of cases, and standard treatment are currently major measures for the control of typhoid fever and paratyphoid fever.
