2008～2010年开阳县伤寒、副伤寒监测结果分析

Analysis of results of typhoid and paratyphoid surveillance in Kaiyang,2008-2010

目的掌握开阳县伤寒、副伤寒疾病的流行情况,探寻危险因素,为提出有针对性的综合性防制措施提供依据。方法在开阳县选择既往发病较多的6个乡镇建立以全人群的伤寒、副伤寒病原菌监测系统,对就诊发热病例进行登记、采血作病原学检测,监测时间2008年5月～2010年8月。结果登记发热病例112 503例,采集血液标本8 529份,检出阳性病例92例,其中伤寒1例,副伤寒91例。病例以10～40岁人群为主,农民占确诊病例数的69.57%;体温在37.5～38.0℃的占52.17%,症状多以上感症状为主。结论开阳县流行的菌株主要为甲型副伤寒;加强对发热人群伤寒、副伤寒监测,早期发现、及时治疗病人是伤寒、副伤寒防控的重要措施。

Objective To ascertain the prevalence of typhoid and paratyphoid fever in Kaiyang and explore risk factors for both in order to provide a basis for targeted comprehensive control measures.Methods Six towns in Kaiyang with a higher incidence of typhoid and paratyphoid fever were selected,and a system was established to monitor bacteria causing typhoid and paratyphoid fever.Cases of fevers were registered and blood was collected for pathogen detection.Monitoring took place from May 2008 to August 2010.Results Blood samples were collected from 8 529 patients among 112 503 registered cases of fevers.Of these patients,92 tested positive,including 1 case of typhoid fever and 91 cases of paratyphoid fever.Patients were mainly ages 10 to 40,and farmers accounted for 69.57% of confirmed cases.Of the patients,52.17% had a temperature of 37.5-38.0 ℃.Many patients had multiple subjective symptoms.Conclusion The prevalent strain in Kaiyang was mainly Paratyphoid A.Enhancing surveillance of people with typhoid fever and paratyphoid fever,early detection,and timely treatment of patients are crucial to prevention and control of typhoid and paratyphoid fevers.
