目的了解邢台市流行性感冒(流感)的流行趋势、病原学变化规律,为以后流感防控工作提供科学依据。方法哨点医院对流感样病例(ILI)进行监测,并按要求采集ILI咽拭子标本运送至流感监测网络实验室,流感监测网络实验室在24 h内采用实时反转录聚合酶链反应(Real-time RT-PCR)法进行核酸检测,并完成流感病毒的分离鉴定。结果 2013年邢台市流感监测哨点医院共监测门、急诊就诊病例102 810例,ILI 1 873例。病例以0岁~年龄组为主(30.54%),60岁~年龄组最少(10.84%),其中0岁~和25岁~年龄组所占比例较大。2013年共检测流感样病例标本938份,核酸阳性70份,阳性率7.46%。其中B型流感病毒核酸阳性1份,A型H3阳性27份,新A型H1N1阳性41份,A型未分型1份。结论邢台市2013年流感均为散发,无流感疫情暴发。2013年邢台市流行的流感病毒有新A型H1N1、A型H3、B和A型未分型,其中以新A型H1N1流感流行为主。
Objective To understand the epidemic trend and pathogeny of influenza in Xingtai City and provide a scientific basis for future prevention and control of influenza. Methods The sentinel hospital monitored influenza-like illness cases (ILI) and collected ILI throat swab samples as required to be sent to the Influenza Surveillance Network Laboratory. Real-time reverse transcription polymerase chain reaction Real-time RT-PCR method for nucleic acid detection, and complete the identification of influenza virus. Results In 2013, a total of 102 810 cases of emergency visits and 1873 cases of ILI were monitored in the sentinel surveillance hospitals of Xingtai City. The cases were mainly 0 years old ~ age group (30.54%), the least was 60 years old ~ age group (10.84%), of which 0% ~ 25 years old age group accounted for a large proportion. In 2013, a total of 938 samples of influenza-like illness were detected, with 70 positive samples showing a positive rate of 7.46%. Among them, 1 was positive for influenza B virus, 27 for type A H3, 41 for new type A H1N1, and 1 for type A non-typing. Conclusion All of the flu in Xingtai City was distributed in 2013, with no flu outbreak. In 2013, the most popular influenza viruses in Xingtai City were new type A H1N1, type A H3, type B and type A non-typed ones, of which the new type A H1N1 flu prevailed.
