目的了解涉县夏季正常人群和发烧样病人中盖塔病毒感染状况。方法采用抗体捕捉ELISA方法检测盖塔病毒IgM抗体和间接ELISA方法检测IgG抗体。结果正常人群IgM抗体阳性率为0.30%(1/300);IgG抗体阳性率为16.30%(49/300)。发烧样病人盖塔病毒IgM抗体阳性率0.63%(2/317)。结论正常人群对盖塔病毒易感,感染率较高,为16.67%;夏季发烧样病人中也存在盖塔病毒感染,但感染率比例很低。这具有重要的流行病学意义。
Objective To investigate the prevalence of captive virus infection in summer in normal population and fever-like patients in Shexian County. Methods Antibody-capture ELISA was used to detect IgM antibodies to captive virus and indirect ELISA to detect IgG antibodies. Results The positive rate of IgM antibody in normal population was 0.30% (1/300). The positive rate of IgG antibody was 16.30% (49/300). The positive rate of IgM antibody in patients with fever-like virus was 0.63% (2/317). Conclusion The normal population is susceptible to Geeta virus with a high infection rate of 16.67%. Gevaita virus infection is also found in summer fever-like patients, but the infection rate is very low. This has important epidemiological implications.
