摘要
目的了解新冠疫情暴发期间西安市无偿献血人群SARS-CoV-2抗体流行情况,为制订新冠病毒传播防制策略提供依据。方法收集西安市2020年1月1日~6月14日的健康献血者标本共3 623份,采用化学发光法对标本进行血清抗SARS-CoV-2抗体检测。并对比西安本土新型冠状病毒肺炎确诊病例数与西安无偿献血人群SARS-CoV-2抗体月流行率趋势的相关性。结果共检测3 623名西安市无偿献血人员,发现3例SARS-CoV-2抗体阳性者,流行率为0.083%(95%CI:0.00,0.18),最早出现新冠病毒血清阳性的献血者是在2020年2月4日。结论西安地区无偿献血者的抗SARS-CoV-2阳性率很低,符合西安当地疾病的流行情况。提示对献血者进行血清学检测,可以作为疫情监测的一种方式。
Objective To estimate the seroprevalence of SARS-CoV-2 infection among blood donors during the COVID-19 outbreak, in order to provide reference for formulating coping strategies.Methods A total of 3 623 samples of healthy blood donors in Xi′an from January 1 to June 14, 2020 were collected and tested by chemiluminescence microparticle immunoassays(CMIA). The correlation between the number of confirmed cases of COVID-19 in Xi′an and the monthly prevalence trend of SARS-CoV-2 antibody in Xi′an was also studied. Results Among the 3 623 blood donors, 3 were reactive by CMIA, with the seroprevalence rate of SARS-CoV-2 at 0.083%(95%CI:0.00, 0.18). The earliest yielding of SARS-CoV-2 in Xi′an was in February 4, 2020. Conclusion The SARS-CoV-2 seroprevalence rate in Xi′an is low, which is in line with the local prevalence status. It is suggested that serological detection of blood donors is a way to monitor the prevalence of COVID-19.
