Sero-positivity to EKV-1 and EKV-2.

A serosurvey for EKV-1 and EKV-2 was performed on Nigerian samples (n = 320). Cut-off values were based on the mean of US normals (n = 137) plus either 3xSD or 5xSD (SD = standard deviation).Sero-positivity to EKV-1 and EKV-2.本研究针对EKV-1与EKV-2，在尼日利亚的320份样本（n=320）中开展了血清流行病学调查。临界值的设定以137名美国正常人群（n=137）的均值为基准，分别叠加3倍标准差（3×SD）或5倍标准差（5×SD，其中SD为标准差（standard deviation））。针对EKV-1与EKV-2的血清阳性率。
