The nucleic acid and the capsid are collectively called a nucleocapsid.

Some virions have a phospholipid membrane derived from the host cell called an envelope, which surrounds the nucleocapsid.

有些病毒粒子具有来源于宿主细胞的磷脂膜，称为囊膜；囊膜包绕着核衣壳。

Similar to previous diagnostic assays for severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), it has three nucleocapsid gene targets and a positive control target.

与之前对严重急性呼吸系统综合症冠状病毒 (SARS-CoV) 和中东呼吸系统综合症冠状病毒 (MERS-CoV) 的诊断分析类似， 它具有三个核衣壳基因靶点和一个阳性对照靶点。
