文章在此： https://www.nature.com/articles/s41591-020-0897-1 Abstract We report acute antibody responses to SARS-CoV-2 in 285 patients with COVID-19. Within 19 days after symptom onset, 100% of patients tested positive for antiviral immunoglobulin-G (IgG). Seroconversion for IgG and IgM occurred simultaneously or sequentially. Both IgG and IgM titers plateaued within 6 days after seroconversion. Serological testing may be helpful for the diagnosis of suspected patients with negative RT–PCR results and for the identification of asymptomatic infections.

樣本都是重症住院的患者，14%是加護病房的患者，其他的樣本住院的median天數是五天，康復的病人都有抗體，不過數量不一。.
之前还有报道认为感染早期抗体水平高反而容易是重症。冲突可能是由于这个研究都是在重症病人
这个可以根据病毒变异速度推测
是綜和其他冠狀病毒的例子來判斷，除非這病毒跟其餘以前已知的同類型病毒完全不同
推测是一回事，这个是可能性。但是总要验证之后才有结论吧。
就像一般病毒无症状者不会传染，但这个病毒的无症状者传染性一点不差。
好消息我還是願意信的，畢竟成天恐慌緊張也會降低免疫力
