Significance of serology testing to assist timely diagnosis of SARS-CoV-2 infections: implication from a family cluster

Emerging Microbes and Infections, 2020
Confirmative diagnosis of SARS-CoV-2 infections has been challenged due to unsatisfactory positive rate of molecular assays. Here we identified a family cluster of SARS-CoV-2 infections, with five of six family members were SARS-CoV-2-specific ...
