Seroconversion in household members of COVID-19 outpatients



We read with interest the Article by Qifang Bi and colleagues, in which they reported a household secondary attack rate, as detected by repeated RT-PCR tests, of approximately 11%. We have found substantially higher attacks rates in western Norway through detection of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
