Household Transmission of Severe Acute Respiratory Syndrome Coronavirus-2 in the United States

BACKGROUNDThe evidence base for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is nascent. We sought to characterize SARS-CoV-2 transmission within US households and estimate the household secondary infection rate (SIR) to inform strategies to reduce transmission. METHODSWe recruited p...
