Household transmission of SARS-CoV-2: a prospective observational study in Bosnia and Herzegovina, August-December 2020.

ABSTRACT: The secondary attack rate (SAR) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was estimated, and the risk factors for infection among members of households with a coronavirus disease 2019 (COVID-19) index case were identified to inform preventive measures.
