Influence of ABO and Rh Blood Groups on COVID-19 Outcomes

摘要

Population-based study finds lower chances of SARS-CoV-2 infection and severe COVID-19 in persons with O and Rh-blood. A range of studies have suggested that blood group and risk for severe COVID-19 are linked. Using a national database between 2007 and 2019 in Ontario, Canada, investigators analyzed the proportions of persons with SARS-CoV-2 infection and severe COVID-19 for whom blood group information was available.
