Several subsequent studies reported controversial results. We conducted a retrospective matched case-control study that aims to investigate the association between blood groups and the risk and\/or severity of COVID-19. We compared the blood groups distribution of 474 patients admitted to the hospital for COVID-19 between March 2020 and March 2021, to that of a positive control group of outpatients infected with COVID-19 and matched them for sex and age, as well as to the distribution in the general population. Three hundred and eighteen HC+ pairs with available blood group information were matched. The proportion of group A Rh+ in hospitalized patients (HC+) was 39.9% (CI 35.2%\u201344.7%), compared to 44.8% (CI 39.8%\u201349.9%) and 32.3% in the positive outpatient controls (C+) and the general population (C\u2212), respectively. Both COVID-19-positive groups (HC+\u2009and C+) had significantly higher proportions of group A Rh+ compared to the general population (p\u2009=\u20090.0019 and p\u2009<\u20090.001, respectively), indicating that group A Rh+ increases susceptibility to COVID-19. Although blood group A Rh+ was more frequent in the outpatients C+\u2009compared to the hospitalized group HC+, the association did not reach statistical significance, indicating that blood group A Rh+ is not associated with severity. There was no significant relationship between COVID-19 and other blood groups. Our findings indicate that blood group A Rh+ increases the susceptibility for COVID-19 but is not associated with higher disease severity.\n\n\n<\/p>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/static.hupso.com\/share\/buttons\/share-medium.png?w=640&#038;ssl=1\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"Journal of Medical Virology - 2021 - Kerbage - Impact of ABO and Rhesus blood groups on COVID\u201019 susceptibility and\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>"},"caption":{"rendered":"Early evidence from China suggested that blood groups may be involved in susceptibility to COVID-19.
