COVID-19 patients who have Type A blood are more likely to have severe disease, while those with Type O are less likely.

There is limited data available based on a couple of studies, and independent research into it from around the world is currently unavailable.

There is limited data available based on a couple of studies, and independent research into it from around the world is currently unavailable.In June 2020, some European scientists found that people with Type A blood had a 45 percent higher risk of contracting COVID-19 and respiratory failure than people with other blood types, with Type O having a 35 percent risk. The study does not prove the linkage but confirms the March 2020 report from China that the blood type and the disease have a severity connection. Dr. Parameswar Hari, the blood specialist at the Medical College of Wisconsin, said that most of them discounted the Chinese report because it was a crude study. It was the first observation of the association between blood type and COVID-19 susceptibility.

Also, the New European study seems to validate those findings.

However, peer-reviewed research and monitoring from other parts of the world are necessary to verify whether various blood types affect the risk of severe COVID-19 infection.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
