Misleading: A Connection Between Covid-19 and Blood Type

A research paper published in March raised a debate on social media claiming that there is a link between the blood type and COVID-19. Some users claimed that patients with blood types B and AB who received a test were more likely to test positive and blood type O was less likely to test positive. Rh+ patients were more likely to test positive.



Others claimed that the risk for COVID-19 was 45% higher for people with type ِA blood than those with other blood types. It appeared to be 35% lower for people with type O.
