A couple of studies suggest that people with blood type O may have less risk of catching COVID-19, or suffering severe illness.
If you have blood type O, be thankful. Some studies suggest that people with blood type O have less risk of catching COVID-19. If they do get sick, they’re also less likely to suffer severe illness. These studies might also prove that COVID-19 depends on your blood type. However, experts say that they need to do more research.
Blood Type and COVID-19: Denmark
CNN reports that Danish researchers did one of these studies. In this study, they looked at 7,422 people with COVID-19. Among the 7,422 people, only 38.4% of them had blood type O. People with this blood type also made up 41.7% of the 2.2 million people who did not get tested.
On the other hand, 44.4% of people with blood type A caught the virus. These people also make up. 42.4% of the greater Danish population.
Blood Type and COVID-19: Canada
Another study in Canada looked at 95 patients critically ill with COVID-19. The researchers found that 84% of the patients with blood type A or AB needed artificial oxygen. On the other hand, 61% of the patients with blood type O or B require the same.
Moreover, the study also found that patients with blood type A or AB stayed longer in the ICU. Their median was 13.5 days. Meanwhile, the patients with blood type O or B had a median of nine days.
What Do These Blood Type Studies Mean?
Most Americans have the O and A blood types. Generally, people also fall under these types: A, B, AB, or O. The Danish team also said that you don’t have to worry about the link between blood type and COVID-19. Researchers also have to do more studies to confirm the connection.
