Serious symptoms of Covid-19 can be blood type related.

Covid-19 symptoms and blood type may be related. This comes from two recently published new studies that suggest that people with type O have a lower risk of developing the disease, while people with blood types A and AB may develop more severe symptoms.
The conclusion was published in the magazine this Wednesday The blood advances, from the American Society of Hematology, and was obtained from two studies.

One of the studies compared data from 473,000 people tested in Denmark with information from another 2.2 million people. Among patients who tested positive for Covid-19, the researchers found fewer people with blood type O and more people with types A, B and AB.

Findings are backed by another study based on data from 95 patients with severe symptoms with Covid-19 who were hospitalized in Vancouver, Canada.

In this study, too, the researchers came to the conclusion that patients with blood groups A or AB are more likely to need mechanical ventilation, i.e. have higher lung injury rates from the new coronavirus.

“We have observed this damage to the lungs and kidneys and intend to investigate the effects of the relationship between blood types and Covid-19 on other vital organs in future studies,” said the study author, Mypinder S. Sekhon, of the University of British Columbia, Canada.
