Blood group O associated with a decreased risk of Covid infection

Development of Covid-19 is associated with age, sex, and co-morbidities, such as cardiovascular diseases, although severe disease is not limited to these risk groups. All things considered, 4.5 less days in the intensive-care unit than those with Type An or AB blood.

Scientists have been investigating a potential link between blood type and vulnerability to Covid-19 for many months, and this latest evidence supports previous findings.

Another study, done in Spain compared the outcomes of 1900 severely ill COVID+ patients with 2000 healthy, non-sick patients.

Among the SARS-CoV-2 individuals, considerably fewer group O individuals were found, conversely, more A, B, and AB individuals were noted.

Researchers have created, unexpectedly, a score that can precisely anticipate which patients will build up an extreme type of Covid-19. The study suggests that people with blood types A, B, or AB may be more likely to be infected with Covid-19 than people with type O. For such blood type, the risk of developing severe symptoms, including organ failure, is also reduced.

The researchers did not find any significant difference in rate of infection between A, B, and AB types.

However, both studies' authors note several limitations that warrant consideration, and suggest further research to confirm these findings and enhance scientists' understanding of blood type association to Covid-19 severity.

A progressing research team implied a connection between coronavirus risk and blood type.

Blood group A and B glycosyltransferases also affect glycosylation in a large number of cell types, including epithelial cells in the respiratory tract and shed viral particles.

It contains the blood of people recovering from the epidemic Antibodies Moving against the virus, "plasma" technologies have shown a great benefit Corona patients treatment.

Previous studies have indicated similar results in patients with blood type O.

"Individuals with O blood type are between 9-18% percent less likely than individuals with other blood types to have tested positive for COVID-19, according to the data", a company statement said at the time.

And in March, an investigation of more than 2,100 coronavirus patients in the Chinese urban areas of Wuhan and Shenzhen likewise found that individuals with Type O blood had a lower danger of disease.

Distribution of blood groups was compared with data from non-tested individuals.

Despite all this, Mypinder Sekhon, a co-author of the Vancouver research, said that the link is still insubstantial. "And even if you're blood type O, you're not free to go to the pubs and bars".
