New studies uncover something unique that could influence your Covid hazard

Are people with'O blood group less vulnerable to COVID-19 infection? Here's what new study suggests Score predicts severe COVID in patients

Among the COVID-19 positive, they found fewer people with blood type O and more people with A, B, and AB types. Patients with blood types A and AB did not have longer hospital stays than those with types O or B, but they did experience longer intensive care unit stays, which may signal greater COVID-19 severity. The specialists found that of those 95 sick patients, 84% with Type A or Type AB blood ended up requiring mechanical ventilation, contrasted with 61% of those with Type O or Type B blood.

The levels of both of these molecules are altered in patients with severe COVID-19.

The study performed a retrospective cohort analysis of all Danish individuals tested for SARS-CoV-2 between 27 February 2020 and 30 July 2020, with a known ABO and RhD blood group, to determine the influence of common blood groups on virus susceptibility.

"This finding may suggest that such patients benefit equally from ICU admission and thus the threshold for admission should be calibrated accordingly in any future COVID-19 surge", the research team wrote.

A study in June looking at patients in Italy and Spain found that blood type O had a 50 percent reduced risk of severe coronavirus infection (i.e. needing intubation or supplemental oxygen) compared to patients with other blood types.

The second research is based on almost 95 people from Vancouver, Canada who had tested positive for the virus.

The researchers also point out that they did not find any significant difference in rate of infection between A, B, and AB blood types.

As CNN reports, two studies published on Wednesday recommend that individuals with Type O blood are less inclined to get COVID-19, and may likewise have a lower possibility of becoming gravely sick on the off chance that they are contaminated. People having O blood group have neither antigen.

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

Despite all this, Mypinder Sekhon, a co-author of the Vancouver research, said that the link is still insubstantial. Researchers observed lung and kidney damage, and in future studies, they want to tease out the effect of blood group and COVID-19 on other vital organs. "And even if you're blood type O, you're not free to go to the pubs and bars".
