Many studies have been published consistently with suitable hypotheses about how infectious the virus is, who is well on the way to be contaminated, how risky the virus can be for specific kinds of individuals, etc. Early on, a few of those studies demonstrated that one’s blood type could affect the severity of the ailment, and this week, two additional studies upheld up that declaration.

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.

The first study, from Denmark, analyzed information from 473,654 who were tested for COVID-19 from February to July. 7,422 of those tests returned positive, and of those people, 38% had Type O blood and 44% had Type A blood. In an a lot bigger information sample of over 2.2 million individuals in Denmark who were not tested for the virus, 42% had Type O blood and 42% had Type A blood. These outcomes appear to show that notwithstanding people with Type O and Type A blood being equitably part among everyone, Type O is less powerless against the virus.

Another study, which took a gander at 95 fundamentally sick COVID-19 patients hospitalized in Canada, arrived at comparable conclusions. 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.

“As a clinician … it is at the back of my mind when I look at patients and stratify them,” Dr. Mypinder S. Sekhon, an intensive care physician at Vancouver General Hospital and author of the Canadian study, told CNN. “But in terms of a definitive marker, we need repeated findings across many jurisdictions that show the same thing. I don’t think this supersedes other risk factors of severity like age and co-morbities and so forth. If one is blood group A, you don’t need to start panicking. And if you’re blood group O, you’re not free to go to the pubs and bars.”

The two significant takeaways here are that there is as yet unquestionably more information needed before any definitive conclusions can be drawn from this research, and that regardless of whether ABO blood type assumes a function in the virus’s ability to contaminate somebody or cause them serious harm, it’s as yet not a sufficient distinction to influence pandemic best practices for anyone.
