They also found that while people with blood types A and AB didn't have longer overall hospital stays than those with types O or B, on average, they were in intensive care longer, which may indicate more severe COVID-19.

Researchers from the National Institute for Health Research who reviewed the available evidence said long COVID could actually be four different syndromes.

Meanwhile, others may have suffered permanent organ damage.

These were the details of the news Fresh Blood Test Correctly predict which COVID-19 patients will develop severe. for this day.


The team has researched almost half a million people in the Netherland tested for COVID-19 between the period of late February and late July. A study published in July looking at patients in five major hospitals in the state of MA found that people with blood type O were less likely to test positive for COVID-19 than those with other blood types. By contrast, 44.4 percent of type A tested positive, while in the wider Danish population that blood type makes up 42.4%. Also, they are less prone to get severely sick even if they get infected.

The study results suggest that people with blood types A, B, or AB may be more likely to be infected with COVID-19 than people with type O. The researchers did not find any significant difference in rate of infection between A, B, and AB types.

Research is correlating the idea that people with blood group O are on a little advantage during this pandemic.

These new outcomes are similar conclusions about Type O blood detected in earlier research, generating a clearer picture of one specific coronavirus risk aspect.


Two studies in the Blood Advances journal show that people with type A blood represented 6% more of the COVID-19 patient population than their type O counterparts.

The researchers examined data from 95 critically ill COVID-19 patients hospitalised in Vancouver. People having O blood group have neither antigen.

"I don't think this supersedes other risk factors of severity like age and co-morbidities and so forth", Dr Sekhon, a clinical assistant professor in the Division of Critical Care Medicine and Department of Medicine at the University of British Columbia, told CNN.

It's important to emphasize that the type of reduction in risk achieved with appropriate physical distancing, wearing a mask, and hand hygiene are significantly better than depending on your blood group for protection, so people with blood type O should not be complacent about public health advice. "And if you're blood group O, you're not free to go to the pubs and bars".
