Coronavirus: People with this blood group least vulnerable to COVID-19

1,195 New COVID-19 Cases, 14 More Virus-Related Deaths Reported, State Health Officials Say

A growing body of evidence suggests those who have blood type O may be less likely to contract coronavirus and typically experience less severe symptoms when they do come down with the illness. The findings also showed that blood groups "A" and "AB" associated with an increased risk of severe clinical outcomes of COVID-19 infection. Canadian researchers suggest those with A or AB blood are more likely to suffer lung damage due to COVID-19.

This lends credence to the fact that people with blood type A, B and AB, may be more at risk of getting infected than those with blood type O.

Which blood types put coronavirus patients in danger?

Further investigations on the mechanism of the different susceptibility to COVID-19 between blood group A and O individuals are needed and regardless of your blood type, you need to follow public health recommendations. The findings indicate why the coronavirus is lethal for some and not so for the others.

The researchers also point out that they did not find any significant difference in rate of infection between A, B, and AB blood types. A study at the University of Southern Denmark says that it is very important to consider the proper control group because blood type prevalence may vary considerably in different ethnic groups and different countries.

The first of the two studies saw scientists look at health registry data from more than 473,000 people in Denmark who tested for Covid-19 and compared it to a control group of more than 2.2 million people from the general population, accounting for nearly 40 percent of the total Danish population.

People with blood groups "A" or "AB" appear to exhibit greater Covid-19 disease severity than people with blood groups "O" or "B", according to a separate retrospective study. They found that patients with blood groups A or AB were more likely to need mechanical ventilation, with 84 percent of A or AB patients requiring mechanical ventilation compared to 61 percent of O or B patients.

Also this summer, the genealogy website 23andMe.com released data they collected from 750,000 participants who identified they have tested positive for COVID-19.

In this study, researchers investigated data from 95 critically ill, hospitalised Covid-19 patients in Vancouver, Canada, who were admitted to the intensive care unit (ICU) between 1 March 2020 and 28 April 2020.

People with blood group O positive can donate blood only to people with positive blood groups like A+, B+, O+, AB+.
