People with blood type ‘O’ unlikely to contract COVID-19: Study

A new research has stated that the people having blood group ‘O’ have less chance of contracting coronavirus.

According to research, the people with blood group ‘A’ might be more exposed as compared to blood group ‘O’. The researchers have said that genetics plays in susceptibility to contracting the virus, and some more specifically have linked the role played by blood type.

There is one aspect of COVID-19 virus that has puzzled scientists and doctors across the world. The question is when infected with COVID-19 virus do some patients display mild to moderate symptoms, whereas other patients develop severe symptoms that can prove fatal?

According to the study while looking at only exposed individuals, the ones with O blood group were 13-26 per cent less likely to test positive for COVID-19 virus. Also if considering healthcare and other front line workers among those exposed to the virus.

It was found that blood group O is more protective, but the proportion of cases within the strata is higher. The study also found that differences in rhesus factor (blood group + or -) did not affect whether the blood type was protective against COVID-19 virus. Moreover, this was not a factor in the severity of cases.

The study is still undergoing, with scientists yet to configure at what the genetic data actually indicates. So far, 750,000 participants have been studied by the company, and has plans to include 10,000 more participants who have been recently hospitalized and diagnosed with COVID-19 infection.
