Can blood type determine your risk of developing Covid-19?

Blood groups types prone to covid

In the last few months, many researches have indicated that a person’s age and underlying health conditions can increase the risk of developing severe symptoms of Covid-19. Now, some of the researches are suggesting that the blood type of a person can also determine his risk of developing the deadly virus.                    

Some researchers have found that many of the patients who had developed severe symptoms of Covid-19 possessed the same variant on a gene that determines a person’s blood type. They found that blood type A was linked with a 50 per cent increase in the chances of developing Covid-19.

A separate preprint study conducted by the researchers in China had found similar results. They found that blood type A was associated with a higher risk of death from Covid-19 among the 2173 patients infected by the virus. It also found that people with blood type A are more likely to get the virus in the first place, compared to those with 0 type blood.

However, there are several other factors and not just the blood type that could determine the risk of certain individuals developing Covid-19, say medical practitioners and health experts. The researchers have adjusted factors like age, sex, body mass index, ethnicity and other health conditions to find the relation in this regard.  

Genetics do play a vital role in determining who is more likely to be infected with the virus. Different blood types have different features, but all these findings related to Covid-19 are preliminary at this juncture. One cannot conclude anything as more and more findings are surfacing with contrasting results.

Even if the research is taken as a yardstick that the people with type O blood have a lower chance of developing Covid-19, it doesn’t make them invincible. The guidelines still remain the same for everyone and it is important to follow the precautionary measures to safeguard yourself and your family from this deadly virus.
