New research shows blood group plays an important role in protecting against the coronavirus. The preliminary data collected from a DNA testing company shows some people are at a lower risk of testing coronavirus positive due to their particular blood group.
23andMe is a DNA testing company that conducted a recent study on the spread of coronavirus among individuals of different blood groups. The researchers found that O blood type individuals have 18 percent less risk of getting infected with the novel coronavirus.
The study also suggests that the people with this particular blood type have 26 percent less chance to contract the virus upon exposure. The research team conducting the study said that this study implies a significant relationship between blood group determining genes and coronavirus.
The study included nearly 750,000 participants and 10,000 of these participants were coronavirus positive.
The findings of the study show that most of the O blood group individuals who came in contact with the virus showed less rate of infection. This group includes health professionals in hospitals who were at 13 to 26 percent less risk of testing positive for the virus.
Out of those people who were exposed to the virus at some point, 3.2 percent of individuals tested positive had O blood type. Blood type A coronavirus positive people were 3.9 percent, people with B blood type were 4 percent while with AB blood type, 4.1 percent of individuals were tested positive for the virus.
The findings of this study are not peer-reviewed yet nor published in a scientific journal. The researchers found that a variant in the ABO blood group determining gene lowers the risk of coronavirus infection. However, this study is not fully approved by the scientific community yet.
23andMe blog published a statement saying that their research team is trying to study how different people contract the coronavirus. The company is looking forward to publishing their findings to help the scientific community.
This is not the first time when researchers found the link of blood group with Covid-19. Another study conducted earlier in March in China showed similar results. The findings showed that A blood type of people was more likely to get infected as compared to other blood groups.
The recent study indicates comparative results that the O blood type people are less likely to contract coronavirus as compared to the other blood groups. A team of researchers from Italy and Spain also found similar results upon studying the prevalence of coronavirus in different blood type individuals.
Another research conducted by Columbia University Irving Medical Center in New York City shows that there is a 33 percent more chance for A positive and A negative blood group individuals to be coronavirus positive.
These findings indicate the relationship between blood group type and coronavirus which is significant in the spread of the virus.
Currently, there are nearly 1.9 million confirmed coronavirus positive cases in the US. New findings of the novel coronavirus will help better understand the spread of the virus. Also, it will pave the strategy to fight against this global pandemic.
