Seems like most of you are bored staying indoors these days. Am I Right?

Well, we all know the reason. It’s the CoronaVirus that is extensively prevalent nowadays and has already taken over 9000 lives. And know why this article comes up here? It’s because researchers have brought something that puts us in thought. Without wasting more time, let’s dive in to find out what we have!!

The news is that researchers have found a particular blood type to be more susceptible to the new coronavirus. Let’s find out to what extent this value is true?

The information comes from a study. So don’t be tense about it. It’s not yet been peer-reviewed and is available on the preprint server medRxiv.  Chinese researchers undertook a study and focused on 2,173 patients with COVID-19 from three hospitals in Wuhan and Shenzhen.

They looked at the distribution of blood types in the normal population in each area and then compared it to their sample of patients with the virus, again in each area.

The researchers wrote in their paper that Meta-analyses on the pooled data showed that blood group A had a significantly higher risk for COVID-19 compared with non-A blood groups. They also added that blood group O had a significantly lower risk for the infectious disease compared with non-O blood groups.

Even though they put forward this in their paper, it’s not an all-or-nothing result. Now let’s move on with the statistics.

The normal population in Wuhan has a blood type distribution of 31 percent type A, 24 percent type B, 9 percent type AB, and 34 percent type O. Those with the virus, by comparison, were distributed: 38 percent type A, 26 percent type B, 10 percent type AB, and 25 percent type O. Similar differences were observed in Shenzhen.

It doesn’t mean that people with O blood groups are immune and also not all people with A blood group will get the virus.

But this raises another fascinating topic – how our blood types can change the way we are affected by certain viruses is interesting.

This is important for things like blood transfusions because our immune system can see the other types as intruders. We already know that some viruses – for example, noroviruses – directly exploit these differences in blood cell antigens.

“This difference in susceptibility [to norovirus] has an interesting consequence,” microbiologist Patricia Foster writes for The Conversation.

The authors suggest that the virus may have to do something with the anti-A antibodies that both type B and type O have. There’s a vaccine being trialed in humans; many are doing everything they can to flatten the curve; and while the pandemic is stopping the world in its tracks, communities are swapping supplies and helping those in need.
