In a research paper published by CSIR (Council of Scientific and Industrial Research), it has come to light that people with AB and B blood groups are more susceptible to Covid-19 when compared to other blood groups.The paper further established that O blood group people are least affected and most of them remained asymptomatic or reported some very mild symptoms.
In another revelation, people who consume meat are more susceptible to the virus when compared to the vegetarians said the survey which is based on the nationwide seropositivity survey conducted by CSIR. The high fibre content in the vegetarian diet is said to be the one which makes the difference in response to immunity. Moreover, a fibre-rich diet is also anti-inflammatory which prevent post-infection complexities and even prevent the infection from manifesting itself.
The survey was conducted with a sample size of over ten thousand people across the country and analyzed by a group of 140 doctors. The survey also found that the highest number of infected came from the AB blood group, closely followed by the B blood group, while the O group people showed the lowest seropositivity.
Commenting on this survey by CSIR, senior physician Dr. S K Kalra said that this is merely a sample survey and not a peer-reviewed scientific research paper. Dr Kalra added that the survey’s inferences need to be taken with a pinch of salt, as without a scientific understanding of why there was a difference in the infection rates of people with different blood groups, it would be too hasty to say anything about the so-called better immunity of people with O blood group.
