The Council of Scientific and Industrial Research (CSIR) has published a research paper indicating that people with AB and B blood groups were more susceptible to COVID-19 compared to other blood groups.
The research further said that people with 'O' blood group were the least affected by the virus and most of them remained asymptomatic or had very mild symptoms.
Additionally, the research report, which is based on a nationwide seropositivity survey conducted by CSIR, indicates that those who consume meat are more susceptible to COVID-19 than vegetarians.
With a sample size of over 10 thousand people countrywide, the data has been analysed by a group of 140 doctors. Dr Ashok Sharma, pathologist, Agra, said that everything depends on the genetic structure of a person.
It is possible that people with O blood group have a better immune response against this virus compared to AB and B groups, although this research merits further and detailed study. This, however, does not mean that people with O blood group can let go of all Covid prevention protocols, as people with O blood group are not completely immune to the virus and are developing complications too, he added.
