There are number of infectious diseases but some of them turn as epidemic whereas few other turn into pandemic. Now, India is dealing with second wave of COVID-19 pandemic. The number of deaths are increasing on a high note in the country. In the second wave of coronavirus, people are dying due to lack of oxygen.

Now, The Council of Scientific and Industrial Research (CSIR) has published a research paper which suggested that people with AB and B blood groups are more vulnerable to the dangerous coronavirus compared to other blood groups. It is said that people with O blood group were the least affected by the virus. The research report is based on nationwide seropositivity survey conducted by CSIR.

Another finding is that non-vegetarians are more susceptible to COVID-19 than vegetarians. The high fiber content in vegetarian diet helps prevent post-infection complications.

In the same way, there are families where in everyone had tested positive for COVID-19 except one member.
