A team of European scientists has found that two genetic variations may show who is more likely to get very sick and even die from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Further, they found a link to blood type, suggesting that some people are predisposed to COVID-19 severe disease.
The study findings, published in The New England Journal of Medicine, shed light on why some people have a higher risk of being infected with the coronavirus and developing worse symptoms.
In three completely separate studies, researchers from Columbia University, Iran's Mazandaran University of Medical Sciences, and various Chinese institutions all arrived at similar findings.
