A fitness coach and a social media influencer who thought that the coronavirus or COVID-19 does not exist has died after contracting the deadly disease on a trip to Turkey.
People with blood groups "A" or "AB" appear to exhibit greater Covid-19 disease severity than people with blood groups "O" or "B", according to a separate retrospective study. As reported NBCNews, scientists agree that people with the second blood group ("A") are more vulnerable to COVID-19. Of those, only 38.4% had blood type O - despite people with that blood type making up 41.7% of the roughly 2.2 million untested people in the population. "It is very important to consider the proper control group because blood type prevalence may vary considerably in different ethnic groups and different countries", said study author Torben Barington from the University of Southern Denmark. The degrees of both are adjusted in serious Covid-19 patients.
The scientists collected data from the Danish health registry data of over 473,000 people who had tested positive for the novel coronavirus.
"The Dublin-Boston score is effectively determined and can be applied to all hospitalized Covid-19 patients", said RCSI Professor of Medicine Gerry McElvaney, the investigation's senior creator and a specialist in Beaumont Hospital. People with O-blood are also capable of donating red blood cells to any other type.
Your blood group depends on the presence or absence of proteins called A and B antigens on the surface of RBCs, a genetic trait inherited from your parents.
A total of 3,299 new COVID-19 cases and 28 deaths were reported in Delhi on Sunday, taking the total number of novel coronavirus cases to 3,31,017 in the national capital. People having O blood group have neither antigen.
It was also found that more patients with groups A and AB needed dialysis for kidney failure.
Despite all this, Mypinder Sekhon, a co-author of the Vancouver research, said that the link is still insubstantial. However, they can only receive O negative blood. He said "I don't think this substitutes other risk factors of severity like age and comorbidities and so forth".
There was a slight but statistically significant difference in blood group distribution between the SARS-CoV-2 individuals and the reference population.
