New studies uncover something unique that could influence your Covid hazard

The findings suggest that people with A, B or AB blood may be more likely to be infected with COVID-19 than people with type O blood.

Dr. Amesh Adalja, a senior scholar at Johns Hopkins University, told CNN that the two new studies give "more converging evidence that blood type may play a role in a person's susceptibility to Covid infection and their chance of having a severe bout of Covid-19".

Based on the changes in the ratio of these two molecules over time, the researchers developed a point system where each 1-point increase was associated with 5.6 times increased odds for a more severe outcome.

The study performed a retrospective cohort analysis of all Danish individuals tested for SARS-CoV-2 between 27 February 2020 and 30 July 2020, with a known ABO and RhD blood group, to determine the influence of common blood groups on virus susceptibility.

Both new observations came out Wednesday in the journal Blood Advances. They found that patients with blood groups A or AB were more likely to require mechanical ventilation, suggesting that they had greater rates of lung injury from COVID-19.

It's important to emphasize that the type of reduction in risk achieved with appropriate physical distancing, wearing a mask, and hand hygiene are significantly better than depending on your blood group for protection, so people with blood type O should not be complacent about public health advice. However, they did find that only 61% of the patients with Type O or B blood needed a ventilator, compared to the patients with Type A or AB i.e. 84% while, they were also more prone to need dialysis, which means these patients have more risk of organ failure. According to the news in Scitechdaily, there was no such score for COVID-19 until this study.

Distribution of blood groups was compared with data from non-tested individuals. Of those, 38.4 percent had blood type O, while other research indicates that blood type makes up about 41.7 percent of the population. Also, they are less prone to get severely sick even if they get infected.

Notwithstanding elevated levels in blood, utilizing just IL-6 estimations as a Covid-19 prognostic apparatus is impeded by a few variables.

The Chinese team urged medics and governments to consider blood type differences when treating patients with the virus and helping prevent the spread of the disease.

There are four main blood groups - defined by their numbers of antigen and antibody proteins.

Research is correlating the idea that people with blood group O are on a little advantage during this pandemic.
