Blood Type, Genetics Could Impact Odds for Severe COVID-19: Study

HealthDay ReportersTHURSDAY, June 18, 2020 (HealthDay News) -- A person's genes and blood type may help determine their odds for a nastier form of COVID-19, should they get infected with the new coronavirus, a new genetics study finds.

Published online June 17 in the New England Journal of Medicine, the research helps confirm earlier, more anecdotal evidence that blood type was tied to better or worse illness.

Now a team of European researchers have found that people with blood type A had a 45% higher risk of catching coronavirus and developing "COVID-19 with respiratory failure," compared to people with other blood types. On the other hand, people with type O blood had a 35% lower risk for this more serious form of COVID-19.

There are four main blood types: A, B, AB and O.

Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.

Scientists Link Covid-19 Risk to Genetic Variations

Why do some people infected with the coronavirus suffer only mild symptoms while others become deathly ill?

Geneticists have been scouring our DNA for clues. Now, a study by European scientists is the first to document a strong statistical link between genetic variations and Covid-19, the illness caused by the coronavirus.

Variations at two spots in the human genome are associated with an increased risk of respiratory failure in patients with Covid-19, the researchers found. One of these spots includes the gene that determines blood types.
