A few reports on the blood types most affected by the Coronavirus.
Most of COVID patients have blood type A, says Russian health official
MOSCOW, May 15, 2020 - Most of coronavirus patients have blood type A, while those having blood type AB are the fewest,
chief of Russia’s Federal Medical Biological Agency Veronika Skvortsova said on Friday.
"An interesting fact that was noted by foreign specialists and has been verified by the Agency’s centers.
The overwhelming majority of those infected have blood type A," she said at an online news conference organized by TASS.
Next are types O and B. And, indeed, the rarest is type AB."
She noted however that it might be because type A is the most widespread among the population.
Does Your Blood Type Increase Your Risk for Coronavirus?
A recent study from China concluded that people with type A blood may have a higher risk of contracting the new coronavirus than people with type O do.
The
recent study came out of Wuhan, China, where the first known cases of COVID-19 were discovered. It’s published on a website, but hasn’t yet been reviewed by peers.
In the study, scientists looked at the blood types of 2,173 people who had been diagnosed with COVID-19 and compared that with the blood types of the general population in that region.
They found that in the normal population, type A was 31 percent, type B was 24 percent, type AB was 9 percent, and type O was 34 percent. In those with the virus, type A was 38 percent, type B was 26 percent, type AB was 10 percent, and type O was 25 percent.
The researchers concluded that “blood group A had a significantly higher risk for COVID-19 compared with non-A blood groups. Whereas blood group O had a significantly lower risk for the infectious disease compared with non-A blood groups.”
Dr. Foster has looked at the
connection between intestinal illnesses such as
norovirus and blood types.
“Norovirus has a clear biological reason why blood type would make a difference,” she said. “The norovirus actually uses the sugars on the cell surface to attach itself to the cell.”
In general, people who don’t make the H1-antigen and those with B type blood will tend to be resistant, whereas people with A, AB, or O blood types will tend to get sick.
Does Blood Type Affect Coronavirus Risk? - MedicineNet Health News
FRIDAY, March 20, 2020 -- A person's
blood type may affect their risk for
COVID-19, the disease caused by the new coronavirus, researchers report.
They analyzed blood samples from nearly 2,200
COVID-19 patients in China and tens of thousands of healthy people, and found those with A
blood types had a significantly higher risk of
COVID-19 while those with O
blood types had a significantly lower risk,
Newsweek reported.
The findings appear on the website
medRxiv, where health researchers publish studies before they undergo the peer review process required by journals.
The researchers said
blood type-related differences in
COVID-19 risk may be due to certain antibodies in the blood, but further studies are needed to confirm this,
Newsweek reported.
The finding that blood type may affect
COVID-19 risk could be important for healthcare workers treating
COVID-19 patients, because those with A blood types" "might need particularly strengthened personal protection to reduce the chance of infection."
Also, people with A blood types might require "more vigilant surveillance and aggressive treatment," and identifying a person's blood type as a routine part of treating COVID-19 and other coronavirus infections might be helpful, according to the researchers,
Newsweek reported.
The study was limited because of its small size and it didn't offer an explanation for its findings, Gao Yingdai, a researcher from the State Key Laboratory of Experimental Hematology in Tianjin, told the
South China Morning Post.
