Blood group O associated with a decreased risk of Covid infection

Blood group O associated with a decreased risk of Covid infection

Meanwhile, blood type B is much less common with just 8 per cent of the population having it. However, people who have blood types A and AB are the most vulnerable to the infection. Earlier in March, a study of over 2,100 coronavirus patients in Wuhan and Shenzhen (also not peer-reviewed) found that people with Type O blood had a lower risk of infection.

A growing body of evidence suggests those who have blood type O may be less likely to contract coronavirus and typically experience less severe symptoms when they do come down with the illness.

They wrote that patients with blood groups A or AB were more likely to require mechanical ventilation (34, or 84%) versus those with blood group O or B (35, or 61%), which means that their risk of lung injury from Covid-19 was greater.

They are also at lower risk of severe Covid-19 outcomes, such as organ failure, and even death. Researchers in Denmark find fewer coronavirus patients have O blood compared to those with A, B, and AB blood. Further investigations on the mechanism of the different susceptibility to COVID-19 between blood group A and O individuals are needed and regardless of your blood type, you need to follow public health recommendations. Both studies were published in the journal Blood Advances this week. 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.

In July, a study looking at 1,600 patients in Spain and Italy showed slightly higher rates of severe respiratory failure in patients with blood type A compared to those with blood type O.

Police finally identify man who killed nine-year-old Christine Jessop
The work to finally track down Jessop's killer involved "excellent police work", said CTV News Public Safety Analyst Chris Lewis. However, he was only identified as a potential suspect through genetic genealogy tracing done in the United States.

Anyone with blood type O negative are universal donors as in they can donate their blood to all groups. Individuals with O blood have neither antigen. "I don't think this overrides other danger components of seriousness like age and comorbidities and so forward", he told CNN, including, "on the off chance that one is blood bunch A, you don't have to begin freezing".

"It is very important to consider the proper control group because blood type prevalence may vary considerably in different ethnic groups and different countries", says study author Torben Barington, MD, of Odense University Hospital in a press release.

Health officials have estimated that 60,000 people could be suffering with long-term after effects of COVID-19.

Regardless of this developing group of proof, be that as it may, Mypinder Sekhon, a co-creator of the Vancouver study, said the link is as yet questionable.
