People with type A blood may be more defenseless against Covid-19 than those with type O, who may be more resistant, according to a Chinese scientific study.
The research was carried out by the Wuhan Center for Evidence-Based Medicine and Translational Medicine, considered the epicenter of the pandemic and disclosed on the online portal Medrxiv.org.
The research compared the blood types of 2,173 confirmed coronavirus cases at three hospitals in Wuhan and Shenzhen with more than 3,694 healthy residents of the same area and found that the number of Type O patients infected with the virus was lower.
"People in blood group A may need specially strengthened personal protection to reduce the chance of infection," said researchers whose team was led by expert Wang Xinghuan, the New York P os t reported.
The study also examined 206 patients who died from the virus, finding that 41.26 percent had type A blood while only a quarter had type O.
According to the Post, researcher Gao Yingdai explained that this does not mean that types A should panic or that types O are safe.
More than 200,000 patients have been infected by the virus worldwide, of which more than 8,000 have lost their lives, according to the World Health Organization (WHO).
