A型血更易感新冠病毒?

People with Type A blood are significantly more likely to catch coronavirus than those with Type O, Chinese academics have found.
中国学者发现，A型血的人感染上新冠肺炎病毒的风险比O型血的人大得多。

The study in Wuhan also found those with Type A blood are more likely to die from COVID-19.

In the general population Type O blood (34%) is more common than A (32%).

However, among COVID-19 patients, people with Type O accounted for just 25%, whereas Type A made up 41%.

People with Type O blood made up a quarter (25%) of deaths in the research.
