Not only is that a trend doctors have observed since the beginning of the pandemic, it’s also the finding of a recent study that pooled data from over 3 million people from 47 countries. The paper, published in December in the journal Nature Communications, found that males were 2.84 times more likely to be admitted to the intensive care unit and 1.39 times more likely to die from Covid-19 than females. Notably, males and females had similar rates of infection with SARS-CoV-2, so the differences didn’t stem from men’s greater exposure to the virus but more serious outcomes once they were infected.
