Researchers at Harvard’s GenderSci Lab investigated the intersectionality of race, sex, and Covid-19 mortalities, as detailed in a study published earlier this month in the Journal of General Internal Medicine. Previous studies have found the mortality rate of Covid-19 is higher in men than in women, and higher in Black individuals than in white individuals. However, unlike previous studies, this new paper — a collaboration across Harvard, MIT, University of Adelaide, and University of Southern Maine — found that the sex disparity greatly varies by race.
