Exposure to COVID-19 explains racial disparities in mortality rates: study

CHICAGO, Dec. 10 (Xinhua) -- Large variations in exposure at home, in the community and at work rather than case-fatality rates may explain the well-documented racial disparities in COVID-19 mortality during the first wave of the pandemic last spring, according to a University of Michigan (UM) study.

Using the Michigan Disease Surveillance System from March to July 2020, the researchers analyzed data from 49,701 people with a confirmed or probable COVID-19 infection, with known age, race or ethnicity, state of residence, sex at birth and state prisoner status.
