A major study in India offers insights into on how the spread of the virus differs by age and gender.
An ambitious new study of nearly 85,000 coronavirus cases in India and nearly 600,000 of their contacts, published Wednesday in the journal Science, offers important insights not just for India, but for other low- and middle-income countries.
India now has more than six million cases, second only to the United States.
Among the findings of the study: The median hospital stay before death from Covid-19, the illness caused by the coronavirus, was five days in India, compared with two weeks in the United States, possibly because of limited access to quality care. And the trend in increasing deaths with age seemed to drop off after age 65 — perhaps because Indians who live past that age tend to be relatively wealthy and have access to good health care.
The contact tracing study also found that children of all ages can become infected with the coronavirus and spread it to others
