Children can spread coronavirus among themselves efficiently, but young adults are the primary source of coronavirus spread, according to a study published Wednesday.
The study, based on a giant contact tracing effort involving more than 3 million people in India, shows most COVID-19 patients never infected anyone else. The researchers found that 70 per cent of infected people did not infect any of their contacts, while 8 per cent of patients accounted for 60 per cent of observed new infections.
The study also contradicts the widely held belief that children are unlikely to catch the coronavirus.

"While the role of children in transmission has been debated, we identify high prevalence of infection among children who were contacts of cases around their own age," the team wrote in their report, published in the journal Science.
