Researchers estimate children and teens are half as likely to catch COVID-19 as people who are over the age of 20. That's according to a new modeling study published in the journal Nature Medicine.

The research used transmission models to estimate disease susceptibility and the relation of age to cases.

Researchers estimate that clinical symptoms manifest in only around 21-percent of 10 to 19-year-olds. That estimate rises to around 69-percent in people aged 70 and up.

They also said children could experience less severe symptoms of the virus.

As for the asymptomatic transmission, the authors said more research is needed.
