In China, only 2.4 percent of reported cases were children and only 0.2 percent of reported cases were children who got critically ill, according to the World Health Organization. China has reported no case of a young child dying of the disease covid-19.

The fatality rate in China for those over 80 is an estimated 21.9 percent, per the WHO. For ages 10 to 39, however, the fatality rate is roughly 0.2 percent, according to a separate study drawing on patient records of 44,672 confirmed cases. And fatalities and severe symptoms are almost nonexistent at even younger ages.
