FILE - In this Wednesday, Aug. 12, 2020 file photo, parents wait with children on the schoolyard for the start of their first day at a school in Gelsenkirchen, Germany. Just in time for back-to-school for millions of kids, the World Health Organization on Monday, Aug. 24, 2020 has issued guidance about mask-wearing by children, suggesting in particular that those aged 6 to 11 should wear them too in some cases to help fight the spread of the coronavirus. The WHO recommendations follow upon the widespread belief that children aged under 12 are not considered as likely to propagate the virus as much as adults.
