SAN FRANSISCO, Calif. — Kids are learning to do coronavirus testing on themselves, which could cut PPE costs for schools.

It's part of an ongoing study at two San Francisco summer camps. The tests are a little different. They use the same swab but instead of pushing deep into the nose kids are just asked to wipe around the inside of the nostril.

Researchers say kids doing their own swabs allows for more physical distancing and therefore less need of PPE. Another school-based study is being planned for the fall.
