Infectious disease specialists surveyed by NPR say they're not ditching their masks just yet.

The federal health agency released new guidance for when Americans need to mask up indoors, saying about 70% of the population lives in a place where it's safe to go mask free.

Despite pressure from health experts who advocated for adding a testing requirement, the agency is standing by its original guidance that a negative test is not needed for people who are fever-free and whose symptoms have improved.

Cutting the isolation for positive cases to five days could lead to more infections if people don't take masking seriously. A testing requirement, would have made the policy safer, experts say.

Some public health experts are also parents of little kids, and have to strategize to keep those too young to be vaccinated safe from getting or spreading the delta variant. Here are their tips.
