Coronavirus Watch: More cities require proof of vaccination for indoor activities

Starting Tuesday, people ages 12 years and older in New York City will be required to show proof of at least partial vaccination to participate in indoor activities such as dining and using gyms.

"If we’re going to stop the delta variant, the time is now," Mayor Bill de Blasio said Monday. Enforcement of the policy begins Sept. 13, according to the mayor's office.

In New Orleans, a vaccination requirement for all indoor venues and outdoor gatherings of more than 500 people went into effect Monday. In San Francisco, a requirement for indoor activities goes into effect Friday.

It's Tuesday, and this is Coronavirus Watch from the USA TODAY Network. Here's more news you need to know.
