When do I need to wear a face covering or practice social distancing when working at or visiting a Stanford location?

Effective August 2 at midnight, all Stanford employees, students and visitors – regardless of COVID-19 vaccination status – will be required to wear face coverings while indoors on campus.

This decision is based on guidance from the Santa Clara and San Mateo counties’ August 2 public health orders, requiring face coverings indoors for all individuals regardless of COVID-19 vaccination status. While vaccination is the most effective step we can take to minimize the spread of COVID-19 and the highly transmissible Delta variant, masking provides an extra level of protection and helps keep our community safe.

As per federal and state agencies, physical distancing is no longer required in most circumstances. Please see Health Alerts for more information.
