California Governor Gavin Newsom issued an executive order that required the use of face coverings “in common and public indoor spaces and outdoors when distancing is not possible.”
Newson said in a statement, “Simply put, we are seeing too many people with faces uncovered — putting at risk the real progress we have made in fighting the disease. California’s strategy to restart the economy and get people back to work will only be successful if people act safely and follow health recommendations. That means wearing a face covering, washing your hands and practicing physical distancing.”
There are some exceptions to the order — including for children under 2 years old, and those with legitimate medical cause — but it would seem to cover stadiums when it requires them to be worn “in any room or enclosed area where other people (except for members of the person’s own household or residence) are present when unable to physically distance.”
Besides any legal requirement, wearing a face covering or mask ought to be common practice among any population wanting to stop the spread of COVID-19 based simply on common human decency.
