"We're extending the health officer orders -- which, as you know, require a fair amount of distancing and continue to keep in place closures of non-essential business -- not because everything everyone has been doing isn't working...it's because it is working. We know it's effective, but we still have a ways to go in order to both protect the lives of people who live in our county and to make sure that our health care system remains fully able to service all who need their care," said Dr. Barbara Ferrer, director of the Department of Public Health.
The new health order requires each essential business to implement and document a social distancing and sanitation plan, and requires the plan to be visibly posted at the front of individual business locations.
