Also on Friday, ACPHD said it will comply with the California Dept. of Public Health’s mass gathering guidelines by prohibiting gatherings of over 250 people at the Alameda County Fairgrounds.

All non-essential gatherings of 250 people or more are recommended to be canceled or postponed, both by the county and the state of California. County health officials also emphasize social distancing by leaving at least six feet in between each person in gatherings inside confined spaces.

“Taking these additional preventive measures now will help us reduce the number of people who get sick, and avoid prolonged adverse impacts on our health care system, workforce, and communities,” said county health officer Dr. Erica Pan.
