The U.S. Department of State issued a Global Level 4 Health Advisory that requires U.S. residents traveling abroad to immediately return unless they are “prepared to remain abroad for an indefinite period.” Borders between the U.S. and Canada to the north and Mexico to the south are being closed to all but essential travel, which does allow for essential commerce and trade. 

Acting Homeland Security Secretary Chad Wolf said:

“Tonight, at midnight, we will execute the CDC order by immediately returning individuals arriving without documentation to Canada, Mexico, as well as a number of other countries, without delay.”

Officials announced Friday the death of a coronavirus patient in their 70s. The unnamed victim died in a hospital Thursday and is said to have had a pre-existing condition that put them at a higher risk of health complications due to the virus.

Three John Muir Health urgent care centers will be closed so the healthcare provider can concentrate resources in preparation for an influx of patients. The four remaining care centers have separate respiratory treatment areas and all patients admitted will be given a mask. The San Ramon, Orinda and Concord centers will be closed. Centers in Berkeley, Pleasanton, Brentwood and Walnut Creek will remain open. 

The county issued clarified guidance Thursday on farmers’ markets, swap meets and mobile produce trucks, defining them as “essential” services but established restrictions to protect the community from Covid-19 spread.

Merchants selling groceries, prepared foods and household consumer products are permitted to sell, but food preparation booths have been eliminated. Social distancing will be required of all merchants and patrons. Vendors are expected to thoroughly evaluate their own health and not if they are feeling ill or live with anyone who has exhibited acute respiratory illness symptoms.

Mayor London Breed said Thursday that the Emergency Operations Center, which is normally housed at the Department of Emergency Management at 1011 Turk St., has been moved to Moscone Center South.

Mary Ellen Carroll, executive director of the DEM, said the move decided on to ensure city employees have enough space to practice social distancing.

Carroll added that The City’s Emergency Operations Center has been working at the highest level possible since the center was activated back in late February.

The Department of Public Health’s Director Dr. Grant Colfax said his department has already hired 70 nurses since Breed announced the fast tracking hiring policy related to healthcare professionals.

Department of Human Services Agency Executive Director Trent Rhorer said his department has been seeking hotels rooms for The City’s vulnerable residents who cannot shelter-in-place, including homeless individuals living shelters or on the streets and those living in single-occupancy rooms.

Rhorer said officials moved the first few homeless individuals into vacant hotel rooms with a recently secured lease. The individuals were tested at the hospital, but did not require further hospital care. He did not say if they had tested positive for the virus.

Rohorer added that his department has identified 500 hotel rooms so far and the Hotel Council of San Francisco have expressed interest in providing as many as 2,000 rooms at various hotels.

The San Francisco Municipal Transportation Agency said they will begin temporarily adjust parking meter rates citywide. By March 24, all parking meters will be rated at $0.50 per hour for vehicles and $0.10 per hour for motorcycles.
