San Francisco Mayor London Breed announced Monday that health officials are extending the city's stay-at-home order through May.
Six counties in Northern California, including San Francisco, plus the city of Berkeley, will introduce extended stay-at-home orders this week, according to a joint statement released by county health officials. The extended orders will also include the lifting of certain restrictions.
"We do expect some lower-risk activities to be allowed to resume soon, but for the safety of you and those around you we must build on the progress we've made," Breed said in a tweet Monday announcing the order's extension.
She said that the city does not want to relax restrictions too early in the event there's a spike in cases and even stricter restrictions on city residents are required.
San Francisco banned gatherings of more than 1,000 people on March 11 and joined five other Bay Area counties on March 16 as the first region in the U.S. to order residents to "shelter in place," that is, avoid leaving their homes except for essential business such as grocery shopping and medical visits. On March 19, the entire state of California followed suit.
Infectious disease experts say that the region's early steps, including ordering people to avoid crowds and shelter in place, may have slowed the trajectory of the virus. But experts say it remains critically important that residents continue to heed the advice of public health officials and stay home.
San Francisco and the other six counties said that hospitalizations "have leveled" in their joint statement, but that prematurely lifting restrictions could lead to a large surge in cases and cause the virus to spread further.
The group also plans to release "a set of broad indicators" that will be used to track their progress in responding to the coronavirus, according to the joint statement. The counties' health officials expect to be responding to the coronavirus for "a long time" in their communities.
Breed also announced Monday that starting Tuesday at 6:00 am, two roads in major parks will be closed to vehicles in order to encourage physical distance. A portion of John F. Kennedy Drive in Golden Gate Park and John F. Shelley
Drive in John McLaren Park will be closed to vehicles 24 hours per day throughout the duration of San Francisco's stay-at-home order, according to a statement from the mayor's office.
"We know that people need to go outside, whether to get exercise or just clear their head, and closing JFK and Shelley Drive to cars will make it easier for people who choose to leave their home to stay six feet apart from others," Breed said.
