March 17, 4:32 p.m., San Francisco Mayor London Breed has issued a moratorium on evictions for the city's small and medium-sized businesses. According to a press release on the mayor's website, this ban applies to businesses with less than $25 million in annual gross profits.

"We are taking action to make sure that our small businesses are not displaced as a result of the economic impact caused by coronavirus," she stated. "We will continue to push for more immediate state and federal support in addition to the programs we’ve introduced locally, because this pandemic is having major widespread economic impacts on almost every business and resident in our city.”

Part of the effort includes deferring small business taxes and licensing fees, and the launching of Give2SF.org, which gathers donations to be distributed to local small businesses and workers impacted by coronavirus.

March 17, 3:17 p.m., Sonoma County is expected to follow suit with six other Bay Area counties in ordering a shelter in place as soon as Tuesday night at midnight, the Press Democrat reported Tuesday afternoon. The county's interim public health officer, Dr. Sundari Mase is reportedly hoping to issue the official order "as soon as possible."

Sonoma County has six confirmed cases of COVID-19 thus far — far fewer than most other local counties — and health officials hope that going through with the order will help curb new ones.

"If we put [the order] in place now, we are way ahead of the game," Dr. Mase told the Press Democrat. "We could prevent cases. I think it’s something we need to consider."

Dr. Mase, who was placed in the interim public health officer position just a week ago, will further clarify her remarks in an online town hall meeting on Tuesday at 7 p.m.

Separately, the County tweeted they would be scaling back and offering only essential services to residents beginning Wednesday.

March 17, 7:14 a.m. UCSF emergency room doctor Rosny Daniel tested positive for COVID-19 on Saturday and has shared his story on Medium.

He wrote that he initially felt "slightly sick" with a mild cough on Thursday evening. On Friday, he still had that pre-sick feeling with muscle soreness and an elevated temperature.

"I didn’t know if I was really going to get sick or not, but I didn’t want to risk getting others sick so I asked around and was able to get out of my shift," Daniel wrote. "I contacted my leadership team and was instructed to go get tested."

On Saturday morning, he learned he had tested positive. "Physically, I feel fine," he wrote. "Mild muscle soreness and headaches mostly. I haven’t had any more fevers since waking up a little sweaty Friday morning. My breathing is fine. No nausea, vomiting, diarrhea."

Daniel said he's anxious because he's type 1 diabetic, as well as asthmatic, and he knows "this disease can get a lot worse very fast."
