LATEST, March 10, 8:30 p.m. Three Transportation Security Officers at Mineta San Jose International Airport tested positive for COVID-19, TSA officials said.

The infected employees are receiving medical care, and all TSA employees they had contact with over the past 14 days are quarantined at home.

"Screening checkpoints remain open and the agency is working with the CDC, as well as the California Department of Public Health and the Santa Clara County Public Health Department to monitor the situation as well as the health and safety of our employees and the traveling public. We will update as more information becomes available," TSA said in a statement.

It's unclear if these cases are among the 45 cases already reported by public health officers in Santa Clara County.

Elsewhere, Contra Costa County announced one presumptive case of COVID-19 on Tuesday afternoon, bringing the county total to 10 residents. The county has also treated non-residents in hospitals. County officials have called for cancellations of public events with 50 or more people.

A new case was also detected in Alameda County, the county's third. The county is calling for the cancellation of events with 1,000 or more people.

March 10, 3:15 p.m.: The Archdiocese of San Francisco announced all 90 of its Catholic schools in San Francisco, San Mateo and Marin counties would close for two weeks after a student tested positive for COVID-19. Buildings will be closed, classes and activities canceled, and all learning material will be distributed "utilizing the Archdiocesan distance learning protocol," the superintendent said in a statement. The closures affect 22 preschools, 55 elementary schools and 13 high schools across the three counties. Read the latest on school closures around the Bay Area here.

March 10, 2:52 p.m.: Another two cases of COVID-19 were confirmed in Santa Clara County, bringing the county's total to 45.

"We expect numbers to grow & urge everyone to follow Public Health recommendations," the Public Health Department said on Twitter.

The county didn't immediately release details on the two new individuals. Of the 43 prior-known cases, 21 are hospitalized (10 are in intensive care). Eight were exposed through international travel, 14 through contact with another known coronavirus patient, and 21 through community transmission.

March 10, 2:35 p.m.: A San Francisco Wells Fargo employee is one of those who tested positive for the novel coronavirus in the city, according to KGO.

The employee reportedly worked in an office at 555 California St., one of the city's largest skyscrapers. Other tenants at 555 California include Bank of America, Goldman Sachs and Microsoft.

March 10, 2 p.m.: In a news briefing, Gov. Gavin Newsom said 157 people have tested positive for COVID-19 statewide. So far, 7,675 tests are available at 18 labs around the state. Newsom said the state is working to rapidly scale up testing capabilities.

"Many of these test kits are like printers but without ink," Newsom explained, saying key components are missing in order to make tests more widely available. He said he was pressuring the CDC to help make re-agents, the aforementioned missing component, more widely available.

Newsom praised Santa Clara County officials for shutting down large events, but said there weren't yet any plans for similar measures statewide.

"The conditions are distinctive in Santa Clara ... the number of cases in Santa Clara distinguish it," Newsom said, before addressing how professional sports teams are addressing the epidemic. "I found it quite curious that the four major organizations — NHL, soccer, Major League Baseball and the NBA — put out guidelines to protect their players but not their fans."

He also spoke about quarantine protocol for the 3,500 people onboard the Grand Princess cruise ship docked in Oakland. Newsom said those who need critical care are being tended to first, before Californians and then finally non-Californians. So far, passengers have been moved to Travis Air Force Base in Fairfield. Evacuees will also be taken to Marine Corps Air Station Miramar in San Diego. Crew will be quarantined on the ship.

March 10, 12:35 p.m.: BART ridership has suffered a dramatic drop since coronavirus began to spread in the Bay Area.

Ridership was down 25% on Monday, March 10 as compared to Monday, Feb. 24, BART spokesperson Alicia Trost told KQED reporter Dan Brekke.

There were 301,547 riders Monday compared to 403,002 on Feb. 24, Brekke reports.

The drop in ridership came as many Bay Area companies instructed employees to work remotely to avoid potential COVID-19 contamination or spread.

Contra Costa County also declared a state of emergency Tuesday afternoon, a move that will make it easier to get state and federal resources to fighting the spread of the virus.

March 10, 10:30 a.m.: San Francisco public health officials reported another case of COVID-19 Tuesday, bringing the city total to 14.

The new case is a patient who had known contact with an infected person; the individual is hospitalized.

This news comes after the city announced five new cases on Monday.

In Santa Clara County, supervisors unanimously voted Tuesday to extend the local health emergency declaration banning all gatherings of over 1,000 people through April 9, NBC News reported.

Santa Clara County reported six new cases Monday and now has 43 infected patients, the highest number of known cases in any Bay Area county. To prevent spread, city officials are banning gatherings and asking the public to maintain social distancing. The ban does not apply to airports, shopping malls, grocery stores or offices, and is enforceable by both the sheriff's office and local police departments. It goes into effect on Wednesday.

"This is all hands on deck," Santa Clara County health officer Dr. Sara Cody said in a press conference Tuesday. "We each have a role to play."

On Monday, Marin County announced its first case and San Mateo public health officials announced the county now has nine cases.

The patient was under treatment in isolation at Kaiser Permanente Roseville.

The second California death, the first in the Bay Area, was reported in Santa Clara County in March 9.

Health officials said the patient had an underlying health condition and "died of complications" related to the pneumonia-like virus.

The death of a 72-year-old man from Sunnyvale was previously thought to be linked to COVID-19, but test results confirmed the man did not have the virus.
