Bay Area public health officials on Sunday reported new coronavirus cases, bringing the total to 37 in Santa Clara County and nine in Contra Costa County.

Five new cases were reported Sunday in each county. County health officials did not provide additional information about the new cases. There were no announced fatalities as of Sunday in either the Santa Clara County or Contra Costa County cases.

In addition to the nine confirmed cases in Contra Costa County, three people were transferred to Contra Costa County from an out-of-county location to receive care. At least two of the nine of the Contra Costa residents who have contracted the virus were on the same Grand Princess cruise ship that was attended by a Northern California man who later died from the virus.

“As we ramp up our testing, we expect to identify more cases. But there is still a lot we can do to slow down the spread and protect our most vulnerable,” Dr. Ori Tzvieli, acting Contra Costa Health Officer, said in a press release Sunday.

County public health officials have called for employers and event organizers to cancel any large gatherings, such as concerts, sports games and conferences, in order to limit the spread of the virus. Many organizations have done so.

They have also urged employers to suspend non-essential employee travel, minimize employees working within arm’s length of one another and allow employees to work from home whenever possible.

These measures were added on top of a warning earlier this week by county public health officials for those over the age of 50 or with poor health conditions to avoid large public gatherings.

In accordance with the recommendations from Santa Clara County public health officials, for instance, San Jose Diocese Bishop Oscar Cantu granted those at a greater risk of contracting the virus a special dispensation to stay home from mass for the time being.

“In light of the delicate situation we are facing at this time, I dispense persons falling into the categories of greater risk from attending Mass,” Cantu said in a statement. “May we continue to observe the precautions prescribed by our public health department to protect ourselves and our brothers and sisters.”

Over the weekend, Oak Grove High School in San Jose was undergoing a “deep cleaning” after one student was confirmed to have had contact with a family member who has contracted the virus, school officials said.

Though the student had not exhibited any symptoms, they were being quarantined and will be tested for the virus, the school said in a press release. Classes have not been canceled and will go on as planned on Monday.

Meanwhile, in San Francisco, at least two schools will be closed on Monday over concerns about the virus.

Lowell High School, which was one of the first schools to close in the Bay Area last week, will not resume classes on Monday. School officials closed the school Thursday afternoon because a parent of a student at the school had tested positive for the virus.

Immaculate Conception Academy Cristo Rey, a Dominican Catholic college preparatory school in San Francisco, announced Sunday that it would be close for two weeks because a custodial staff member tested positive for the virus. The school has hired a company to deep clean all of the school buildings, and it plans to resume classes on Friday, March 20, Principal George Fornero said in a letter to parents and students.
