More Cases in Sonoma County as Testing Slowly Increases

Two more Sonoma County residents have contracted coronavirus, bringing the total known number of local cases to eight, as the scope of a strict Bay Area-wide shutdown expanded to cover Napa, Lake and Mendocino counties.

Mendocino County officials Wednesday confirmed the first case of COVID-19 had been detected there, triggering the public health officer to order residents to stay home and all but essential businesses to cease operations starting at 10 p.m. and lasting through April 7.

Similar community isolation orders go into effect in Lake County at 12:01 a.m. Thursday and 12:01 a.m. Friday in Napa County, directives made by public health officers in those counties, although officials said no local cases of the virus have been confirmed yet.

Public life and commerce came to a near halt for about a half a million residents of Sonoma County who woke up Wednesday to the new directive that left city centers and town plazas all but deserted. By the end of the week, nearly 800,000 residents in four North Coast counties will be under orders to stay home because of unprecedented public health policies designed to slow the spread of the coronavirus and avoid overwhelming hospitals.

As testing for coronavirus ramped up this week at Sonoma County hospitals and health centers, with some offering drive-up service, concerns emerged that limits on the supply of test kits are curbing the process infectious disease experts say is essential to capping the pandemic.

The tests, which amount to a quick throat and nose swab sent to a laboratory for analysis, are only available to registered patients of the health care organizations and authorized by a clinician.

Santa Rosa Community Health, which operates eight clinics around the city, has conducted 25 tests for the new coronavirus since it began drive-up testing last week.

Naomi Fuchs, the chief executive officer, said the organization’s supply of test kits has so far met the demand from patients “with the highest risk and clear symptoms” of a viral infection.

But, she said, “there is a shortage of tests (kits) throughout the county.”

Dr. Sundari Mase, the county’s top public health official, said Wednesday that a shortage of swabs has slowed testing and her team is working to get more shipments of them. She contended, though, there is no shortage of test kits.

So far, 196 coronavirus tests locally have been conducted by county, state and federal laboratories, said Mase, the county’s interim public health officer. That number includes 159 tests done since last Thursday as part of the county’s surveillance project at up to five local health centers to detect whether the virus was spreading within the community. Indeed, the first case of a county resident infected by an unknown source of local transmission was announced Saturday. This week five more local cases were confirmed, including two new ones Wednesday, bringing the total number of county residents diagnosed with coronavirus to six.

Local health care providers are largely hewing to the testing criteria set by the Centers for Disease Control and Prevention: fever, cough and shortness of breath, and adding a history of travel to coronavirus crisis areas around the world such as China — where the virus originated in January — Italy and Spain.

Dr. George Rutherford, professor of epidemiology at UC San Francisco, said high priority also should be given to residents of long-term care centers in the wake of a deadly outbreak at a Seattle area nursing home this month.

Health care workers warrant testing to avoid sidelining them for a 14-day quarantine, and tests also should be available to homeless people due to the threat of spreading the virus around the community, he said.

South Korea stabilized one of the world’s worst coronavirus outbreaks by testing more than 200,000 people, Rutherford said.

Although the pace of testing activity is picking up daily, still only a fraction of the county’s population of about 500,000 has been tested.

Kaiser Permanente started a drive-through coronavirus testing program in Santa Rosa allowing patients who have a doctor’s order to roll up and be swabbed by a health care worker in protective garb without leaving their cars.

Kaiser, which has multiple health centers in Santa Rosa, also has set up “other alternative sites” for coronavirus testing, said Michelle Gaskill-Hames, the senior vice president for hospital operations for Kaiser Permanente Northern California.

She declined to name the locations out of concern crowds could come and interfere with private clinical appointments.
