SAN JOSE — Health officials have confirmed the second case of novel coronavirus in the United States believed to have been transmitted to a person who didn’t travel internationally or come in close contact with anyone who had it.
The U.S. Centers for Disease Control and Prevention said Friday that officials are “aware of a second possible instance of community spread of COVID-19 in California." The CDC said in a statement that the patient has tested positive for the virus and is considered a presumptive positive case.
Health officials in San Jose said the patient was an older adult woman with chronic health conditions who does not have a travel history or any known contact with a traveler or infected person. It comes a day after state officials said a woman hospitalized at UC Davis Health Center in Sacramento had contracted the illness after no known contact.
“This new case indicates that there is evidence of community transmission but the extent is still not clear,” said Dr. Sara Cody, Health Officer for Santa Clara County and Director of the County of Santa Clara Public Health Department.
Solano County Public Health Officer Dr. Bela Matyas said public health officials have identified dozens of people — but less than 100 — who had close contact with the woman. They are quarantined in their homes. and a few who have shown symptoms are in isolation, Matyas said.
Health officials on Friday confirmed another case of the novel coronavirus in Northern California, raising the tally a day after health officials revealed the first case in the U.S. believed to have been transmitted to a person who didn't travel internationally or come in close contact with anyone who had it.
Santa Clara County Public Health Department spokesman Maury Kendall said the person is isolated at home and that other details would be provided later Friday.
A day earlier, state health officials had pegged the number of people in California with the virus at 33 after investigators announced that a woman hospitalized in Sacramento contracted it.
Residents of the community where the woman first went to the hospital, in Vacaville, are at the epicenter of what officials are calling a turning point in the spread of the highly contagious coronavirus,
As infectious disease experts fanned out in Vacaville, some residents in the city of 100,000 stocked up on supplies amid fears things could get worse despite official reassurances, while others took the news in stride.
Vacaville lies between San Francisco and Sacramento in Solano County, in the agricultural central valley and near California’s famous wine region.
It is about 10 miles (16 kilometers) from Travis Air Force Base, which has been used as a virus quarantine location. Public health officials said they can find no connection between the infected woman and passengers on the Diamond Princess cruise ship who were evacuated to the base when the ship was docked in Japan.
The case of the infected woman marks an escalation of the worldwide outbreak in the U.S. because it means the virus could spread beyond the reach of preventative measures like quarantines, though state health officials said that was inevitable and that the risk of widespread transmission remains low.
California public health officials on Friday said 8,700 people are self-monitoring after arriving on commercial flights from China through Los Angeles and San Francisco. That's up from the 8,400 that Gov. Gavin Newsom cited on Thursday, though officials said the number increases daily as more flights arrive.
Solano County Public Health Officer Dr. Bela Matyas said public health officials have identified dozens of people — but less than 100 — who had close contact with the woman there. They are quarantined in their homes and a few who have shown symptoms are in isolation, Matyas said.
Officials are not too worried, for now, about casual contact, because federal officials think the coronavirus is spread only through “close contact, being within six feet of somebody for what they’re calling a prolonged period of time,” said Dr. James Watt, interim state epidemiologist at the California Department of Public Health.
The virus can cause fever, coughing, wheezing and pneumonia. Health officials think it spreads mainly from droplets when an infected person coughs or sneezes, similar to how the flu spreads.
“I’m definitely going to wear my mask and gloves at work, because I’m a server,” said Vacaville bowling alley worker Denise Arriaga, who said she doesn’t care if she’s criticized for the extra precautions.
“At the end of the day, it’s my life,” she said.
The woman first sought treatment at NorthBay VacaValley Hospital in Vacaville, before her condition worsened and she was transferred to the medical center.
Confusion over how quickly the woman was tested for coronavirus concerned McKinsey Paz, who works at a private security firm in Vacaville. The company has already stockpiled 450 face masks and is scrambling for more “since they’re hard to come by.” The company's owner bought enough cleaning and disinfectant supplies to both scrub down the office and send home with employees.
But they appeared to be at the extreme for preparations.
Eugenia Kendall was wearing a face mask, but in fear of anything including the common cold. Her immune system is impaired because she is undergoing chemotherapy, and she has long been taking such precautions.
“We’re not paranoid. We’re just trying to be practical,” said her husband of 31 years, Ivan Kendall. “We wipe the shopping carts if they have them, and when I get back in the car I wipe my hands — and just hope for the best.”
In their investigation of the movements of the hospitalized woman, officials were trying to figure out how she got it and who else she may have unwittingly infected.
They are interviewing immediate family members and expanding their net to include more distant family members who may have been in contact, social gatherings like church that the patient may have attended and any possible time spent at work or events like a concert.
Besides the woman, all the 59 other cases in the U.S. have been for people who traveled abroad or had close contact with others who traveled.
Earlier U.S. cases included 14 in people who returned from outbreak areas in China, or their spouses; three people who were evacuated from the central China city of Wuhan; and 42 American passengers on the Diamond Princess cruise ship.
The global count of those sickened by the virus hovered Friday around 83,000 and caused more than 2,800 deaths, most of them in China.
