Coronavirus: Another Case Reported In Napa County; Total Of 2

NAPA COUNTY, CA — Napa County reported a second case of the new coronavirus hours after it reported its first.

The newly confirmed case involves a St. Helena patient who is in isolation, Napa County Public Health said Sunday evening in a news release. There is no known connection to the first case, a patient in Napa.

County officials say they are investigating and working to identify close contacts of the patient.

County Public Health Officer Karen Relucio said it is critical that people experiencing respiratory symptoms stay home even if they feel alright.

"As a community, we need to act now to slow the spread of the virus," she said.

Ninety-two patients have been tested for coronavirus as of Sunday morning and 30 are waiting for results, said county spokesperson Noel Brinkerhoff.

Bay Area counties expect more positive results as more people are tested.

California remains under a stay-at-home order, meaning everyone must stay inside unless they must get critical supplies, receive critical services or perform critical work.

On Sunday President Donald J. Trump said he would approve Gov. Gavin Newsom's request to declare a major disaster in California, freeing up federal resources to fight the state's growing coronavirus outbreak.

Trump also said he would send the USNS Mercy, a massive Navy hospital ship, to Los Angeles to help treat the area's surge of coronavirus patients. Previously, officials in Seattle had expected the ship would head there.

Newsom previously declared a state of emergency to provide additional resources, prevent price gouging and help the state better prepare for the virus's spread.

The emergency declaration followed the first known coronavirus-related death in California — an elderly Placer County resident who was exposed to the virus on a Grand Princess cruise Feb. 11-21 from San Francisco to Mexico and back.

Coronaviruses are a family of viruses that include the common cold as well as much more serious diseases. The strain that emerged in China in late 2019, now called COVID-19, is related to others that have caused serious outbreaks in recent years, including severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

The first confirmed case of COVID-19 in the U.S. was on Jan. 21.

The disease, which apparently originated in animals, is now transferring from person to person, although the mechanism is not yet fully understood. Its symptoms include fever, coughing and shortness of breath, and many patients develop pneumonia.

There is as yet no vaccine against COVID-19 it and no antiviral treatment.

According to the CDC, the best way of preventing the disease is to avoid close contact with others, maintain six feet of distance between others, to avoid touching your eyes, nose, and mouth with unwashed hands, to wash your hands often with soap and water for at least 20 seconds, and to use a hand sanitizer that contains at least 60 percent alcohol if soap and water are not available.

To avoid spreading any respiratory illness, the CDC recommends staying at home when you are sick, covering your cough or sneeze with a tissue and throwing the tissue in the trash, cleaning and disinfecting frequently touched objects and surfaces.
