The new coronavirus has reached Oregon, and the situation is changing fast. Here’s what we know as of March 1.

The lone case: Oregon’s first and so far only coronavirus patient worked at Forest Hills Elementary School in Lake Oswego but did not have a job with close student contact. School and health officials still have not identified the person or said anything about the person’s condition.

Who else: The Lake Oswego superintendent said a limited number of people had contact with the person. She did not identify who they were, their relationship to the patient or how many. Their last possible close contact with the person was Feb. 19. An Oregon person who was under investigation as a possible case of COVID-19 has tested negative for the disease. Seven other people who are showing symptoms of the disease and may have been exposed have undergone testing but the results aren’t known yet, officials said.

More results expected: The Oregon Health Authority plans to release new test results Sunday for people potentially exposed to coronavirus. The state lab is collecting samples between 10 a.m. and noon, with results expected to be publicly released in the afternoon.

CORONAVIRUS IN OREGON: FULL COVERAGE

Deep clean: A team from contractor ServPro was onsite and evaluating Forest Hills Elementary on Saturday for a deep clean and could start as early this weekend, district officials said.

Other schools: The Lake Oswego School District has no plans to close other schools. Forest Hills is closed through Wednesday.

A negative test: A second person who was under investigation for the illness, unrelated to the Forest Hills employee, tested negative on Saturday, officials said. At least seven other tests are pending and 88 people are being monitored for the disease, according to the Oregon Health Authority.

Portland Public Schools: The district sent an email to families late Saturday saying they “continue to monitor the situation in Lake Oswego, and we are in continual contact with government agencies and our public health partners, including Oregon Health Authority, Multnomah County, and the Oregon Department of Education.”

They asked students, families and staff to “support our proactive efforts by washing hands frequently, covering mouths when coughing or sneezing, and using hand sanitizer,” and said anyone experiencing cold or flu symptoms should follow guidelines and stay home.

Transmission risk: Health experts repeated that coronavirus is most dangerous for old people and those with underlying conditions. The vast majority of cases are mild. The virus is thought to be spread from person to person when in close contact – within about 6 feet – through droplets emitted when a person coughs or sneezes. It may also be possible to catch the virus by touching a surface that has the virus and then touching the mouth, nose or eyes.

Best advice: Stay home if sick, call your doctor if you have trouble breathing or other significant symptoms and determine if you need to seek further treatment or can stay home. Kids in the metro area with any symptoms should stay home. Do not go to a doctor if your only reason for going is fear of a coronavirus infection.

What’s next: The Oregon Health Authority says it will let people know almost immediately after it learns of any new cases. They announced Saturday that a person under investigation unrelated to the Forest Hills employee tested negative.The state is now able to do its own tests for coronavirus, meaning that officials don’t have to wait days for the CDC to tell them if someone is sick.

Coronavirus quarantine kit: Don’t panic, but do stock up. Here’s a quick list of supplies to have in your home in case of a broader outbreak or quarantine, and links to buy each one.

How to prevent coronavirus: The advice is pretty simple, and it’s easy for most people to follow. First up: Know the symptoms.

More Washington cases: Washington health officials confirmed Sunday that there were two more confirmed cases of coronavirus in the Seattle area. That brings the total confirmed cases in Seattle to six and in Washington state to eight. Also Sunday, researchers said it was possible that coronavirus had been circulating undetected in Washington for as many as six weeks.

Trump and the ‘hoax’: The coronavirus outbreak’s impact on the world economy grew more alarming on Saturday, even after President Donald Trump denounced criticism of his response to the threat as a “hoax” cooked up by his political enemies.

Remembering the flu: With Americans increasingly nervous about what to expect from the novel coronavirus pandemic, public-health experts and historians have pointed to the worldwide 1918-19 Spanish flu outbreak as an example of what not to do.
