A person in California who was not exposed to anyone known to be infected with the coronavirus, and had not traveled to countries in which the virus is circulating, has tested positive for the infection. It may be the first case of community spread in the United States, the Centers for Disease Control and Prevention said on Wednesday. “At this point, the patient’s exposure is unknown,” the C.D.C. statement said. “The case was detected through the U.S. public health system and picked up by astute clinicians.” (Rabin, 2/26)

California officials said the person is a resident of Solano County, northeast of San Francisco, and is getting medical care in Sacramento County. They said they have begun the process of tracking down people who the patient has been in contact with, a process known as contact tracing. The patient was brought to UC Davis Medical Center from another Northern California hospital on Feb. 19 but it was four days before the CDC heeded a request to test the patient for COVID-19, according to an email sent to employees Wednesday by the hospital’s interim CEO, Brad Simmons, and David Lubarsky, CEO of UC Davis Health.

The staff at UC Davis requested COVID-19 testing by the CDC, but because the patient didn’t fit the CDC’s existing criteria for the virus, a test wasn’t immediately administered, according to the email. The CDC then ordered the test Sunday, and results were announced Wednesday. Hospital administrators reportedly said in the email that despite these issues, there has been minimal exposure at the hospital because of safety protocols they have in place.

California health officials stressed that the health risk to the general public is still low and that COVID-19 has a low mortality rate despite spreading quickly. There have been no deaths in the U.S. "We have been anticipating the potential for such a case in the U.S., and given our close familial, social and business relationships with China, it is not unexpected that the first case in the U.S. would be in California," said Dr. Sonia Angell, director of the California Department of Public Health and state public health officer.

Community spread would represent a significant turn for the worse in the battle against the virus. To date, the United States has 60 known cases of the infection, with 59 among people who traveled to Asia or were close contacts of people who went there. The vast majority, 42, picked up the virus while quarantined on the Diamond Princess cruise ship off Japan. (Bernstein, McGinley and Sun, 2/27)

Hospitals receiving patients with flu-like symptoms have been asking people to detail their travel history or exposure to anyone who has recently traveled, Dr. Amy Compton-Phillips, the chief clinical officer and executive vice president of Providence St. Joseph Health, told CNN's Don Lemon. "Now we're going to have to be thinking, how do we change that strategy? Who all do we need to be testing for coronavirus? Right now, during flu season, that would be a lot of people and so we need to figure out how we can scale up the testing and the screening," she said. Providence St. Joseph Health operates 51 hospitals and more than 1,000 clinics across the country. (Moon and Maxouris, 2/27)

As the new coronavirus continues to spread in Europe, the Middle East and Asia — and Solano County recorded the first U.S. case unrelated to international travel, raising fears of a local outbreak — Bay Area hospitals are bracing for the possibility of large numbers of coronavirus patients at a time many are already stretched thin because of the flu season. Hospitals are doing practice runs for workers on how to triage and treat coronavirus patients, including putting on and taking off protective gowns, gloves and glasses, and are considering plans to potentially add isolation rooms or isolation wards if the need arises.

As countries across Asia and Europe continue to report new coronavirus cases, and more than four dozen cases are logged in the United States, Maryland officials say they are preparing for what might come. The officials outlined their readiness after the U.S. Centers for Disease Control and Prevention warned states and residents to start making plans for inevitable cases, though President Donald Trump denied at a Wednesday news conference that there was much of a threat. He said the risk remains low because of steps taken to close the border to potentially infected visitors. (Cohn, Knezevich and Bowie, 2/27)

With federal officials warning there will be a rapid spread of the coronavirus in the U.S., there were heightened concerns in Connecticut Wednesday about the state’s readiness to respond to the virus.

The coronavirus outbreak has already forced Hollywood studios to postpone several prominent films’ release in China. Now the epidemic is starting to disrupt production of the next slate of blockbusters. Practically all movie theaters in the world’s second-largest box office market have been closed since late January, an extraordinary measure Chinese health officials took as the number of new coronavirus cases, especially in major cities, grew rapidly.

More than 600 Massachusetts residents who traveled to China recently have voluntarily quarantined themselves at home while being monitored for the novel coronavirus, health officials revealed Wednesday.

Only one Massachusetts resident — a Boston student — contracted the illness, and he is recovering well in isolation at home, Bharel said. (Freyer, 2/26)

Stressing that the risk of contracting novel coronavirus remains low in Massachusetts, state public health officials said Tuesday that they are prepared for a potential outbreak. Tens of thousands of cases of the respiratory illness now known as COVID-19, caused by a new coronavirus first identified in Wuhan, China, have been diagnosed worldwide. (Lannan, 2/26)

The stark warning, from a federal health official, was a wake-up call for employers in Boston and around the country that hadn’t been focused on whether the coronavirus epidemic would make its way from China to the United States. “It’s not so much of a question of if this will happen anymore, but rather more of a question of exactly when this will happen,” Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said at a news conference Tuesday.
