After a person in California who was reportedly not exposed to anyone known to be infected and had not traveled to countries where the virus is circulating - was infected.
A problem with one ingredient in test kits that the federal Centers for Disease Control and Prevention distributed to labs around the country had created a frustrating bottleneck in testing, requiring most testing to occur at the CDC in Atlanta.
In a statement released Wednesday, UC Davis Health said the patient was being treated with "airborne precautions and strict caution precautions".
"The recommendation should be when a clinician or public health individual suspects coronavirus, then we should be able to get a test for coronavirus, so that's the current guidance that went out today", said Redfield.
If that's the case, Compton-Phillips says, it's "problematic" that there are only 12 USA labs other than the CDC with working coronavirus test kits.
President Donald Trump on Wednesday evening appointed Vice President Mike Pence as the new head of the task force coordinating the battle against the virus.
California officials said this protocol had to be expanded in light of the "inevitable" local spread within the United States. In a statement provided to Fox News, Aimee Brewer, the president of NorthBay Healthcare Group, said the patient "at no time fit the existing CDC [Centers for Disease Control and Prevention] criteria for COVID-19, and therefore a test was not immediately administered".
Park said while the state health department sends samples to the CDC for the coronavirus test, doctors also should check patients for other illnesses, such as the flu.
There are 81,000 confirmed cases of the coronavirus worldwide, and almost 3,000 people have died from it.
Earlier U.S. cases included 14 in people who traveled back 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 who were evacuated by the federal government to the U.S. from where the ship was docked in Japan. The CDC on Tuesday warned Americans that community spread is nearly certain to occur, and to prepare for significant disruption in their daily lives.
More than 80 000 people have been infected worldwide and 2 800 have died, mostly in China, where the virus originated late previous year.
At a press conference held yesterday, President Donald Trump announced that Vice President Mike Pence will lead the United States response to COVID-19. The agency said only that the person lived in California.
