The US Centers for Disease Control and Prevention hopes to have every state and local health department testing for the novel coronavirus by the end of next week.

Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, announced the new goal in a press briefing Friday while also noting the coronavirus virus testing hiccups that have occurred so far.

"This has not gone as smoothly as we would have liked," she said.

Some testing kits initially sent to state and local labs were flawed, which delayed their ability to test for cases of the virus. Only a handful of labs other than the CDC could perform the test.

Officials have established the third of three testing components in the kits was responsible for providing "inconclusive results," and can be excluded from tests without impacting their accuracy, Messonnier said.

States that were previously able to validate cases using their original coronavirus testing kits can continue to use them, Messonnier said. States that were able to validate using two of the three testing components can use those tests as well, with revised instructions. Additionally the CDC has new test kits that can be ordered, which include the first two components.

"This will increase testing capacity at state and local health departments," Messonnier said.

There are now 62 confirmed cases of coronavirus in the US, according to the US Centers for Disease Control and Prevention.

• 44 are former passengers on the Diamond Princess cruise ship that docked in Japan after an outbreak and quarantine. Two of those cases were newly reported Friday.

• 3 are Americans recently repatriated from Wuhan, China, the center of the outbreak

• 1 patient at UC Davis Medical Center contracted the illness through unknown means

• Most of the other 14 patients had recently been to China or are spouses of someone who recently returned from China

Northern California patient in serious condition, official says

The CDC this week updated its testing criteria after a Solano County, California, woman wasn't tested for days after being hospitalized. The patient is in serious condition and has been intubated, according to California Rep. John Garamendi.

Her case has puzzled health officials, who say they have not been able to trace where she contracted the virus. The patient didn't have any relevant travel history, exposure to another known patient and wasn't one of the evacuees repatriated from China, officials said.

"This does appear to be a person who genuinely did acquire their illness in the community," Solano County Public Health Officer Dr. Bela Matyas said in a news conference Thursday.

The patient was transferred to UC Davis from a Northern California hospital last Wednesday but wasn't tested until Sunday, after doctors at UC Davis persisted in the request. Both hospitals said there was no initial testing administered because the patient didn't fit existing CDC criteria for coronavirus.

That guidance has now changed, CDC Director Dr. Robert Redfield said.

"As soon as that case was recognized, we met and we revised our case definition for persons under investigation," Redfield said. "Today, that has been posted (to the CDC website) along with a new health advisory that the recommendation should be when a clinician or individual suspects coronavirus, then we should be able to get a test for coronavirus."

With loosening guidelines, California said it was working with the CDC to quickly expand its testing capabilities.

"We have just a few hundred testing kits in the state of California, and that's surveillance testing as well as diagnostic testing," California Gov. Gavin Newsom said Thursday. "That's simply inadequate to do justice for the kind of testing that is required to address the issue head on."

The Solano County patient, who is being treated at UC Davis Medical Center, could be the first instance of "community spread" of the virus, the CDC said Wednesday.

"That suggests that the virus is out there in the community, and that means pretty much that everybody's at risk," Dr. Dean Blumberg, an infectious disease specialist at the center, told CNN affiliate KCRA. "We don't know who might be carrying it. We don't know who we can get it from."

But California officials maintain there is no major threat to the community at this time.

State health officials are also tracing who the Solano County patient may have interacted with, including the health care personnel who were exposed. In a letter to staff, UC Davis asked a number of employees to stay at home and monitor their temperature.

Some of the patient's family members were also in isolation, Matyas said.

More than 20 vaccines in development worldwide, WHO says

World Health Organization Director-General Tedros Adhanom Ghebreyesus said Friday the organization had "increased our assessment of the risk of spread and the risk of impact of COVID-19 to very high at a global level," referring to the WHO's formal name for the virus.

"The continued increase in the number of cases," he said, "and the number of affected countries over the last few days, are clearly of concern."

The risk assessment makes no "legal difference" in how countries should prepare for the outbreak, Dr. Mike Ryan, executive director of the WHO's Health Emergencies Programme, said Friday.

Rather, "raising the risk to very high is essentially reflecting what's actually happening at a global level," Ryan said, adding that it's a "reality check" for governments to prepare.

Most coronavirus cases can still be traced to known contacts or clusters of cases, Ghebreyesus said in a news conference in Geneva, and WHO does not yet see evidence that the virus is spreading freely.

"As long as that's the case," he said, "we have a chance of containing this virus."

There are more than 20 vaccines in development around the world, Ghebreyesus said, and several therapeutics are in clinical trials.

In the meantime, Ghebreyesus said people should be sure to wash their hands and regularly clean surfaces with disinfectant.

How the US is responding

By this weekend, 93 labs across the US are expected to have testing capabilities, US Sec. of Health and Human Services Alex Azar said. And as many as 70 companies are vying to develop a "bedside diagnostic" test for hospital use.

The US Food and Drug Administration also authorized the two-step test that will allow labs other than the CDC to test for the virus. A third step, which was causing inconclusive results, was eliminated, Azar said.

"Forty labs are qualified to already be doing that," he said.

And in Nebraska, a team of researchers are working to evaluate how effective the anvitiral drug remdesivir would be in treating people diagnosed with the virus, the National Institutes of Health said.

The clinical trial, taking place at the University of Nebraska Medical Center, in Omaha, will test the drug first on an American who was evacuated from the Diamond Princess cruise ship.

So far, there have been more than 83,300 confirmed cases of coronavirus across the world and at least 2,858 deaths -- the vast majority in China.
