The World Health Organization announced Thursday that it was declaring the coronavirus outbreak a “public health emergency,” setting in motion a plan for global coordination to stem the spread of the virus, which originated last month in Wuhan, China.

Chinese officials announced more than 3,100 new cases of the coronavirus,as the total number of people infected in China reached 9,720 as of Friday morning Beijing time, including nine cases in the self-governing island of Taiwan. The State Department heightened its travel advisory for China to Level 4: Do Not Travel due to the virus outbreak.

The United States confirmed a sixth U.S. case of the Wuhan coronavirus on Thursday, marking the first time the virus has spread from person to person in the United States.

With experts saying a vaccine is still a long way off, more international cases of the illness have appeared. Australia, Vietnam and South Korea all announced new coronavirus infections, while India and the Philippines had their first ones. Here’s what we know so far:

● Chinese officials say the death toll in the country has reached 213.

● More than 80 cases have been recorded outside China and the self-governing island of Taiwan, and four other countries have reported person-to-person transmission of the virus.

● Roughly 200 Americans evacuated from Wuhan landed in California on Wednesday, while the United States confirmed its first case where the virus had spread from person to person within the United States.

● WHO announced Thursday that it was declaring the outbreak a “public health emergency,” which legally requires states to ramp up their response to the crisis.

Infections also have been confirmed in Italy, France, Hong Kong, Japan, Nepal, Cambodia, Singapore, the United Arab Emirates, Vietnam, Taiwan, Canada, Thailand, Malaysia, Germany, Finland and Sri Lanka. We’re mapping the spread here

In companies and laboratories across the world, scientists are racing at record pace to build a vaccine against the coronavirus.

The National Institutes of Health projects that a vaccine it is working on with biotech company Moderna could be tested in humans in April. Scientists in Houston are pushing for another candidate vaccine — developed when a similar virus was the threat — to be thawed and formulated in vials for further testing. Yet another possible vaccine is being built at facilities in San Diego and Houston, with projections it could be tested in people by summer.

To scientists, the work to build a vaccine against the new coronavirus is advancing with speed they could barely have imagined a decade ago. At the same time, it’s not even close to quick enough to contain the spreading infection, but could be essential if the coronavirus rages on or resurfaces later….
