China coronavirus cases grow; 11,791 confirmed and 259 deaths
The number of confirmed cases of novel coronavirus in China grew to 11,791 with 259 deaths as of the end of the day Friday local time, China's national health commission said on its website.
That's an increase in the national number from 9,692 confirmed cases and 213 deaths in China reported as of the end of the day Thursday.
Earlier Friday, Hubei province's local health commission reported 11,067 confirmed cases and 258 deaths, and the national numbers show larger total figures. The epicenter of the new coronavirus outbreak is the city of Wuhan, which is in Hubei province.
The 46 new deaths were mostly in Hubei province, with 45 there, the national health commission said. The other new death was in the city of Chongqing, which is southwest of Hubei. There are also nearly 18,000 suspected cases in China.
All of the deaths have been in China and the vast majority of confirmed cases are also in the country, although there are also confirmed cases in other countries, including the United States, where there are seven confirmed cases of the virus, also known as 2019-nCoV, health officials there have said. — NBC Beijing
7th case of new coronavirus confirmed in U.S.
An adult male returning from China has been diagnosed with the novel coronavirus in California, the Santa Clara county public health department said Friday. The Bay area public health department was notified by the Centers of Disease Control and Prevention that the resident was confirmed to have the respiratory disease, Dr. Sara Cody, director of the County of Santa Clara health department said during a press briefing Friday.
It's the seventh confirmed case in the U.S. and the third case in California.
The patient had been in Wuhan, China and Shanghai and returned to California on Jan. 24 through the San Jose airport. He became ill upon his return, Cody said.
"Since his return, he has only been at home. He came into contact with a very few individuals after returning home." Cody said. "His only travel has been to seek care."
The patient has not been very ill and has not required hospitalization. He has been self-isolating in his home. "He will be followed closely at home until he's no longer infectious," Cody said.
As part of the investigation, the Santa Clara county health officials are working with the CDC to find anyone who may have been exposed to the patient, including individuals at the health care facilities or other passengers during his air travel, Cody said.
Cody sought to calm concerns about the risks of the disease's spread in the community, noting that health officials had been preparing for weeks for the possibility of a case.
"We don't have evidence to suggest that the coronavirus is circulating in the Bay area, Santa Clara county or northern California," she said during the briefing. "This one case does not change the risk to the general public." The CDC confirmed the 7th case in California. — Jane Weaver
U.S. declares public health emergency
Starting Sunday at 5 p.m. ET, all passengers on flights to the United States who have been in Hubei province in China in the last 14 days will be subject to up to 14 days of quarantine. The city of Wuhan, the epicenter of the outbreak, is located in Hubei.
Any U.S. citizen who has been in the rest of mainland China will be actively screened at one of seven airports for risk and evidence of symptoms. If no symptoms are detected, the individuals will be allowed to complete their travel home and will be monitored by local health departments in isolation at home.
At the same time, the White House announced that it will not allow anyone who has been in China recently to enter the U.S. because they may pose a risk of transmitting the coronavirus. Foreign nationals, other than immediate family of U.S. citizens and permanent residents, who have traveled to China within the last 14 days will not be allowed to enter the U.S. during this time.
The seven airports are in New York, San Francisco, Seattle, Honolulu, Los Angeles, Chicago and Atlanta. — Erika Edwards
Federal quarantine ordered for Americans flown from Wuhan
The CDC said Friday that all 195 Americans from Wuhan, China, who recently landed in California are now under federal quarantine for 14 days.
It's the first time in 50 years that the CDC has issued such a quarantine, which was for smallpox.
The increase of cases in China, which sits at almost 10,000 people, helped spur the CDC to act.
"We would rather be remembered for overreacting than underreacting," Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, said during a call with journalists. "While we recognize this is an unprecedented action, we are facing an unprecedented health threat." — Erika Edwards
Dow drops more than 500 points
The Dow dropped 525 points as of Friday afternoon, after United, Delta and American suspended all flights between China and the U.S. The S&P 500 was down 1.5 percent, while the Nasdaq Composite dipped by just over 1 percent.
Many market watchers attributed the decline to growing concerns about the coronavirus.
Airlines, hotels, and other travel-related stocks have been hit hardest as China locked down cities, shuttered factories and businesses, encouraged employees to work from home, and implemented severe transport restrictions to help stop the spread of the virus.
The economic fallout has also hit the luxury goods sector and global tourism, since the coronavirus outbreak comes during China's Lunar New Year holiday, in which many Chinese people travel and buy gifts.
U.S. companies such as Apple, Alphabet and Nike, which have the greatest exposure to China, also saw their stocks fall. — Lucy Bayly

Delta said its suspension will start Feb. 6 and last through April 30.
United also said it would suspend some flights to China in part because of a decline in demand.
