4:05 pm: Outbreak could affect Airbnb’s IPO, WSJ reports

The company announced publicly last year that it “expects to become a publicly-traded company during 2020.” The Wall Street Journal reported that Airbnb likely won’t go public until the third quarter of this year. That timing could be affected by the coronavirus outbreak that has swept across China, one person cited in the report said. China is a key growth area for Airbnb. The company’s co-founder, Nathan Blecharczyk, currently serves as chairman of Airbnb China. — Feuer

3:51 pm: Germany confirms two new cases of coronavirus, raising overall number to 16

Germany confirmed two more cases of coronavirus in the southern state of Bavaria, raising the overall number of known cases in Europe’s most populous country to 16. The two new cases of coronavirus are related to infections among staff at a company in the Starnberg district west of Munich, the Bavarian health ministry said. Car supplier Webasto said last month a Chinese employee had tested positive for the virus upon returning to China following a visit to the headquarters near Munich. The employee apparently infected several German colleagues during the visit. — Reuters

3:13 pm: The coronavirus appears to be sparing one group of people: kids

The new coronavirus that has already killed more people than the 2003 SARS epidemic appears to be sparing one population group: kids. Of the more than 43,100 people it’s infected since Dec. 31, World Health Organization officials say the majority are over 40 years old and it’s hitting those with underlying health conditions and the elderly particularly hard. About 80% of people who died from the virus in China were over the age of 60, and 75% had pre-existing conditions such as heart disease or diabetes, according to a recent report from China’s National Health Commission. A small study published Jan 30 in the peer-reviewed medical journal The Lancet found that the average age of coronavirus patients was roughly 55 years old. The study looked at 99 patients at Jinyintan Hospital in China from Jan. 1 to Jan. 20. — Lovelace

2:25 pm: Money manager says the outbreak is ‘one of the biggest risks to the market’

Wilmington Trust’s Meghan Shue believes the coronavirus outbreak is a huge wildcard for Wall Street. If the infectious disease, recently named COVID-19, keeps spreading, stocks are in trouble, she said. “Coronavirus remains one of the biggest risks to the market at this point,” she told CNBC’s “Trading Nation.” “I don’t think we know enough to know whether we’re out of the woods as of yet.” Shue, who has $113 billion in assets under management, expects elevated market volatility until number of coronavirus cases peak. Historically, she finds the market doesn’t bottom until similar outbreaks reach a top. — Landsman

1:44 pm: BofA says investors shouldn’t compare the coronavirus outbreak to SARS

As tempting as it may be to compare the coronavirus outbreak to the 2003 SARS epidemic, a number of Wall Street analysts warn this is a dangerous game since the broader economic backdrop was very different in the early 2000s than it is today. “SARS: unfortunately, the analogy doesn’t work,” Bank of America global economist Ethan Harris said. “A broad consensus has emerged that the SARS episode offers an imperfect but reasonable historical analogy for what is happening now … We think the SARS episode is more misleading than useful.”

1:30 pm: Coronavirus likely jumped from bats to another host before infecting humans

The new coronavirus that emerged from a seafood market in Wuhan, China likely originated in bats and then jumped to an “intermediate host” before infecting humans, World Health Organization officials said. Scientists are running tests on various animals, but have so far not found the host responsible for the outbreak, Dr. Sylvie Briand, head of WHO’s Global Infectious Hazard Preparedness division, told reporters at a news conference at the agency’s headquarters in Geneva. Studies are ongoing because they are checking a number of animal species, so it takes some time,” Briand said.

1:11 pm: American Airlines extends China cancelations until late April 

American Airlines is extending the suspension of its mainland China and Hong Kong service until late April, citing low demand as coronavirus continues to spread. The carrier said it now plans to resume its flights to mainland China from Los Angeles and Dallas/Fort Worth in April 25, almost a month later than it previously targeted. Dallas/Fort Worth-to-Hong Kong will resume on April 24, and a day later from Los Angeles. The move follows a similar adjustment by partner carrier British Airways. — Josephs

12:43 pm: Google interest in coronavirus spikes

Online search interest in the term “coronavirus” peaked around Feb. 1, but online interest in the outbreak remained high, according to data from Google Trends, Google’s source for data about queries made on the search engine. The data in the chart below shows search interest relative to the highest point in the chart, meaning that a value of 100 is “peak popularity” for the search term, while a value of 50 means that the term is half as popular. The search term “coronavirus” was most popular in Singapore, followed by Canada and Australia, from the period of January 18 to February 8, the most recent data point available. The United States ranked 20th in search interest among the countries listed. Notably, Google is not available in China, the epicenter of the outbreak, and thus data for Chinese searches is not available. According to Google, users searching for “coronavirus” also frequently searched for “Cure,” “Epidemic,” and “Quarantine.” — Rattner 

12:29 pm: Hilton closes 150 hotels across China

Hilton has closed 150 hotels in China, leaving 33,000 rooms unoccupied. CEO Christopher Nassetta told investors the outbreak could hurt the travel industry for up to a year, based on what happened with the 2003 SARS epidemicl. The company will take a $25 million to $50 million hit for the year to its profit, before taxes and interest, among other things. However, the company said it has yet to see any cancellations for the 2020 Tokyo Olympics because of the virus. — Miller

11:42 am: Facebook, Cisco pull out of Mobile World Congress

Facebook and Cisco are both pulling out of the Mobile World Congress, following other big tech companies including Intel, Amazon, and Sony. The annual event typically attracts more than 100,000 delegates from 200 countries across the world. The conference is scheduled for Feb. 24 to 27 in Barcelona, Spain. “We will continue to collaborate with the GSMA and our partners and thank them for their efforts,” a Facebook company spokesperson told CNBC. A Cisco spokeswoman told Reuters the company was “extremely disappointed,” but “we believe this is the right decision given the current circumstances.” — Kim

11:15 am: CDC says lab mix-up led to mistaken discharge of an infected patient

A mix-up in the lab allowed an infected patient that had been evacuated from China to leave the hospital and intermingle with other evacuees quarantined at a military base, Dr. Anne Schuchat, a top official at the CDC, told reporters in Washington. “It turns out there was probably a mix up and the original test wasn’t negative,” she said. Four evacuees at Marine Corps Air Station Miramar in San Diego had been in federal quarantine after showing symptoms of the virus. After testing negative for the virus, they were returned to the base on Sunday where they joined more than 200 people who are under a 14-day quarantine. The CDC discovered that one of the patients actually tested positive for COVID-19 and was returned to the hospital where they are under isolation.

10:46 am: Under Armour estimates up to $60 million sales hit

Under Armour said Tuesday that it expects the coronavirus outbreak in China to lower sales by roughly $50 million to $60 million during the fiscal first quarter. The impact could grow worse, it said, should the situation worsen. Under Armour told analysts that factories in China continue to stay closed, and timelines continue to change for when they might reopen. “We think it’s reasonable to expect industry-wide delays in terms of delivery around the world — including potentially missed shipment[s] and service windows, and the need for increased air freight and additional measures at ports that could create unforeseen congestion,” CEO Patrik Frisk said.

10:40 am: Automakers resume production in Asia

Automakers are continuing to resume production in China and other impacted areas after an extended holiday shutdown due to the coronavirus. Hyundai Motor said it plans to “gradually begin increasing production” starting Tuesday at seven of its plants in South Korea. The facilities were idled last week because of a lack of parts from suppliers in China. The plants will reopen based on the availability of parts, according to the South Korean-based automaker. Ford Motor late-Monday also said it is continuing to gradually resume production at its plants in China. — Wayland

10:36 am: World Health Organization names the new coronavirus: COVID-19

The flu-like coronavirus that has sickened more than 43,100 people in over two dozen countries now has a name: COVID-19. The CO stands for corona, the VI for virus and the D for disease, Tedros Adhanom Ghebreyesus, director-general of the WHO, announced at news conference at the agency’s headquarters in Geneva. Tedros said the agency needed to find a name that did not refer to a geographical location, animals, an individual or a group of people. — Lovelace

10:16 am: WHO officials hold press conference at Geneva research forum

World Health Organization officials are holding a press conference to update the public on the coronavirus outbreak, which has killed more people than SARS. The WHO’s global research and innovation forum met for the first time Tuesday at the organization’s headquarters in Geneva. Tedros Adhanom Ghebreyesus, director-general of the WHO, announced the forum last week. Attendees include representatives of China and other member states, infectious disease experts, bioethicists, and major research funders, according to the preliminary agenda. The mission of the forum is to establish a common understanding of the virus and to agree upon research priorities and framework moving forward. The forum will continue through Wednesday.

9:55 am: Toymakers brace for coronavirus hit

Analysts at UBS said the outbreak will potentially disrupt supply chains for major toy companies, adding that about 85% of the U.S. toy industry’s sales are supplied from China. While toymakers like Hasbro and Mattel have worked to decrease their reliance on factories in the region, more than half of their toys are currently produced in China. During Hasbro’s fourth-quarter earnings call, Deb Hancock, senior vice president of investor relations, said “it’s challenging to quantify the potential magnitude at this time, as it will depend on how long it takes to contain the outbreak.” The company did not provide an estimated financial impact, but Hancock said “If it takes a significant period of time to control, there could be a larger impact of our business.” Mattel reports earnings Thursday. — Sarah Whitten

8:53 am: China’s Huanggang says virus situation in city remains severe

The Communist Party boss of China’s Huanggang city, which has been hard hit by the coronavirus outbreak, said the virus situation in city was still severe.

8:50 am: Powell stresses that the Fed is ‘closely monitoring’ coronavirus

Federal Reserve Chairman Jerome Powell said the U.S. central bank is “closely monitoring” the new coronavirus, its impact on China and the effect that it could have on global economic growth. In his semiannual testimony before Congress, Powell said the new threat comes just as trade uncertainties have diminished, though the U.S. economy appears “resilient” to global headwinds. — Cox

8:10 am: Fast-tracking vaccine still means at least one year

British scientist Dr. Robin Shattock told CNBC the public shouldn’t expect a coronavirus vaccine to hit the market until early next year, despite recent advances. “The closest we’ll get to making this available will be early next year, or later,” Shattock, head of mucosal infection and immunity at the Department of Medicine at Imperial College London, said on “Squawk Box.” “It still requires a lot of testing to see if these vaccines are safe and then see if they work,” he added. Shattock is part of a team in the U.K. exploring potential coronavirus vaccinations. The group has started animal testing and hopes to move on to human testing “within a period of months,” he said. — Bursztynsky

8 am: Wall Street shrugs off coronavirus fears

U.S. stock index futures pointed to a higher open on Tuesday as Wall Street shrugged off concerns over the economic impact of the coronavirus outbreak. Around 7:45 a.m. ET, Dow Jones Industrial Average futures were up 87 points. S&P 500 and Nasdaq 100 futures traded higher as well. Fears over the economic fallout from the outbreak have also been offset by positive economic indicators. Jobs data released last week easily beat analyst expectations while U.S. manufacturing and services activity show signs of improvement. — Imbert, Smith

7:51 am: Robot with coronavirus advice hits Times Square

A 5-foot tall robot with a friendly face rolled into Times Square on Monday to help provide information about the new coronavirus to tourists. Curious passersby stopped, filled out a short questionnaire on an iPad-like touch screen attached to the robot’s chest, and even had a conversation with the machine. Promobot was created by a Philadelphia-based start-up that makes autonomous service robots for businesses and is run by a group of Russians. “We did a special software to detect coronavirus symptoms,” the company’s chief business development officer, Oleg Kivorkutsev, told Reuters. — Reuters

7:30 am: 13th case confirmed in the US among China evacuees

The first confirmed case of novel coronavirus has been found among hundreds of people who were evacuated from China to military bases around the United States, it was reported Monday. Four evacuees at Marine Corps Air Station Miramar in San Diego had been in federal quarantine after showing symptoms of the virus but on Sunday, federal health officials said the people had tested negative and were sent back to the base, where they joined more than 200 people who are under a 14-day quarantine. On Monday morning, however, officials with the Centers for Disease Control and Prevention informed county health officials that “further testing revealed that one of the four patients tested positive” for novel coronavirus and the person was returned to hospital isolation, UC San Diego Health said in a statement. Another evacuee from Miramar also was hospitalized for evaluation Monday afternoon, UC San Diego Health said. “Both patients are doing well and have minimal symptoms,” the statement said. This is the seventh confirmed case of novel coronavirus in California and the 13th in the United States. — Associated Press

5:30 am: China’s top virus expert reportedly says outbreak may peak this month

China’s fast-spreading coronavirus may peak in February, before cases then start to plateau and ease over the coming months, Beijing’s top economic adviser told Reuters. Zhong Nanshan, a leading epidemiologist who become known around the world for his role tackling the SARS epidemic in 2003, said the situation in China was already showing signs of improving, pointing to the number of new cases falling overnight. He added that he believes the outbreak would peak either by the middle or the end of February before the number of cases would then start to fall. Zhong had previously predicted an earlier peak for the coronavirus, Reuters reported.

4:25 am: WHO chief says outbreak ‘holds a very grave threat’ for world

The director-general of the World Health Organization has reportedly warned that while almost all of the confirmed coronavirus cases are in China, the outbreak constitutes a “very grave threat” for the rest of the world. “With 99% of cases in China, this remains very much an emergency for that country, but one that holds a very grave threat for the rest of the world,” Tedros Adhanom Ghebreyesus said during opening remarks of a meeting between more than 400 researchers and national authorities, Reuters reported Tuesday. His comments come less than 24 hours after he told reporters at the U.N. health agency’s headquarters in Geneva that cases detected outside China “could be the spark that becomes a bigger fire.”

As of Monday night, China’s National Health Commission reported that a total of 42,638 cases had been confirmed in the country, with 1,016 deaths. (See 8:17 a.m. update).
