Coronavirus live updates: CDC says lab mix-up led to mistaken discharge of infected patient, Fed’s Powell ‘closely monitoring’ outbreak

This is a live blog. Check back for updates.

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. 

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.

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

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

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.

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

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

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

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

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

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

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.

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).
