6 pm: Google is showing ads for anti-coronavirus products, despite policy banning them
As coronavirus cases continue to spread around the globe, online ads for hand sanitizers, gloves, masks and other products purporting to prevent sickness were rampant, and companies are having a hard time enforcing policies that ban such ads. As of Wednesday afternoon, Google is showing many such ads, even though it has a policy that prohibits ad content that capitalizes off the coronavirus, according to a spokesperson. Products promising to prevent coronavirus are appearing in sponsored shopping lists for product searches and in Google display ads that show up on third-party sites. Google and other major tech companies such as Amazon have seen third parties move quickly to use their platforms in attempts to make money from coronavirus concerns and have struggled to stay ahead of the violators. It's the latest example of how the operators of massive-scale online platforms sometimes lack the tools or personnel to keep up the never-ending game of whack-a-mole against people who exploit them. -- Graham
5:26 pm: Campbell Soup is increasing production to prepare for coronavirus demand
Campbell Soup CEO Mark Clouse said Wednesday that the company is increasing soup production in response to the coronavirus outbreak. "We made the decision last week to up production in certain areas where we're using a little bit the analogy of weather or natural disasters," Clouse said on CNBC's "Closing Bell." "Where do we see demand coming in a greater rate? And we've upped that level of production to be able to maximize our inventory to be prepared for whatever unfolds here." Consumers, particularly those closest to virus clusters, have been stockpiling canned soup and other shelf-stable foods as more cases of the disease are reported in the U.S. Hand sanitizer and cleaning supplies have also seen their sales surge, presenting a problem for grocery stores and retailers, who may be unprepared by the sudden swing in demand. -- Lucas
5:15 pm: DHS employee tests positive for coronavirus
A Department of Homeland Security employee has tested positive for the coronavirus, DHS press secretary Heather Swift said in a statement Wednesday. The employee, one of at least six people in Los Angeles who have tested positive for COVID-19, worked last month as a medical screener checking passengers arriving from China at LAX, DHS said. "Late last night, DHS headquarters was alerted to a situation where one of our contracted medical professionals conducting screenings at LAX international airport had tested positive for COVID-19," the statement said. "This individual is currently under self-quarantine at home with mild symptoms and under medical supervision. Their immediate family is also under home quarantine." -- Bhattacharjee
5 pm: NIH official questioned about WHO mortality rate
NIH official Dr. Anthony Fauci told lawmakers the mortality rate for COVID-19 could change depending on how many people ultimately fall ill and die from the virus. World health officials said Tuesday that the current mortality rate was around 3.4%, significantly higher than previous estimates. "As a group, it's going to depend completely on what the factor of asymptomatic cases are," he said, adding the more asympotmatic cases, the lower the mortality rate. "What we're hearing right now on a recent call from the WHO this morning is that there aren't as many asymptomatic cases as we think, which made them elevate, I think, what their mortality is," he said. "I'm torn. If we get enough data to have a big [numerator] it's gonna be bad news for us." -- Hirsch, Higgins
4:53 pm: House passes $8.3 billion emergency spending plan

It's increasing the frequency of sanitizing and cleaning at all its company-operated stores to help prevent the spread of germs and pausing the use of personal cups and "for here" ware in stores. Starbucks says it's also put in place procedures for how to report and support team members that may say they've been impacted by the virus, including steps for closing stores, if needed. The coffee giant has restricted all business-related air travel both domestic and international through March 31, and modified or postponed large meetings at offices in the U.S. and Canada. Read the full memo here. -- Kate Rogers
4:34 pm: US should give China leeway in implementing trade deal, Republican senator says
Washington needs to give China some leeway in implementing a phase one trade deal given a downturn in the Chinese economy caused by the fast-spreading coronavirus, U.S. Senate Finance Committee Chairman Chuck Grassley said.
Grassley, R.-Iowa, told Reuters in an interview that he saw no evidence that China intended to try to escape its commitments under the trade deal to sharply increase its purchases of U.S. farm goods, manufactured products, energy and services.
But the coronavirus could require some adjustments and would likely delay the start of negotiations on a phase two trade agreement, he said.China's moves to reduce some tariffs on U.S. goods and allow U.S. inspections of their food showed they were acting in "good faith," Grassley added. -- Reuters

No conference speakers canceled, but UBS managing director and retail analyst Michael Lasser said some attendees traveling from Europe didn't attend due to coronavirus-related travel restrictions. UBS added a speaker: Dr. David Sidebottom, director of infectious disease at Lowell General Hospital. And one company, eyewear retailer National Vision, presented via webcast instead of in-person. Its Chief Financial Officer Patrick Moore remotely addressed investors and executives from a conference room table set up with a laptop, bottle of water and a giant bottle of hand sanitizer. -- Repko

Colorado has yet to report any cases of the new coronavirus in the state, yet consumers there are already stockpiling more powdered milk and cans of soup than in Washington state, where at least nine people have died due to the virus.
But Coloradans aren't the only ones stocking up on canned goods and cleaning supplies.
Hand sanitizer sales have skyrocketed 619% nationwide in the week ending March 1, according to data from marketing firm Catalina, which compared the sales of 33 products to the same period a year ago. Disinfecting cleaners and wipes have seen their sales more than double. Grocery store and retailers are trying to prevent shortages from "panic buying" as more cases of the virus are confirmed in the United States. -- Lucas

2:05 pm: HHS clarifies US has about 1% of face masks needed for 'full-blown' pandemic
The Department of Health and Human Services clarified that the United States has about 1%, not 10%, of the required respirator masks that would be needed for medical professionals if the COVID-19 outbreak were to erupt into a pandemic here. The agency said its pandemic planning assumptions estimate the U.S. health-care system will need up to 3.5 billion N95 respirator masks over a year. The Strategic National Stockpile, the nation's emergency stockpile of drugs and medical supplies, currently holds approximately 12 million medical-grade N95 respirator masks and 30 million surgical face masks, according to an HHS spokesperson.

Credit card travel insurance has a lot of quirks when it comes to what is and what isn't covered. In most cases, travel insurance covers prepaid, non-refundable travel expenses including passenger fares, tours and hotels. Precautionary cancellations aren't likely to be covered. So if you cancel your vacation because you're worried about potentially catching COVID-19, there is a slim chance your credit card travel insurance will provide reimbursement. —White
