The number of COVID-19 cases has crossed the 100,000 mark, as case counts in Iran and South Korea continue to increase and Americans, worried about a cluster of infections in Washington state, begin preparing for the possibility of disruption.

There are 102,472 COVID-19 cases and at least 3,491 deaths, while 57,463 people have recovered, according to the most up-to-date figures from the Johns Hopkins Whiting School of Engineering’s Centers for Systems Science and Engineering on Saturday. In the U.S. there are 340 cases and 12 deaths.

Amazon.com Inc. AMZ, +0.23% , which employs 50,000 people in the Seattle/Bellevue area, told employees to work from home if possible through March, as did Facebook Inc. FB, +0.86% and Microsoft Corp. MSFT, -0.49% . The Fred Hutchinson Cancer Research Center in Seattle issued a mandatory work-from-home policy, starting March 5 and ending March 31.

Some companies in the San Francisco Bay Area have implemented similar policies.

At the same time that employers are telling workers to prepare to work from home or to implement other contingency plans, a number of grocery chains have reported an uptick in sales of canned goods, paper products, and cleaning supplies. Costco Wholesale Corp. COST, -0.09% , which is seeing shopping frequency and sales levels increase, including a “big uptick in sales” the last week of February, has placed quantity limits on some products, CFO Richard Galanti said during an earnings call.

In recent days customers are spending more money on water, hand sanitizer, hand soap, paper products, box dinners, and soups, according to remarks made by Kroger Co. KR, +0.12% CEO Rodney McMullen on Thursday. And BJ’s Wholesale Club Holdings Inc. BJ, +2.25% also said customers are “stocking up on cleaning supplies and canned food.”

In countries that have reported sizable outbreaks of the novel coronavirus, the numbers continue to grow. Iran has 4,747 cases and 124 deaths; Italy has 4,636 cases and 197 deaths; and South Korea has 7,041 cases and 44 deaths.

The outbreak of COVID-19, which was first identified in December in Wuhan, China, has caused dips in the markets, disrupted supply chains that have become increasingly reliant on China, and negatively impacted travel operators like airlines and hotels as governments and employers have put into place new travel restrictions.

Here’s what companies are saying about the impact of COVID-19:

• Starbucks Corp. SBUX, -0.19% said it was already “showing early signs of recovery” in China and that U.S. sales are still strong despite the coronavirus. “To date, there are no perceptible signs of COVID-19 impact on our U.S. business, which accounted for approximately 65% of total consolidated revenues in the first quarter of fiscal 2020,” the coffee chain said in a financial filing.

• Skechers USA Inc. SKX, -1.63% told investors the impact of COVID-19 had worsened since it last updated investors when it reported earnings on Feb. 6. Skechers offered guidance at that time for first-quarter sales of $1.400 billion to $1.425 billion, and earnings per share of 70 cents to 75 cents. “Things definitely have deteriorated to a degree,” CFO John Vandemore told investors at a UBS conference on Thursday. He also said the big change is now coming in European countries that have experienced clusters of the illness, with Italy closing schools and universities.

• ON Semiconductor Corp. ON, +0.06% issued a revenue warning for the first quarter on Friday, due to the change in business conditions being created by the coronavirus. The Apple Inc. AAPL, -0.93% supplier now expects revenue to range from $1.275 billion to $1.325 billion, compared with prior guidance of $1.355 billion to $1.405 billion, issued on Feb. 3. “We saw soft order trends in China in the weeks following Lunar New Year holidays, but orders have since picked up, and we have not seen any significant cancellations of orders,” CEO Keith Jackson said in a statement.

• Hugo Boss AG BOSS, -0.37% said it closed about 60% of its stores in February. The stores that remained open reported traffic declines of 80% or more. “Since the beginning of February, we are recording a softer local consumption as well as a noticeable decline in sales to Chinese tourists and other Asian markets, including Japan and South Korea, but also in some European countries, Italy, obviously being one of them,” CEO Mark Alexander Langer said during an earnings call.

• Shares of cruise ship operators took double-digit dives Thursday to their lowest closes in years, as the global spread of the coronavirus fueled fears of a drop in travel demand. Royal Caribbean Cruises Ltd.’s RCL, -1.45% stock plummeted 17.1% to $65.78, Carnival Corp. CCL, -2.83% shares tumbled 14.1% to $27.87, and shares of Norwegian Line Holdings Ltd. NCLH, -1.97% sank 13.4%, which was the worst day for investors since they started trading in January 2013.
