SEATTLE — It's not her birthday for another month, but Ruby Francisco has been singing "Happy Birthday" a lot lately.
She does it every time she washes her hands.
"That's what they said to do," said Francisco, who owns a jewelry store here. "I tell my grandchildren to sing when they wash their hands so they do it right."
This is life in the age of the coronavirus: sifting through rumors, feverishly following updates and doing whatever it takes to avoid the virus, which has infected more than 89,000 people worldwide and killed more than 3,100 of them.
In Seattle, bracing for the coronavirus also means preparing for what could be a devastating economic impact. Business owners and residents have already seen a drop-off in tourists in areas of the city that heavily depend on foot traffic.
"It's like a ghost town," Francisco said about the famous Pike Place Market where she has her shop.
Nine people in the United Stated have died from COVID-19, the disease caused by the new coronavirus — all of them in Washington, which has reported 31 cases of the disease. Eight of the deaths were in an area of King County about 20 minutes from downtown Seattle, and one was in neighboring Snohomish County.
"This is a very fluid, fast-moving situation as we aggressively respond to this outbreak," Dr. Jeff Duchin, health officer for Seattle and King County Public Health, said in a statement.
King County health officials said the concern is particularly high for people who are 60 and older or who have compromised immune systems. Children do not appear particularly susceptible to the virus, which originated in mainland China.

As the death toll climbed Tuesday, Seattle Mayor Jenny Durkan, a Democrat, proclaimed a civil emergency. The declaration allows her to bypass regulations to increase city spending, contracting and borrowing to address the growing public health threat. It will also allow her office to close facilities and cancel events to prevent the virus from spreading further.

"We know that our city will need additional resources from our state and federal government," she tweeted. "We are looking to our partners to increase the availability of testing in a way that does not overwhelm the health care system, but meets the growing need."
She also asked residents to do their part by practicing good hygiene and making contingency plans at home and work.
Community members say that the move suggests that local leaders are taking the threat seriously but that it also points to hard times ahead for businesses dependent on tourism and pedestrians.
"It's our public duty to help people who are vulnerable," Tiia-Mai Redditt of Seattle said Tuesday while shopping for hand sanitizer at a Target. The store had been sold out for days, an employee said, and Redditt worried about a friend with a lung condition. She had already tried a nearby Whole Foods and a Trader Joe's.
"I've never seen downtown so empty," she said, referring to the streets, not just the shelves.

Across the street at Pike Place Market, Francisco wiped down the countertop at her jewelry store, Ruby's Seattle Gift Gallery. She usually keeps two doors open for customers. On Tuesday, one stayed closed because she was worried about germs.
"It's so scary," she said. "I'm going to start praying not just for a cure, but for the families in mourning right now."
