SEATTLE — About 30 minutes south of the hospital caring for the man with the first confirmed U.S. coronavirus infection, some Chinese Americans in Seattle changed their plans for their biggest holiday of the year to avoid any chance of contact with someone who might be infected.

One woman, who declined to give her name, said she canceled her family’s restaurant reservations for Lunar New Year in favor of dinner at home. She said she doubted she’d be making a Chinese feast either. Out of an abundance of caution, she said she didn’t want to go to the Asian market to buy ingredients.

The Northwest Chinese School, with locations in Bellevue, Wash., and Seattle, sent out an email calling off weekend classes for preschoolers through adults. “We take the health of our students and families very seriously and think that this is the best course of action,” officials wrote.
