Several countries have arranged charter flights to take their nationals home after they leave the boat. Here are the latest updates and maps of where the virus has spread.

In Europe: With about 40 confirmed cases in the region, fear itself is proving contagious; people and places associated with the illness are facing a new social stigma.

Economic impact: HSBC, one of Hong Kong’s most important banks, said Tuesday it would cut 35,000 jobs over the next three years, and U.S. stocks fell a day after Apple said it would miss its sales forecast because of the disruption in China.

Perspective on China: Li Yuan, our New New World columnist, writes, “Beijing has shown the world that it can shut down entire cities, build a hospital in 10 days and keep 1.4 billion people at home for weeks. But it has also shown a glaring weakness that imperils lives and threatens efforts to contain the outbreak: It is unable to work with its own people.”
