Evacuees from Wuhan arrive in U.S.

A plane carrying more than 200 Americans from the Chinese city that is the epicenter of a coronavirus outbreak landed in Alaska on Tuesday. The passengers, including diplomats and businesspeople, were to undergo medical screening before continuing on to their final destination in California. Here are the latest updates.

Chinese officials said today that at least 132 people had died from the virus and raised the number of confirmed cases to nearly 6,000.

Governments and businesses around the world issued fresh travel warnings on Tuesday, and Americans are now discouraged from visiting China. U.S. officials said the screening of travelers from Wuhan would be expanded to 20 ports of entry.

The details: Cases in Germany, Japan, Taiwan and Vietnam involved patients who had not traveled to China. No deaths have been reported outside China. Here’s what we know about the virus.

For perspective: The flu kills roughly 35,000 Americans every year. This season, it has already sickened an estimated 15 million Americans and killed 8,200, according to C.D.C. estimates.

Another angle: Bats are considered the probable source of the outbreak. Scientists have long struggled to understand how the mammals carry so many viruses without getting sick.
