Fourteen evacuated Americans were found to have the virus shortly before they boarded a chartered flight to the U.S. And the Japanese Health Ministry announced that 99 more cases had been confirmed on the ship, bringing the total to 454.

China signaled a delay of the most important political event of the year, the full meeting of the National People’s Congress — a sign of deepening anxiety within the Communist Party about the threat posed by the epidemic.

Here are the latest updates and maps of where the virus has spread.

The latest: The Tokyo Marathon was canceled for everyone except elite athletes, raising questions about what will happen to the Olympic Games in the city this summer. Separately, a prominent legal activist who accused China’s leader, Xi Jinping, of trying to cover up the outbreak was detained over the weekend, according to his friends.

Impact: Japan’s economy shrank in the last quarter of 2019, its worst contraction in more than five years. The results predated the coronavirus epidemic but were affected by a monthslong slump in Chinese demand for Japanese exports.
