A new spike in Asia, fueled by travel

Hong Kong, Singapore and Taiwan are confronting new waves of coronavirus cases, largely fueled by infected people who recently arrived from other countries, according to data compiled by The Times’s graphics team.

Singapore is also seeing a rise in community cases, with more than 400 in the past week linked to migrant worker dormitories.

None of these places had a single day with more than 10 new cases until March, but that changed in the past two weeks.

Students or expatriates returning from Europe or the U.S. account for a large share of the imported cases.
