In China, officials struggling to contain the spread of the coronavirus have delayed the start of the soccer season for months, and at least one top-division team has been marooned in the Middle East for weeks, unable to return from a preseason training camp.

In South Korea, fans attending matches earlier this month were checked for fever before being allowed inside stadiums, and masks were ubiquitous in the stands in Japan recently — until Tuesday, when officials announced that there will be no league play until at least mid-March.
