The U.S. will soon require COVID-19 testing for travelers from China. The U.S. joins a few other nations imposing travel restrictions because of a surge of infections in China. The increase in cases follows the rollback of China’s strict anti-virus control. Beginning Jan. 5, travelers to the U.S. from China will have to take a COVID-19 test no more than two days before they travel and provide negative results before they board their flights. The U.S. action announced Wednesday is a return to requirements for some international travelers. The Biden administration lifted the last of such mandates in June.
