WUHAN: The ground-zero city of Wuhan is cautiously reopening after a two-month quarantine, but the birthplace of the global coronavirus pandemic is now on guard against a potential new threat: imported cases.

Travel restrictions have been loosened, with Wuhan’s busy train station officially resuming inbound services on Saturday and highways reopened as the unprecedented lockdown that kept more than 50 million people across Hubei province housebound is lifted.
