HONG KONG, June 20 (Reuters) - The world's biggest gambling hub Macau began its second day of mass Covid-19 testing on Monday after dozens of locally transmitted cases were discovered over the weekend, with most businesses shut but casinos remaining open.

The testing of Macau's roughly 600,000 residents is expected to end on Tuesday as the Chinese-ruled former Portuguese colony adheres to China's "zero COVID" policy aiming to eradicate all outbreaks at just about any cost.
