The latest:
Chinese authorities have announced mass coronavirus testing in Wuhan as an unusually wide series of COVID-19 outbreaks reached the city where the disease was first detected in late 2019.
The provincial capital of 11 million people in central China is the latest city to undergo city-wide testing. Three cases were confirmed in Wuhan on Monday, its first non-imported cases in more than a year.
China has largely curbed COVID-19 at home after the initial outbreak that devastated Wuhan and spread globally. Since then, authorities have tamped down and controlled the disease whenever it pops up with quick lockdowns and mass testing.
The current outbreaks are still in the hundreds of cases in total but have spread much more widely than previous ones. Many of the cases have been identified as the highly contagious delta variant.
The National Health Commission said Tuesday that 90 new cases had been confirmed the previous day.
