Authorities in China on Friday said more than 10 million people in the northern port city of Qingdao have been tested for COVID-19 after a hospital outbreak there was blamed on "inappropriate disinfection."
Testing is set to continue to cover 11 million people.
A total of 13 cases have been discovered in the city, but none since the mass testing program was launched earlier this week, according to health authorities.
The latest cluster of infections represents the first locally transmitted cases reported in China in about two months.
It appeared to be linked to a CT room at the Qingdao Chest Hospital.
Officials said the possibility of community transmission outside the hospital had been ruled out.
China's National Health Commission reported 24 new coronaviurs cases on Friday, all of them imported.
