The coronavirus can survive on frozen food packaging, Chinese officials have said after discovering a city outbreak linked to frozen fish.
The Chinese Center for Disease Control and Prevention (CDC) detected and isolated a living sample of the coronavirus on the outer packaging of frozen cod. Only traces of the pathogen had been found on frozen packaging before now.
It was imported to the eastern city of Qingdao, which has been hit by a fresh cluster of cases linked to two dock workers. The men, who were diagnosed in September, were responsible for unloading frozen seafood at the port.
