May 7 (Reuters) - China reported 13 new mainland COVID-19 cases on May 6, up from five cases a day earlier, the country's national health authority said on Friday.
The National Health Commission said in a statement all of the new cases were imported infections originating from overseas. The number of new asymptomatic cases, which China does not classify as confirmed cases, rose to 17 from 7 cases a day earlier.
The total number of confirmed COVID-19 cases in mainland China now stands at 90,739, while the death toll remained unchanged at 4,636.
