BEIJING – The recent COVID-19 cases in Anhui and Liaoning provinces contracted the novel coronavirus via individuals or articles from abroad, said the Chinese Center for Disease Control and Prevention (China CDC) Thursday.

The actual infection source of COVID-19 cases in Anhui and Liaoning is still under investigation, said Wu Zunyou, chief epidemiologist at the China CDC, at a press conference in Beijing.

As there were no local transmissions recently, the virus must have come from infected individuals or contaminated articles from abroad, he said.

Considering the result of screening tests in Anhui and Liaoning provinces, the infection scale will not be as serious as earlier this year, said Wu Zunyou, chief epidemiologist at the China CDC

"The genetic sequence of the COVID-19 viruses found in the Anhui and Liaoning cases were the same. We believe the cases were along the same transmission chain," Wu said.

Considering the result of screening tests in the two provinces, the infection scale will not be as serious as earlier this year, he said.
