上海疫情仍处于初期阶段 - 2022年01月17日

Shanghai's COVID-19 outbreak remains at the "quite early stage" with a clear transmission chain under precise big data tracking, the city's top coronavirus expert has said.

All the new positive cases were found during screening for close contacts of an imported case. The number is very limited, said Dr Zhang Wenhong, head of Shanghai's COVID-19 treatment team and director of the National Center for Infectious Diseases.

"We've run ahead of the virus and created an ideal close-loop," Zhang said in an interview with CCTV news.
