SHANGHAI, Feb. 20 (Xinhua) -- The anti-epidemic efforts taken by Shanghai have proved effective as the city saw decreasing number of confirmed cases of novel coronavirus infection in recent days, a local official said Thursday.

Zheng Jin, a spokesperson with the Shanghai Municipal Health Commission, made the remarks at a press conference held by Shanghai municipal government.

The city is allowing enterprises to resume work and production in an orderly manner while it remains highly vigilant of the epidemic situation, Zheng said.

"At present, the traffic volume and city commuting in Shanghai have gradually returned to normal," she said.

The city is also using big data and other information-based technology to manage the flow of people.
