On Saturday, Wuhan residents could travel by subway again. Before entering subway stations, they are required to scan QR codes by using widely available smartphone apps through which they must register by their real names so that their travel histories can be traced. As they get off the train, passengers have to scan the QR code posted in the carriage again in order to track which one they took.
All the measures are designed to make it easy to contact passengers in case infections are found on the subway network, the metro system authorities said.
Infrared thermometers have been installed in security-check areas to take passengers' temperatures. Those who have normal temperatures are allowed in, while those with fevers are subject to further temperature checks or quarantine.
Security personnel are being stationed on every train to guide passengers and provide them with needed services.
Jin Jing, head of the Hongshan Square Station, said all public areas and facilities in the station were thoroughly cleaned and disinfected before the subway resumed operation.
The station was ready to regain its former hustle and bustle after taking additional measures to protect passengers' safety, Jin said.
A passenger surnamed Chen, who works for a local hospital, said that when he took the subway and saw the passenger flow, he felt the city had awakened.
The city's subway system recorded some 183,200 trips on Saturday, according to the subway operating company, about 5 percent of the number this time last year.
