China launches app to check proximity to coronavirus

China has launched out a mobile app enabling people to check whether they are at the risk of catching the coronavirus.

The "close contact detector" app, released on February 8, lets users scan a QR code via mobile apps like Alipay, WeChat or QQ to make an inquiry.

After registering with a phone number, users need to enter their name and ID number to know whether they were in close contact with someone infected.

Every registered phone number can be used to inquire for three ID numbers, Xinhua reported.

Those who have been in close contact are advised to stay at home and get in touch with local health authorities.

The app was developed by the General Office of the State Council, the National Health Commission and China Electronics Technology Group Corporations (CETC). The app received support from several government agencies including the National Health Commission, the Ministry of Transport, China Railway and the Civil Aviation Administration of China to ensure accurate, reliable and authoritative data.
