AI technology, big data and 5G are playing bigger roles in the nationwide novel coronavirus control to help identify cases and also develop vaccines and treatment. The examples of how high-tech is changing the development of the battle with the virus are fascinating.

A sensor system to monitor the development of patients in critical condition using big data is 10 to 100 times faster than a traditional system in indexing and searching for data. The system is used in screening patients in critical condition as well as suspected cases.

Data from the nation's three telecommunication providers and the Baidu map application provides the number of people who migrated from the virus epicenter of Hubei province and where they traveled, to help guide control measures in different regions.

Full 5G coverage in the two makeshift hospitals of Huoshenshan and Leishenshan has ensured smooth and reliable communications and will also play a critical role in intelligent medical treatment.

Under the 5G network in the ward, robots and cloud medical consultation systems can help avoid unnecessary contact between medics and patients to reduce cross infection.

In public disease control, a no-contact infrared sensor system to identify passersby with a fever or without masks has been widely used in airports, subways and highways. Remote medical consultation can help other patients who are not advised to go to the hospital. AI doctors have been introduced in hospitals and residential communities to help screen suspected cases and diagnose symptoms.

People don't have to fill in personal information over and over if they present a green health QR code when commuting in public. People in more than 100 cities will get their own codes that they had previously applied for online after scanning the verification codes through Alipay.
