In an effort to get ahead of the corona virus, China is turning to big data and artificial intelligence to help identify those infected.

According to the International Business Times (IBT), “several Chinese tech firms have developed apps to help people check if they have taken the same flight or train as confirmed virus patients, scraping data from lists published by state media.” The data is also giving officials the ability to track down individuals who may have been exposed, screen them and forecast how the disease will spread.

Baidu developed a system that uses infrared and AI-powered facial recognition to screen people at the railway station for a possible fever. Anyone with a temperature 99 degrees Fahrenheit or above is flagged for further checks. IBT reports that the “system can check more than 200 people a minute, far faster than the thermal scanners used at airports.”

Companies are also developing ways to both prevent the spread of the disease, as well as help those already infected. Some cities are using robots to scold people who are not wearing masks in public, while other companies are working on using drones to deliver medical supplies to the sick.

As China continues to struggle with the deadly outbreak, technology may well be the key to turning the tide.
