CHINA, A search for people from Wuhan is taking place on a national scale with the support of artificial intelligence and big data.
A man who had been to Wuhan, where a new outbreak of coronary pneumonia outbreaks, was surprised to see the police knocking on the door after he returned home, asked to check the temperature. The man, who was isolated in his own home in Nanjing, said he never told anyone about his trip to Wuhan. However, by reviewing the travel data, local authorities have identified and dispatched police to his home last week.
Despite the blockade since January 23, about 5 million people in many ways left Wuhan during the Chinese New Year. In an effort to stop the spread of nCoV, which has infected more than 34,000 people and left more than 724 dead, the Beijing government has used the familiar toolkit to find and control suspected cases: Statistics data and artificial intelligence.
A number of Chinese technology companies have developed apps that help people check whether they are traveling on the same flight or train with patients who have confirmed nCoV infection. This data is aggregated from a list published by the government.
In Beijing, a 2,400-unit apartment complex has formed a board tasked with checking flight and train data to create recent travel records of everyone in the area.
"Using big data technology to monitor and predict the spread of disease in real time," NHC National Health Committee said last week.
When Chinese authorities searched for suspected cases, they focused on whether the person had a fever because it was a common symptom of the new coronary pneumonia. While most relies on handheld thermometers, public transport zones are testing AI temperature sensing systems and infrared cameras.

A quarantine system developed by Baidu and Megvii is scanning travelers at railway stations in Beijing. Using face and infrared detection technology, the system automatically captures people walking within a distance of 5 meters. If anyone has a body temperature above 37.3 degrees Celsius, the system will display a warning. Baidu says the system can test more than 200 people per minute with an error of only 0.3 degrees Celsius, much faster than body temperature scanners at the airport.
In addition to measuring temperatures, Chinese technology firms are also developing a range of services to help control disease spread, such as the use of drones to distribute medical devices or map the path of a virus from Wuhan... In Guangzhou, robots are also deployed in many shopping centers to remind people who do not wear masks.
