China turns to AI, data in fight against virus

Beijing: A man who had travelled to Wuhan — the central city at the heart of China’s coronavirus crisis — was surprised when police showed up at his door after he returned home, asking to check his temperature. The man, who had quarantined himself at home in Nanjing, eastern Jiangsu province, said he had not told anyone about his recent trip to the city.

But by trawling through travel data from Wuhan, local authorities were able to identify him and dispatch officers to his home last week, according to a newspaper article posted by the Nanjing government.

As Chinese authorities race to contain the spread of a new virus, which has infected more than 34,000 people and killed more than 700 in China, Beijing is turning to a familiar set of tools to find and prevent potential infections: data tracking and artificial intelligence.
