Social networks Amazon, Google, Microsoft and Facebook held a meeting in London to discuss how they can play role in the coronavirus crisis.                                  

They discussed modeling and tracking of data that may help prevent the virus.   

Facebook is already working with researchers at Harvard University and National Tsing Hua University, Taiwan sharing data about people's movements and high-resolution population density maps, which helps them foresee the spread of virus.             

Meanwhile, to help people who want to track their own health Google is developing a small body-worn temperature patch that transmits data to a phone app. 

Earlier, a World Health Organization report said Artificial Intelligence and big data were a key part of China's response to the virus.
