SAN FRANCISCO: Facebook Inc said on March 6 it would start surveying some US users about their health as part of a Carnegie Mellon University research project aimed at generating "heat maps" of self-reported coronavirus infections.
The social media giant will display a link at the top of users' News Feeds directing them to the survey, which the researchers say will help them predict where medical resources are needed. Facebook said it may make surveys available to users in other countries too, if the approach is successful.
