Facebook said Thursday it will begin alerting users if they have interacted with harmful “misinformation” about the coronavirus, part of new, aggressive steps to combat what health authorities have described as a global “infodemic.”

The messages — which will appear in users’ News Feeds — will direct people to official, credible information from the World Health Organization in an attempt to ensure that dangerous myths about the disease, its origins and how it is treated don’t continue to proliferate, either on the social networking site or in the real world.
