Instagram is embracing its potential as a news source, employing its ubiquity to distribute Coronavirus prevention techniques through a new call-out at the top of its homescreen feed. In some countries, Instagram will show a link to information from the World Health Organization and local health ministries along with a message like this: “Help Prevent the Spread of Coronavirus: See the latest information from the World Health Organization so you can help prevent the spread of COVID-19. — Go to who.int”

An Instagram spokesperson tells TechCrunch that the notice will start appearing in countries that have seen significant impact from the virus.
