Twitter on Monday announced it will begin to add warning messages and labels to tweets spreading disputed or misleading information about COVID-19. The labels will direct users reading these tweets to a Twitter-curated page or to external resources that offer additional information and context about the claims being made in the tweet. The warnings, meanwhile, will cover the tweet — requiring an extra click to view the content.

According to the screenshots Twitter published, tweets sharing potentially harmful, misleading information will be labeled with a link that reads “Get the facts about COVID-19.” This link will be preceded by an icon of an exclamation mark in a circle in order to draw the user’s attention.
