Twitter will now warn users when tweets contain disputed or misleading information about COVID-19.
The social media giant made the announcement on Monday as part of a new approach to misinformation that will eventually extend to topics beyond the coronavirus.
The new labels will provide links to more information in cases where the risk of harm from the tweet is not severe enough to be removed but where people could be confused or misled.
While other tweets may contain warnings that say the information conflicts with guidance from public health experts before a user views it.
Twitter said these labels will also apply to tweets that have been sent before its announcement and will be used regardless of who sent the tweet.
This comes as social media companies, such as Facebook, are under pressure to combat misinformation about COVID-19 that has spread on their platforms.
These range from bogus cures to misinformation linking the virus with conspiracy theories about high-profile figures.
