Roughly one in three people across the United States, Spain, Germany, United Kingdom, Argentina and South Korea say they've seen false or misleading information on social media linked to the coronavirus, according to a new report.

The analysis, published Wednesday by the Reuters Institute for the Study of Journalism at the University of Oxford, comes as Facebook and Google say they've pulled out all the stops to clamp down on how misinformation about Covid-19 is shared on their networks. Tech giants continue to face accusations that they're not doing enough to remove online falsehoods and other digital content that may put people's lives at risk.


These efforts to crack down have yet to eliminate all such material from social media, according to the Oxford University academics who polled more than 8,500 people, collectively, across the six countries during the final week of March and first days of April.
