Journalists have been confronted with a “tsunami” of Covid-19 disinformation since the start of the pandemic including a concerning amount from governments and state officials, according to a new study.

Of the 1,406 journalists who participated in the global survey from the International Centre for Journalists and Tow Center for Digital Journalism at Columbia University, 28% said they were encountering disinformation connected to the coronavirus many times a day.

Some 35% saw it many times a week and 18% weekly – meaning 81% were seeing it at least once a week.
