The disinformation of the population - which is more successful in Germany than in Italy - is fuelled by social media. But here is a useful contribution from YouTube:
According to its own information, YouTube has deleted more than 1 million (!) videos with false information about the Corona virus since February 2020; the films concerned both false cures and false reports in general. YouTube follows the guidelines of the US Department of Health and the World Health Organisation (WHO).
In Germany, for example, the misconception is widespread that a deworming agent for horses (ivermectin) helps against C 19. According to a report in the BZ (Berliner Zeitung, internet portal of 7 November 2021), a mother of two in Berlin is said to have already died from it.
