What inaccurate statement did Donald Trump make regarding mask usage?

The claim that 85% of mask wearers get COVID-19 is inaccurate because it significantly misrepresents the effectiveness of masks in reducing transmission of the virus. Public health studies indicate that masks are a crucial tool in mitigating the spread of COVID-19 by filtering respiratory droplets that may contain the virus. The assertion that such a high percentage of mask wearers contract the virus not only discourages their use but also undermines the public's understanding of the protective measures available during a pandemic.

Understanding mask efficacy is central to public health messaging, which is aimed at reducing fear and encouraging collective action to prevent the spread of COVID-19. Therefore, any statements suggesting that a vast majority of mask wearers have contracted the virus can lead to confusion and resistance against proven safety practices.
