Since COVID-19 emerged, a plethora of misinformation has undermined the public's ability to identify reliable sources of accurate information. To identify the range of methods governments used to address COVID-19 misinformation, we conducted a content analysis of international media and evaluated government actions in light of international law, which protects freedom of expression and calls on governments to guarantee this fundamental right even during a pandemic or other emergency. We identified five categories of government activities: (1) disseminating and increasing access to accurate information, (2) restricting access to accurate information, (3) disseminating disinformation, false information, and misinformation, (4) addressing commercial fraud, and (5) criminalizing expression. The goal of addressing COVID-19 misinformation is best served by protecting expression, disseminating factual information, ensuring strong protections for whistleblowers, and supporting an independent media environment. Conversely, governments undermine public health when they create a state of uncertainty and violate human rights.
