COVID-19 misinformation refers to misinformation and conspiracy theories about the scale of the COVID-19 pandemic and the origin, prevention, diagnosis, and treatment of the disease COVID-19, which is caused by the virus SARS-CoV-2. False information, including intentional disinformation, has been spread through social media, text messaging, and mass media. False information has been propagated by celebrities, politicians, and other prominent public figures. Many countries have passed laws against "fake news," and thousands of people have been arrested for spreading COVID-19 misinformation. The spread of COVID-19 misinformation by governments has also been significant.
