The dissemination of information via social media is important, particularly during a public health emergency. However, while it is undoubtedly useful in the targeting of genuine health communications, social media may also be used to spread health-related misinformation at times of disease outbreak or pandemic. The study presented here researches the spread of COVID-19 misinformation in Saudi Arabia, by exploring the relevant understanding, attitudes, and behaviors of Saudi Arabian citizens. The current study comprises a survey of 318 adults in Saudi Arabia, of all age groups and educational backgrounds, and from all Saudi Arabian provinces. This study highlights the significance of COVID-19 misinformation and concludes that, despite risks to public health and wellbeing, Saudi Arabian citizens do not consider COVID-19 misinformation to be a significant problem. Participants in this study were relatively aware of such misinformation and its dangers, but it did not greatly concern them, and generally they declined to tackle it proactively.
