This article provides five risk perception domains to address when communicating with the public about COVID-19.

Using real-time qualitative data collection and analysis, researchers analyzed social media posts and emails to assess COVID-19 risk perception and trust towards public authorities and to inform weekly risk communication efforts. Based on the results, meaningful communication should be created around five risk perception domains:

Catastrophic potential

• Provide facts
• Express care and concern
• Avoid downplaying strong feelings

Probability of dying

• Emphasize known facts about COVID-19 mortality
• Emphasize actions taken by authorities

Reasons for exposure

• Emphasize known facts about the global situation to address the mode of transmission
• Provide effective prevention efforts to address the location of transmission
• Humanize infected people by telling their stories

Belief of being in control of the situation

• Emphasize controllable actions (e.g., handwashing, cough etiquette)

Trust towards authorities

• Repeat information and provide an explanation
• Communicate actions
