Risk Perceptions during COVID-19 Pandemic: Applying Knowledge on Public Compliance to Protective Measures during SARS to Understand Risk Communication

Abstract

The outbreak of COVID-19 in 2020 has caused significant environmental and economic loss across the globe. The government’s promotion of non-pharmaceutical treatment such as social distancing, hand washing, and mask-wearing can be equally important in disease control compared to the conventional use of pharmaceutical treatment. Risk perception is often used as an important mechanism to understand an individual's compliance with these protective measures. The present article examines the application of previous knowledge about public risk perception, decision making, and behavioral change to the current global pandemic and evaluates the most effective way of governmental messaging. The article analyzes empirical research conducted during COVID-19 across the globe where risk perception is found to be a strong determinant of people’s adoption of public health behavior. Demographic factors can significantly alter people’s understanding of risk due to the variation of individualistic view and prosociality of each nation. Cognitive biases can also affect people’s efficacy beliefs and confidence levels in government which can shape their risk perception to a great extent as well. Combining studies on both SARS and COVID-19, we are able to employ past knowledge to draw conclusions on risk communication and governmental promotion of protective measures during the current global pandemic.
