Catastrophic Risk: Waking Up to the Reality of a Pandemic?

Area of Science:

• Public Health
• Risk Perception
• Behavioral Economics

Background:

• Assessing public perception of catastrophic pandemic risk is crucial for effective public health preparedness.
• The 2014 West African Ebola Outbreak served as a significant global health event, potentially influencing public awareness and concern.
• Understanding how major events impact risk perception is key to informing policy and resource allocation.

Purpose of the Study:

• To investigate whether the 2014 West African Ebola Outbreak altered US citizens' perception of catastrophic pandemic risk.
• To compare public priorities for pandemic preparedness spending against other risks like environmental disasters and terrorism.
• To examine the influence of the availability heuristic on risk perception following a salient public health event.

Main Methods:

• A natural experiment design was employed, surveying US citizens before and after the 2014 Ebola Outbreak.
• Public spending priorities for different risk scenarios (pandemic, environmental, terrorism) were assessed.
• Analysis focused on changes in risk perception and prioritization in response to the Ebola event.

Main Results:

• US citizens demonstrated complacency towards pandemic risk prior to the Ebola outbreak.
• The Ebola outbreak did not significantly increase the perceived threat or priority of pandemic preparedness spending.
• Pandemic risk continued to be valued less than environmental or terrorism risks, contrary to expectations based on the availability heuristic.

Conclusions:

• Major public health crises like the Ebola outbreak may not be sufficient to significantly shift public perception of long-term pandemic risk.
• Public awareness and concern for pandemic preparedness remain relatively low compared to other perceived threats.
• Future public health strategies should consider factors beyond immediate events to effectively communicate and prioritize pandemic risks.
