systems, reduce risk perception, discourage healthy behaviors and contribute to vaccine hesitancy. This can be prevented.

“Mistrust is the outgrowth of
the perception that promises
were broken and values were
violated.”
--Dr. Barbara Reynolds
former senior communications and crisis
advisor at the US Centers for Disease Control
and Prevention (CDC)

12. Why is addressing our current information
environment so difficult in public health?
Diminished public trust in
officials, coupled with
increasing diversity of
online platforms, creates
a context vulnerable to
the spread of
misinformation.
Over the past 15 years, narratives that influence knowledge, attitudes,
perceptions, and behaviors related to public health emergencies have
circulated faster in our increasingly digitized society. To keep pace,
health authorities must be quicker to identify and respond to circulating
narratives.
Debunking misinformation will have
limited effectiveness unless the larger
social and cultural forces that bolster
misinformation are addressed, which
requires evidence-based approaches that
leverage socio-behavioral and
epidemiological insights.
Excerptedfrom the US National Academy of Sciences, Engineering and Medicine Workshop on Navigating Infodemics and Building Trust during Public Health Emergencies, April 2023
