Risk communication is the real-time exchange of information, advice and opinions between experts or officials and people who face a hazard or threat to their survival, health, or economic or social wellbeing. The purpose of risk communication is to enable people at risk to make informed decisions to mitigate the effects of a threat (hazard) – such as a disease outbreak – and take protective and preventive measures. Risk communication is proven to be a critical tool in emergency preparedness and response. It is a core capacity of the International Health Regulations (IHR 2005) and is one of five strategies within the Pandemic Influenza Preparedness (PIP) framework. 

Community engagement is the process of developing relationships and structures that engage communities as equal partners in the creation of emergency response solutions that are acceptable and workable for those they impact. The goal of community engagement is to empower communities to confidently share the leadership, planning and implementation of initiatives throughout the health emergency response cycle. 

Lessons learned in risk communication and community engagement initiatives in every public health emergency have informed subsequent response efforts, leading to planning that better integrates risk communication into operational activities and brings communities to the forefront as valued and essential partners for effective, equitable and inclusive emergency preparedness and response. Risk communication and community engagement works alongside other technical areas to ensure that accurate information is delivered to communities in ways that are acceptable and workable for them.
