Resource Overview

Role of Messaging in Risk Communication

Risk communication is the real-time exchange of information, advice, and opinions between experts or officials and people who face a threat to their survival, health, or economic or social well-being from a hazard (such as a zoonotic disease outbreak)[1]. Effective risk communication can manage people’s expectations during an emergency and assist response efforts by increasing efficiency and minimizing duplication or contradictory information.

As evidenced in the 2014-2015 West African Ebola outbreak, an effective response can depend on behavioral and social norm changes. These changes require robust, trustworthy communication and commitment to community engagement to support those affected by an outbreak to:

● Define the issue or problems affecting them.

● Reflect on the causes of the issues including how their behaviors impact them.

● Identify their ability to improve the issue.

● Organize themselves to address the issue.

Engaging communities prior to an event fosters trust and strengthens dynamic exchange between communities and health facilities that can accelerate community-led action in an emergency situation. Community engagement helps to ensure communities see the benefit in adopting the behaviors advocated in an emergency response and willingly cooperate with response teams.[2]

Coordinated, consistent messages are critical to providing an effective communication response, enabling multiple stakeholders to speak and engage the people they serve with one clear voice across all channels of communication.

Purpose of this Resource

The purpose of this document is to provide a synthesized, indexed reference of accurate, standardized COVID-19 information from the World Health Organization (WHO) and other trustworthy sources. This information is presented in simple, clear language to support the development of messages and materials needed for communication interventions.

As information is rapidly evolving, as the world learns more about COVID-19, it can be challenging to navigate and synthesize all the information presented online. This resource aims to facilitate easy access to recommendations from the WHO, the US Centers for Disease Control and Prevention (CDC), and other trusted sources to provide an easy way to check the technical accuracy of information and link directly to associated content on relevant websites to:

Support the sharing of consistent and credible information across numerous channels.

Inform activities and materials designed to raise awareness, promote healthy behaviors, and mobilize individuals, families and communities to take action to prevent the spread of COVID-19.

Provide a foundation of credible information to which more detailed and specific information can be added as it becomes available.

Provide a tool that can be easily adapted to individual country contexts to support coordinated response activities.

The primary intended audience of this resource includes program staff designing or implementing COVID-19 risk communication messages or community engagement activities. This could include staff from government ministries, departments, agencies, and supporting technical partners.

The ultimate intended audiences of the messages that may be developed based on this synthesized guidance include, but are not limited to, the public at large, employers, health care workers, schools, industries, and those working as a part of COVID-response.

The content in this document is directly referenced from WHO and CDC websites, as well as other trusted expert sources. It is presented along with source links and associated documents in alignment with the principles for effective message development for risk communication in the table below. This list, as well as additional tools and guidance to support the selection and adaptation of information in this guide for different contexts and audience needs, is provided in Part 6 of this document.

The organization of the document and how to navigate it are described below.

Using this Resource

It is recommended to consult this reference resource guide when designing communication tools, messages, and/or interventions for COVID-19. The information appropriate to your audience needs can be selected and content can be applied through a full spectrum of communication activities and channels as appropriate to your context and needs. Examples of these communication activities include but are not limited to:

  • Public announcements and press conferences/releases

  • Media communication (print, video, radio, and public awareness campaigns) and social media

  • Social mobilization and partner engagement

  • Interpersonal communication

  • Community engagement as appropriate.

Please note that not all information or messages are appropriate for every activity or channel of communication.

  • It is recommended to review the principles of effective messaging presented in Part 6 of this document before developing messages and materials with the content presented in the guide.

  • It is also recommended to identify your intended audience and understand their specific needs and barriers, as possible, before designing interventions or developing messages.

Understanding the behaviors, knowledge, aspirations, and feelings of an audience can help identify information needs to frame messages and activities that resonate and motivate behavior change. It also informs the selection of approaches and delivery channels to which audiences are more likely to respond for the desired changes to occur.

Your messages may need to be adapted for the intended audience, channel, or activity being designed depending on the context of when, where, and how the messages you develop will be used. Pre-testing of any materials is recommended, if possible (See Part 6)
