In a One Health emergency, which of the following best describes risk communication best practices?

• A. Centralized, unilateral messaging with no feedback.
• B. Transparent, timely, culturally appropriate messaging; trusted spokespeople across sectors; two-way communication and feedback loops.
• C. Delayed communication until all data are validated, with limited sector involvement.
• D. Messaging only through social media without community engagement.

Answer: (B)

In risk communication during a One Health emergency, the best practice is to provide transparent, timely, and culturally appropriate messaging delivered by trusted spokespeople across sectors, with two-way communication and feedback loops. This approach matters because it builds trust and legitimacy when information comes from credible voices in human, animal, and environmental health, and it acknowledges that communities have diverse needs, languages, and cultural contexts. Timeliness matters to reduce uncertainty and enable rapid protective actions, while cultural appropriateness ensures messages are understood and acted upon. Two-way communication and feedback loops keep the information current, allow communities to voice concerns, report observations, and help detect misinformation, so messaging and responses can be adjusted as the situation evolves.

Other approaches fall short because they rely on centralized, unilateral messaging with no feedback, which erodes trust and misses local perspectives; delay communication until all data are validated, which can leave people uninformed during critical moments; involve only a single sector, weakening coordination and credibility; or push messaging solely through social media without community engagement, excluding those without online access and eliminating opportunities for dialogue.
