In this systematic literature review, the World Health Organization synthesized evidence for the development of emergency risk communication guidelines.

Political goodwill, leadership, and centralized health systems are considered key factors in planning and policy-making for emergency risk communication. Factors related to the integration of emergency risk communication for public health emergency preparedness include nullifying restrictions that hinder the timely release of information, including amending laws and regulations where feasible; modifying organizational factors; and renovating leadership structures if needed. Key elements to enhance information sharing include the creation of interdisciplinary taskforces, engagement of local stakeholders, and tailoring information systems to be most functional. Emergency risk communication should follow WHO guidelines, be transparent, timely, and based on scientific evidence.
