The document “Guidance on Law and Public Health Emergency Preparedness and Response” provides recommendations for governments on how laws and policies can support effective preparation for and response to public health emergencies such as epidemics or pandemics. It explains the role of legal frameworks in enabling governments and institutions to prevent, detect and manage health crises while protecting human rights and supporting coordinated action across sectors. The guidance highlights lessons learned from the COVID-19 pandemic and examines how national laws, policies and emergency powers were used in many countries. It also identifies common gaps in legal preparedness and proposes key elements that should be included in national legislation, such as clear roles and responsibilities, early warning systems, protection of vulnerable groups and cooperation with humanitarian actors. Overall, the document serves as a practical tool to help countries review and strengthen their legal and policy frameworks for managing public health emergencies.
