Objectives: Outbreak reports are essential for documenting the spread of and responses to disease outbreaks. However, there is a lack of standardized reporting guidelines that encompass broader perspectives on outbreaks. We aimed to develop a universal reporting guideline applicable to diverse outbreak reports and community epidemic interventions, the “Guidelines for Community Outbreak Investigation Reporting (G-CORE).”

Methods: G-CORE is designed to address the challenges in documenting various outbreak scenarios, including infectious diseases and non-infectious environmental hazards. The development of G-CORE involved a structured process, including a comprehensive literature review of recent outbreak reports from leading journals and an analysis of existing reporting guidelines. The process also involved project registration with the EQUATOR Network and collaboration with experts in various fields. Following the initial drafting, an internal (team) review was conducted to evaluate the guidelines' robustness and relevance. Subsequently, the guidelines underwent revision based on feedback from external experts and potential users, including authors with experience in outbreak reporting. The project also includes plans for widespread dissemination and periodic revisions to adapt to developments and user feedback.

Results: G-CORE will provide a structured framework for reporting outbreak investigations, comprising a detailed checklist and Explanation & Elaboration documents.

Conclusion: G-CORE establishes a new standard in outbreak reporting, facilitating comprehensive, clear, and actionable public health communications. Its development marks a significant advance in the documentation and management of public health outbreaks.
