A wide range of natural and man-made hazards increases the health risks at mass gatherings (MGs). Building on the Sendai Framework for Disaster Risk Reduction 2015-2030, the World Health Organization (WHO) developed the Health Emergency and Disaster Risk Management (H-EDRM) framework to strengthen preparedness, response, and recovery from health emergencies in the communities and emergency-prone settings, such as MGs. The Jeddah tool is derived from the H-EDRM framework as an all-hazard MG risk assessment tool, which provides a benchmark for monitoring progress made in capacity strengthening over a given period for recurrent MGs. Additionally, it introduces a reputational risk assessment domain to complement vulnerability and capacity assessment matrixes. This paper describes the key elements of the Jeddah tool to improve the understanding of health risk assessment at MGs in the overarching contexts of health emergencies and disaster risk reduction, in line with international goals.
