Urgent Warning: Evidence-Based Concerns Regarding Mass Gathering Events During Arbaeen in Hazardous Weather Conditions.

The Arbaeen ceremony is the largest annual mass gathering in the world, attracting millions of Muslim pilgrims each year. However, the event takes place during the summer in Iraq, coinciding with extreme heat and dust storms. Climate change hazards, such as heat waves and dust storms, can have destructive effects on human health, leading to increased mortality and the spread of various diseases. This manuscript recommends measures to stakeholders in emergency or public health management to develop a preventive plan for the Arbaeen ceremony. These measures include improving planning and risk assessment, enhancing capacities, reducing vulnerabilities, increasing knowledge and awareness among pilgrims, developing communication and support systems, ensuring compliance with safety protocols, and regularly assessing evacuation routes. Implementing these measures will contribute to ensuring the safety and well-being of participants during the Arbaeen ceremony in the years ahead.
