Public health considerations for mass gatherings in the Middle East and North Africa (MENA) region.

This review describes major mass gatherings in the MENA region and the public health implications of these events, and provides recommendations for public health officials of the host country. Through our search of the literature for peer-reviewed publications, we identified relevant 77 papers; all were related to the annual Hajj. Using the information obtained from the literature review, the Eastern Mediterranean Public Health Network (EMPHNET) and the Centers for Disease Control and Prevention (CDC) developed and conducted 2 workshops on Public Health Surveillance during Mass Gatherings for field epidemiology training programmes and ministry of health focal points from 10 countries. The main potential public health concerns associated with mass gatherings include: infectious diseases (e.g. respiratory disease, gastro-intestinal tract disease, foodborne disease), injuries, traffic accidents, heat-related illnesses, insect stings, non-communicable diseases and terrorism.
