Mass gathering in Qatar 2022 World Cup. What should be especially monitored?

At the end of 2022, the football world championship will be held in Qatar. These types of meetings require a risk analysis. It proposes an approach to determine which health risks should be prioritized. We use a mixed methodology (Hierarchical Process Analysis, World Health Organization STAR and European Commission INFORM) to determine the risk level of a total of 12 health entities. Our analysis identifies 6 health entities with a moderate risk. There are 4 whose valuation is as low risk and 2 as very low. In our work we focus the analysis from a point of view of the route of transmission or presentation of health events, which facilitates a visualization of the preventive measures to be implemented, both organizationally and individually by the attendees.
