Table 3.

Practical suggestions provided by the World Health Organization to prevent and control infection during mass gatherings.1.

Before the event
  • Identify infection risk

  • Identify infection prevention and control (IPC) measures already in place

  • Determine the training status of HCPs on IPC measures and address any shortcomings

  • Examine existing legal framework for implementing appropriate IPC measures

  • Perform cost-effectiveness analysis of IPC measures

  • Assess status of public health service and other services involved in IPC

  • International collaboration to assist risk assessment, share information and experience, and ensure rapid communication and alert about potential threats and access to expertise, laboratory tests, etc.

  • Assess the potential for mitigation measures, including pre-event immunization, assessment of health status before entry, setting up sanitation stations, etc.

  • Assess the impact of more restrictive IPC measures on public opinion, political, economic, psychological consequences, and human rights

  • Develop IPC guidelines according to international recommendations and adapt these to the local situation

  • Train staff involved in events in IPC measures, e.g.,, point of entry staff, security, first aid, environmental health staff responsible for hygiene, HCPs (in hospitals, emergency departments)

  • Regularly check supplies of equipment and utilities to be used in IPC (vaccines, antimicrobials, disinfectants, etc.), to ensure there are sufficient, easily accessible quantities

During the event
  • Ideally, provide free access to healthcare to encourage rapid identification and response to potential infection

  • Provide easily accessible written information to all participants in the languages used by most attendees, taking into account health beliefs and practices and the social context. Populations with low health literacy need to be supported and empowered to act on health information, for example, using visual aids

  • Immunize contacts of infected individuals and monitor the health condition of close contacts

  • Transport cases according to established protocol

  • Isolate individuals suspected to be contagious and quarantine those who have been exposed to communicable disease

  • Provide appropriate responses to infection risk, e.g. easy access to hand hygiene measures, wearing of face masks, encouragement of good cough etiquette, social distancing, and contact avoidance

  • Communicate infection risk with general public, using materials developed before the event

After the event
  • Ongoing situational awareness to ensure any information linked to the spread of communicable diseases is reported rapidly and appropriate response is undertaken. This may involve the international community for a large mass gathering

  • International collaboration after the event, including the exchange of knowledge and experience
