Health Education in Mass Gatherings: A Scoping Review to Guide Public Health Preparedness and Practice[1]

Zaini S, et al · 2025 · Healthcare (Basel)

Summary

Scoping review of 17 studies of health-education interventions delivered to mass-gathering attendees (dominated by Hajj/Umrah pilgrim education). Effective interventions shared three design features: delivery beginning in the ORIGIN COUNTRY before travel and continuing through the event; tailoring to the specific event's hazard profile; and delivery in attendees' local languages. Ad-hoc, on-site-only, single-language education performed poorly. Calls for standardized outcome measures for education interventions.

So what

The evidence spine for the prevention side of event medicine — the layer that acts before anyone reaches the medical tent. The origin-country + event-long + local-language triad is directly actionable doctrine for MGMI's pilgrimage and risk-communication pages, and it dovetails with Delgado (risk-communication effectiveness unevaluated) and Takeda (advisories not issued): the field knows how to educate but rarely measures or even deploys it.

Key findings

  • 17-study scoping review of attendee health education at mass gatherings
  • Effective design triad: origin-country start, event-long continuation, local language
  • Tailoring to the event hazard profile distinguishes effective programs
  • On-site-only, single-language education underperforms
  • Calls for standardized outcome measures; free PMC
