TL;DR

This study analyzed health issues and healthcare use among Hajj 2024 pilgrims to improve future health service planning during the pilgrimage.

Contribution

The study provides a detailed analysis of disease burden and healthcare utilization patterns specific to Hajj 2024.

Findings

Upper respiratory tract infections were the most common diagnosis among pilgrims.

Healthcare utilization varied by location, with Mena having the highest primary care visits.

Older pilgrims and those with chronic conditions required targeted interventions.

Abstract

Background: The Hajj pilgrimage is one of the largest annual mass gatherings in the world, and it presents unique healthcare issues due to the vast number and diversity of participants. Optimizing the delivery and planning of health services requires an understanding of prevalent diseases and healthcare usage patterns. The aim of the study was to examine the patterns of disease burden and healthcare utilization among 2024 Hajj pilgrims.

Methods: This study used a retrospective, descriptive cross‑sectional design. Data from 37,758 adult patient records in the outpatient clinics (OPCs) of the primary healthcare centers (PHCs) and hospitals located at the holy sites (Mena, Arafat, and Muzdalifah) during Hajj 2024 were analyzed. Data covered demographics, nationality, diagnoses, discharge outcomes, and healthcare utilization in holy sites. Patterns and associations were assessed using descriptive statistics and chi‑square testing (p < 0.05).

Results: Most pilgrims were men (65.5%), and older than 60 years of age (26.4%). They came from more than 100 different countries. The most frequent diagnosis (44.6%) was upper respiratory tract infections (URTIs), which was followed by dermatitis (6.3%), gastrointestinal disorders (7.4%), headaches (7.8%), and musculoskeletal problems (7.3%). Geographically, disease prevalence varied: URTIs were most common in Mena (46.3%), dermatitis peaked in Muzdalifah (14.8%), and heat exhaustion was most common in Arafat (9.4%). Primary care use peaked in Mena (14,500 visits), mirroring pilgrim mobility.

Conclusion: The results emphasize the necessity for flexible, data‑driven resource allocation by highlighting the dynamic and site‑specific character of healthcare demands during the Hajj. To improve health outcomes in upcoming Hajj seasons, it is imperative to enhance infection control, heat illness prevention, and culturally competent care, in addition to tailored interventions for older pilgrims and those with chronic illnesses.
