Participants completed a structured questionnaire and provided combined nasopharyngeal and oropharyngeal swab specimens for multiplex real-time RT-PCR detection of common respiratory viruses.

The prevalence of viral detection was 6.7% pre-Hajj, 16.0% during Hajj and 21.4% post-Hajj. Influenza A was the predominant virus (34.5%), followed by rhinovirus (24.1%), SARS-CoV-2 (20.7%), respiratory syncytial virus (13.8%), adenovirus (5.2%), and seasonal human coronaviruses (1.7%). Diabetes mellitus, chronic lung disease and smoking were independently associated with increased odds of respiratory virus detection.
