The KSA Ministry of Health recommends individual preventive measures such as use of face mask and disposable handkerchiefs and hand hygiene to mitigate the risk of RTIs. However, the efficacy of these measures against RTIs is debated [35] , and there have been no reliable controlled studies investigating their efficacy on the incidence of Hajj-related RTIs. The use of face masks may not provide optimal protection from infection, but that may reduce the spread of smallsized saliva droplets around when coughing or sneezing which is the main mode of transmission of most RTIs. Mandatory use of face mask in public places is considered one of the effective measures in controlling the COVID-19 pandemic [54] [55] [56] , but no investigation has been conducted in the context of MGs so far.	./cache/cord-339124-m7choyr6.txt	./txt/cord-339124-m7choyr6.txt
