Umrah is a spiritual practice that is not obligatory and has no fixed date or time to be performed so may be seasonally affected [3]. Similarly to the Hajj and other mass gatherings, the Umrah entails global movement of people, gathering of crowds, and therefore an increased health challenge, including the risk of spreading infection [4]. Respiratory tract infections, overcrowding accidents, pollution, and many other medical and health issues are encountered by the host country, which requires special attention and measurable responses to mitigate these risks [4,5]. Without proper planning and preventative measures, this religious activity can overwhelm the health system of the host country and impact global health preparedness, because the majority of Umrah pilgrims come from, and return to, their different countries [5,6].
