The ongoing coronavirus disease 2019 (COVID-19) outbreak is a Public Health Emergency of International Concern (PHEIC), and the emergence of new epicentres of spread, such as South Korea and Iran, besides Wuhan, China, should draw attention to potential superspreader events.1 Of concern is the continuous Umrah pilgrimage to Saudi Arabia by Muslim pilgrims from more than 180 countries. In addition to the non-pilgrim air traffic (39 million people in 2018), Saudi Arabia received 7·5 million Umrah visa holders in 2019 (appendix).
