Abstract
The Hajj pilgrimage, held in the Kingdom of Saudi Arabia, is among the largest mass gatherings in the world. More than 2.5 million Muslim pilgrims assemble from over 180 countries worldwide to perform Hajj. The Saudi government recognized the potential risks associated with this event since the first novel coronavirus disease 2019 (COVID-19) case was detected in the country on March 2, 2020. The return of possibly infected pilgrims to their countries after this huge mass gathering event could have turned Hajj into a superspreading event during the global COVID-19 pandemic. A multidisciplinary Saudi team from governmental sectors, including the Global Center for Mass Gatherings Medicine, shared in the assessment, planning, execution, and success of this holy event to prevent the spread of disease. The World Health Organization welcomed the Saudi government's decision to protect the wellbeing and safety of pilgrims and strengthen regional and global health security. A total of 1,000 pilgrims from 160 different countries were randomly selected to perform the rituals. Of all the pilgrims, healthcare personnel, and nonmedical employees facilitating the rituals, no confirmed cases of COVID-19 were identified during or after Hajj. This article highlights the success of the risk mitigation plan in place during the Hajj pilgrimage in 2020 (1441 Hijri year) during the COVID-19 pandemic and the efforts of the Saudi government to prevent associated outbreaks.
