Hajj 2021: Role of mitigation measures for health security.

PURPOSE: After the impressive results of the 2020 Hajj management, Saudi authorities decided to expand the quota to 60,000 pilgrims in 2021, which resulted in a convenient and successful experience. PATIENTS AND METHODS: This was a retrospective pre and post-study study conducted on all pilgrims attending the 2021 Hajj using the polymerase chain reaction (PCR) test surveillance with paired-swab samples (pre-Hajj and post-Hajj) to evaluate the risk potential of COVID-19 among Hajj pilgrims, the effectiveness of preventive measures and the potential effect of the Hajj ritual as a huge mass gathering on the epidemiological situation of the Saudi Arabian population. RESULT: Forty-one cases had positive COVID-19 infections out of a total of 58,428 pilgrims who attended the 2021 Hajj season, as detected by nonmandatory pre- and post-Hajj PCR. Notably, the 2021 Hajj season achieved a decreasing leg of the COVID-19 pandemic curve. The adjusted incidence rate in KSA from July 11th to August 7th ranged from 19 to 24 cases per 100,000 population. In contrast, the incidence rate for the same duration in Hajj ranged from 3 to 7 cases per 100,000 pilgrims. CONCLUSION: The Saudi mitigation plan ensured the safety of pilgrims and healthcare workers for Hajj, successfully limited the risk of COVID-19 transmission inside and contributed to global health security. The success story of Hajj in 2020 and 2021 during the pandemic represents a successful model for planning, achieving and managing future mass gatherings by integrating technology with global and national health policies and public health measures.

COVID-19 Mitigation Plans During Hajj 2020: A Success Story of Zero Cases.

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.
