    Evidence for transmission of SARS-CoV-2 at religious mass gatherings: A systematic review
    (Elsevier, 2024-06-12) Goumballa, Ndiaw; Hoang, Van Thuan; Al-Tawfiq, Jaffar A.; Sokhna, Cheikh; Gautret, Philippe; Medicine, School of Medicine
    Background: Transmission of SARS-CoV-2 at major mass gatherings (MGs) has been observed during the COVID-19 pandemic. Methods: In this systematic review done according to the PRISMA guidelines, PubMed and Scopus databases were searched for relevant studies to describe the epidemiology of SARS-CoV-2 in relation to major religious MGs including the Grand Magal of Touba (GMT), Hajj, Umrah, Kumbh Mela, Arbaeen and Lourdes pilgrimage during the COVID-19 pandemic. Results: Ten articles met the inclusion criteria and were included.No cases of SARS-CoV-2 were detected at 2020 and 2021 GMT or at the 2020 Hajj. In a small study, 7 % of tested individuals were positive after the 2022 GMT. SARS-CoV-2 prevalence during the 2021-2022 Hajj and Umrah seasons varied from 0 to 15 % in different studies. At the 2021 Kumbh Mela, 0.4 million COVID-19 cases were diagnosed among returning pilgrims across India and 1 % tested positive during a one-day survey conducted on participants. During the 2021 Arbaeen pilgrimage, 3 % pilgrims were tested positive. No relevant data were found in relation to SARS-CoV-2 transmission at the 2021 Arbaeen and Lourdes pilgrimages. Conclusion: The transmission of the SARS-CoV-2 virus during religious MG events depends on many factors such as: the number and density of pilgrims, the intensity of circulation of the virus in the hosting country and in countries sending international participants at the time of the event, the transmissibility of virus variants at the time of the event, the various preventive measures adopted, and the immune status of the pilgrims.

    The Tokyo Olympic Games and the Risk of COVID-19
    (Springer Nature, 2020-10-30) Hoang, Van Thuan; Al-Tawfiq, Jaffar A.; Gautret, Philippe; Medicine, School of Medicine
    Purpose of review: We reviewed the occurrence of outbreaks at past Olympics and discuss the threat of the COVID-19 pandemic at the Tokyo Games. Recent findings: Evidence for large respiratory tract infection outbreaks at past Olympics is scant. Nevertheless, in order to control the spread of the COVID-19 outbreak, the Tokyo 2020 Olympics were postponed for 2021. Given the high contagiousness of the disease and the epidemiology of COVID-19 in Japan, this decision was appropriate and important in order to safeguard athletes and the public. However, it is a major problem for Japan, involving massive financial losses and a lost opportunity for athletes, coaches, and instructors. Summary: Up-to-date epidemiological data is needed on which to base an appropriate decision regarding the Tokyo 2021 Olympics. The actual effect of cancellations of such events in reducing the spread of COVID-19 needs to be determined.
