Following the report of a non-travel-associated cluster of monkeypox cases by the United Kingdom in May 2022, 41 countries across the WHO European Region have reported 21,098 cases and two deaths by 23 August 2022. Nowcasting suggests a plateauing in case notifications. Most cases (97%) are MSM, with atypical rash-illness presentation. Spread is mainly through close contact during sexual activities. Few cases are reported among women and children. Targeted interventions of at-risk groups are needed to stop further transmission.
Introduction. EURO2020 generated a growing media and population interest across the month period, that peaked with large spontaneous celebrations across the country upon winning the tournament. Methods. We retrospectively analysed data from the national surveillance system (indicatorbased) and from event-based surveillance to assess how the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) changed in June-July 2021 and to describe cases and clusters linked with EURO2020. Results. Widespread increases in transmission and case numbers, mainly among younger males, were documented in Italy, none were linked with stadium attendance. Vaccination coverage against SARS-CoV-2 was longer among cases linked to EURO2020 than among the general population. Conclusions. Transmission increased across the country, mainly due to gatherings outside the stadium, where, conversely, strict infection control measures were enforced. These informal 'side' gatherings were dispersed across the entire country and difficult to control. Targeted communication and control strategies to limit the impact of informal gatherings occurring outside official sites of mass gathering events should be further developed.
Issue/Problem
Religious Mass Gathering (MG) represent one of public health challenges for Health Authorities due to potential spread of communicable diseases. This is much more true during a pandemic as COVID-19. Surveillance is crucial to prevent further spreading of infectious disease related to a religious MG.
Description of the problem
During international contact tracing activities an increase of reporting of COVID-cases with a travel history to a Catholic shrine in Europe was observed, despite travel restrictions put in place. In order to promote public health actions as risk communication, a risk evaluation was conducted. A descriptive analysis was carried out: personal and vaccination data were collected; for cases, date and type of positive tests, date of symptoms’ onset were collected; for high-risk contacts, date and type of negative tests at the end of follow-up were collected. Frequencies were calculated.
Results
Six journeys back from Medjugorje were identified, with at least one positive case. All trips took place between 18/09/2021 and 29/10/2021. 31 positive cases out of 160 travellers were identified, with number of cases per travel ranging from 1 to 11.
Lessons
Religious MG represent an important global health issue. Even though a specific surveillance was not activated, international contact tracing activities turned out a great source of epidemic intelligence and consequent surveillance and control activities led to risk assessment and communication actions.
Key messages
• In the pandemic context, where travel restrictions were put in place, surveillance for Religious MG should be always implemented.
• Cooperation among all the stakeholders involved as Church, travel agency, Regional Health Systems and Government Bodies has to be promoted for specific surveillance in religious MG events.
