ABSTRACT
Background Healthcare workers (HCW) are at risk of getting infected with COVID-19 at work. To prevent such incidents and provide a safe environment in hospitals, comprehensive infection control strategies are necessary. We aimed to collect information on COVID-19 infection control strategies regarding personal protective equipment (PPE), regulations during breaks for HCW and dissemination of pandemic-related information. Methods We invited infection control practitioners from 987 randomly selected German hospitals in March–April 2021 to participate in our cross-sectional online survey. We categorized the hospital based on bed capacity (≤499 beds = small;≥500 beds = large). Fisher's exact test was performed and p < 0.05 defined as statistically significant. Findings 100 participants completed the questionnaire. Small hospitals were more directive about requiring FFP2 respirators (63%), whereas larger hospitals more often gave their HCW a choice between these and medical masks (67%). For the care of COVID-19 and suspected COVID-19 cases, >90% of the participants recommended the use of gloves. Notably, gloves were recommended beyond COVID-19 in 30% of the hospitals. During meal breaks various strategies were followed. Conclusion Recommendations for PPE varied across hospital sizes, which could be due to different assessments of necessity and safety. Regulations during breaks varied strongly which illustrates the need for clear official guidelines.

ABSTRACT
BACKGROUND: Mass gatherings (MGs) such as music festivals and sports events have been associated with a high risk of SARS-CoV-2 transmission. On-site research can foster knowledge of risk factors for infections and improve risk assessments and precautionary measures at future MGs. We tested a web-based participatory disease surveillance tool to detect COVID-19 infections at and after an outdoor MG by collecting self-reported COVID-19 symptoms and tests. METHODS: We conducted a digital prospective observational cohort study among fully immunized attendees of a sports festival that took place from September 2 to 5, 2021 in Saxony-Anhalt, Germany. Participants used our study app to report demographic data, COVID-19 tests, symptoms, and their contact behavior. This self-reported data was used to define probable and confirmed COVID-19 cases for the full "study period" (08/12/2021 - 10/31/2021) and within the 14-day "surveillance period" during and after the MG, with the highest likelihood of an MG-related COVID-19 outbreak (09/04/2021 - 09/17/2021). RESULTS: A total of 2,808 of 9,242 (30.4%) event attendees participated in the study. Within the study period, 776 individual symptoms and 5,255 COVID-19 tests were reported. During the 14-day surveillance period around and after the MG, seven probable and seven PCR-confirmed COVID-19 cases were detected. The confirmed cases translated to an estimated seven-day incidence of 125 per 100,000 participants (95% CI [67.7/100,000, 223/100,000]), which was comparable to the average age-matched incidence in Germany during this time. Overall, weekly numbers of COVID-19 cases were fluctuating over the study period, with another increase at the end of the study period. CONCLUSION: COVID-19 cases attributable to the mass gathering were comparable to the Germany-wide age-matched incidence, implicating that our active participatory disease surveillance tool was able to detect MG-related infections. Further studies are needed to evaluate and apply our participatory disease surveillance tool in other mass gathering settings.
