Beruflich erworbene SARS-CoV-2-Infektionen bei medizinischem Personal in Frankfurt am Main von März bis August 2020

BACKGROUND: Standardised surveillance of COVID-19 infections among healthcare personnel during the current pandemic was and is not available. In particular, the proportion of occupational infections among healthcare personnel and which workers among them are most at risk remains unclear. OBJECTIVES: The aim of this study was to analyse the reported COVID-19 cases among healthcare personnel in Frankfurt/Main during the first six months of the pandemic, to determine the number of occupational infections and thus to allow a better interpretation of the data published by the Robert Koch Institute. METHODS: Data from the Frankfurt/Main Health Protection Authority was analysed for the period from 1 March to 31 August 2020, and healthcare personnel were recruited for a cross-sectional survey. Three subgroups were defined and analysed according to whether the infectious contact occurred at work, in private or in an unknown setting. RESULTS: Healthcare personnel accounted for 11.8% (319/2700) of all reported COVID-19 cases in Frankfurt/Main during the period studied. In the survey, 47.2% of respondents reported that their infection was acquired in the workplace. There was an association of contact with COVID-19 patients as well as employment in the internal medicine ward and a reported work-related infection. Also apparent was an association between suspected occupational infections and consequently filed reports for alleged occupational disease. DISCUSSION AND CONCLUSION: Health protection authorities are in a position to collect relevant data on work-related transmissions in healthcare occupations and workplaces and should generate standardised data on infected healthcare personnel. This data is necessary to take targeted infection control and prevention measures that protect healthcare personnel and their patients.
