“…However, there is evidence that private community exposure may be a stronger risk factor than work exposure. (11) Exposure to at-risk-patients from high-infection regions or from dedicated COVID-19 wards, would be relevant risk factors,(12) but it is not clear what specific healthcare settings would increase the risk of infection for HWs, and who exactly are the more exposed 'frontline workers'. A study assessing COVID-19 hospital admission in Scotland (13) found that older, male HWs were more at risk of infection and hospitalization; patient-facing healthcare workers and their households were at higher risk compared with non-patient facing ones.…”

Introduction. Health workers (HWs) are a key resource for health systems worldwide, and have been affected heavily by the COVID-19 pandemic. Evidence is consolidating on incidence and associated drivers of infections, predominantly in high-income settings. It is however still unclear what the risk factors may be for specific health professions, particularly in low- and middle-income countries (LMICs). Methods. We conducted a cross-sectional survey in a representative sample of 1,183 medical doctors registered with Brazil’s Federal Council of Medicine in one developed (São Paulo) and one disadvantaged state (Maranhão). Between February-June 2021, we administered a telephone questionnaire to collect data on physicians’ demographics, deployment to services, vaccination status, and self-reported COVID-19 infections. We performed descriptive, univariate, and multilevel clustered analysis to explore the association between physicians’ infection rates, and their sociodemographic and employment characteristics. A generalized linear mixed model with a binomial distribution was used to estimate the adjusted odds ratio. Results. We found that 35.8% of physicians in our sample were infected with COVID-19 in the first year of the pandemic. The infection rate in Maranhão (49.2%) [95% CI 45.0-53.4] was almost twice that in São Paulo (24.1%) [95% CI 20.8-27.5]. Being a physician in Maranhão [95% CI 2.08-3.57], younger than 50 years [95% CI 1.41-2.89], and having worked in a COVID-19 ward [95% CI 1.28-2.27], were positively associated with the probability of infections. Conversely, working with diagnostic services [95% CI 0.53-0.96], in administrative functions [95% CI 0.42-0.80], or in teaching and research [95% CI 0.48-0.91] was negatively associated. Conclusions. Based on data from Brazil, COVID-19 infections in LMICs may be more likely in those health systems with lower physician-to-patient ratios, and younger doctors working in COVID-19 wards may be infected more frequently. Such findings may be used to identify policies to mitigate COVID-19 effects on HWs in LMICs.

“… 11 This study also found no significant difference between the use of a filtering facepiece class 2 (FFP2) respirator versus the use of a surgical mask 11 which is consistent with the updated systematic review of observational studies for risk factors for COVID-19 among HCWs mentioned above, albeit recognizing the limitations of observational studies. 4 Other high quality systematic reviews have not found any differences for increased risk of transmission to HCWs for other respiratory viruses when comparing medical/surgical masks versus N95 respirators. 15 …”

“… 3 However, more recent updates of this systematic review have identified household or community exposure to SARS-CoV-2 as the strongest risk factor with adjusted odds ratios (OR) varying from 2.55-8.98. 4 In addition, more consistent use of full PPE measures and education/ training in infection prevention and control (IPC) were associated with a protective effect. 3 , 4 …”

Zusammenfassung Hintergrund Eine standardisierte Erhebung von COVID-19-Infektionen bei Gesundheitspersonal während der laufenden Pandemie war und ist nicht gegeben. Vor allem der Anteil von arbeitsbedingten Infektionen beim Gesundheitspersonal und die Frage, welche Arbeitnehmer/-innen darunter am meisten gefährdet sind, bleiben unklar. Ziel Ziel dieser Studie war es, die gemeldeten COVID-19-Fälle beim Gesundheitspersonal in Frankfurt/Main in den ersten 6 Monaten der Pandemie zu analysieren, die Zahl der arbeitsbedingten Infektionen zu ermitteln und somit eine bessere Interpretation der durch das Robert Koch-Institut veröffentlichten Daten zu ermöglichen. Methoden Die Daten des Gesundheitsamts Frankfurt/Main wurden für den Zeitraum vom 01.03. bis zum 31.08.2020 betrachtet und medizinisches Personal für eine Querschnittserhebung im Rahmen einer Umfrage rekrutiert. Drei Subgruppen wurden nach Ort des Infektionskontakts, am Arbeitsplatz, im Privaten und unbekannt, unterteilt und analysiert. Ergebnisse Medizinisches Personal machte 11,8 % (319/2700) aller gemeldeten COVID-19-Fälle in Frankfurt/Main im untersuchten Zeitraum aus. In der Umfrage gaben 47,2 % der Befragten an, dass ihre Infektion am Arbeitsplatz erworben wurde. Es zeigte sich eine Assoziation von Kontakt zu COVID-19-Patient/-innen sowie der Beschäftigung auf einer internistischen Station und einer arbeitsbedingten Infektion. Ersichtlich wurde außerdem ein Zusammenhang zwischen mutmaßlichen Infektionen am Arbeitsplatz und folglich gestellten Verdachtsanzeigen auf Berufskrankheit. Diskussion und Fazit Gesundheitsämter sind in der Lage, relevante Daten von arbeitsbedingten Transmissionen in Berufen und Arbeitsplätzen im Gesundheitswesen zu erheben, und sollten standardisierte Daten zu infiziertem Gesundheitspersonal generieren. Diese Daten sind notwendig, um gezielte Maßnahmen der Infektionsprävention zu ergreifen, die Gesundheitspersonal und ihre Patient/-innen schützen.
