Malgré un contact étroit avec le grand public, les membres du service d’incendie de San Francisco (SFFD) ont signalé relativement peu de cas de COVID-19 au cours du premier semestre de 2020. Notre objectif était d’explorer les preuves d’infections antérieures non détectées en menant une enquête de séroprévalence, et de documenter les facteurs de risque et de protection d’une infection antérieure au COVID-19.
Objectives: Despite having close contact with the general public, members of the San Francisco Fire Department (SFFD) reported relatively few cases of COVID-19 during the first half of 2020. Our objective was to explore evidence for prior undetected infections by conducting a seroprevalence survey, and to document both risk and protective factors for prior COVID-19 infection. Methods: This cross-sectional study assessed workplace practices and exposures of SFFD personnel during the first 6 months of 2020 via questionnaire and documented prior COVID-19 infections by serologic antibody testing using an orthogonal testing protocol. Results: Of 1231 participating emergency responders, three (0.25%) had confirmed positive COVID-19 antibody results. Conclusions: Safe workplace practices, community public health intervention, and low community infection rates appear to have been protective factors for emergency responders in San Francisco during our study period.
