Combined Infection Control Interventions Protect Essential Food Workers from Occupational Exposures to SARS-CoV-2 in the Agricultural Environment
Cooper, D. K., Sobolik, J. S., Kovacevic, J., Rock, C. M., Sajewski, E. T., Guest, J. L., … Leon, J. S. (2023, June 13). APPLIED AND ENVIRONMENTAL MICROBIOLOGY.
author keywords: COVID-19; quantitative microbial risk assessment (QMRA); vaccinations; nonpharmaceutical interventions (NPIs); produce industry worker
TL;DR:
This model has demonstrated that the elevated daily SARS-CoV-2 infection risk experienced by indoor and outdoor produce workers can be reduced below 1% when vaccinations (optimal vaccine efficacy, 86 to 99%) are implemented with recommended infection control strategies (e.g., handwashing, surface disinfection, universal masking, physical distancing, and increased ventilation).
