Niu J, Rodriguez JA, Sareli C, et al. - The risk of coronavirus 19 (COVID-19) infection may be significant in first responders (FRs) relative to the general population due to job-related exposures. Researchers here examined the prevalence and exposure patterns of COVID-19 among FRs. Between March and April 2020, real-time reverse transcription polymerase chain reaction assay was performed using nasopharyngeal swabs to screen a total of 3,375 FRs for COVID-19 infection. Findings revealed an overall infection rate of 8.6% at the time of COVID-19 testing among FRs in Broward County, FL, and asymptomatic FRs accounted for 81.3% of infection. They emphasize active surveillance to focus on the asymptomatic FRs with COVID-19.
