Abstract
Health care workers (HCW) are exposed to ribavirin aerosol during therapy of infants with respiratory syncytial virus infections. To assess the degree of HCW exposure, we analyzed air samples from patient rooms and HCW personal breathing zones during ribavirin aerosol delivery by ventilator (two samples), oxygen hood (two samples), and a new vacuum exhaust hood (four samples). HCW exposure to ribavirin during aerosol delivery by ventilator or vacuum exhaust hood system was substantially lower than HCW exposure during aerosol delivery by oxygen hood in rooms with adequate ventilation.
