This simulation study, led by researchers at the Louis Stokes Cleveland VA Medical Center, Cleveland, finds that reuse of N95 masks can result in contamination of those wearing the masks and the environment, even when correct technique is used.
A total of 12 healthcare workers (HCWs) performed 3 simulated examinations with mannequins, including (1) control with suboptimal N95 handling technique, (2) improved technique with glove changes after each N95 contact, and (3) control with 1-minute ultraviolet light treatment.
Included in the findings:
Simulations with fluorescent lotion demonstrated multiple potential routes of transfer to participants, mannequin, and surfaces, including direct contact with the contaminated N95 masks and indirect contact with contaminated gloves.
The researchers concluded that reuse of N95 masks can result in contamination of personnel and the environment, even when correct technique is used. Decontamination with ultraviolet light could reduce the risk for transmission.Read More >>
