Terminal decontamination of the Royal Free London's high-level isolation unit after a case of Ebola virus disease using hydrogen peroxide vapor

Abstract

We report the decontamination of the high-level isolation unit at the Royal Free London after the discharge of a patient with Ebola virus disease, who was repatriated from West Africa. Hydrogen peroxide vapor (HPV) was used to decontaminate the patient care isolators and the rooms housing them. HPV decontamination was completed without incident and allowed the unit to be returned to service more quickly than the previous protocol of using formaldehyde.
