Personal Protective Equipment (PPE) - Under High Air Hygiene
Intervention Description
Intervention Recipients (IRs) will be required to wear a lightweight plastic face shield, comply with hand hygiene (i.e., using a hand sanitization product every 15 minutes, plus periodic hand washing with soap and water), and avoid face touching during each planned exposure event. The face shield may only be removed after leaving the exposure room to go to the bathroom, for other short comfort breaks, and at mealtimes. In these instances, hand hygiene will be used after removing or replacing the face shield; and Donors will not be present. Hand washing with soap and water will be required before meals. IR will be separated from Donors by more than 6 feet during meals. The exposure room will be supervised by a trained member of the study staff who will monitor to ensure that Intervention Recipients wear the face shield continuously, are separated from Donors at meals, and do not touch their faces. High air hygiene is achieved by filtration and/or use of germicidal UV-C.
