Overview

RESPROTECT is a trial aimed at evaluating the effectiveness of upper room ultraviolet devices in reducing the frequency and severity of respiratory infections in elderly nursing homes.

  • Not wishing to be equipped with UVGI devices in all rooms considered necessary to be equipped by the investigators
  • Having planned a major change to the structure (extension, renovation, closure, requalification, etc.) during the course of the study, which could affect the study population and/or UVGI air treatment devices.

Individual eligibility criteria

Individual Inclusion criteria:

All residents present in one of the participating ENH at the start of each of the two study periods, or arriving in one of the participating ENH during one of the two periods, will be eligible
