[{"arm_notes": "", "treatment_id": null, "treatment_name": "Our aim is to evaluate the respiratory viral epidemiology in residential aged care facility (RACF) environments and determine the potential of readily translatable measures to address airborne components of transmission within these settings.The study is a 4-period parallel cross-over randomised controlled trial targeting air-sterilisation strategies to reduce the burden of airborne viral infections in residential aged care settings. The intervention will use commercially available upper-room germicidal ultraviolet (GUV). Commercially available upper-room GUV (with effective air-mixing) has been shown to reduce airborne tuberculosis transmission at a rate equivalent to adding significant room air changes per hour; and its high efficacy against airborne viruses (including influenza and SARS-CoV-1) has been demonstrated. Moreover; when GUV has been deployed in \"in-duct\" or standalone systems; it has been shown to result in significant reductions in both viral viability and rates of symptomatic respiratory infections. These GUV modalities might therefore be combined to achieve effective air disinfection in accordance with aged care facility layout; occupancy; and air-ventilation systems. Each residential aged care facility will have the option to receive all forms of GUV intervention; with final layouts and suitability to retrospectively install determined by facility and GUV engineers. The intervention approach may use a combination of: 1. in-duct GUV placed prior to air return vents in systems serving shared spaces (such as dining areas); 2. ceiling/wall-mounted GUV units situated in a pattern that provides air sterilisation of connecting corridors and spaces between resident rooms; with additional units providing coverage to high traffic spaces (", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
