Evaluation of the killing effects of UV₂₅₄ light on common airborne porcine viruses.

ABSTRACT: UV exposure is a common method of disinfection and sterilization. In the present study, the parallel beam test was performed to collect fluids containing infectious viruses using a parallel beam apparatus after UV₂₅₄ irradiation (0, 0.5, 1, 3, 5, 7, 10, or 20 mJ/cm²). The air sterilization test was performed by irradiating the air in the ducts with UV₂₅₄ light (0, 1, 2, 3, 4, or 6 mJ/cm²) to collect airborne particles containing viruses through the air sterilization equipment. Furthermore, viral inactivation was assessed based on cytopathic effect (CPE) detection and immunofluorescent assays (IFA). Both the CPE and immunofluorescence signal intensity decreased as the UV₂₅₄ dose increased. The UV₂₅₄ doses required to inactiva
