In many outbreaks, patients and healthcare workers are particularly at risk from nosocomial infections as a result of non-effective disinfection methods. With increasing incidence of viral infections such as severe acute respiratory syndrome, in one hand, and the increase in the rate of antibiotic resistant bacteria associated with nosocomial infections in other hand, there is a need to design novel engineering tools for inactivation of nosocomial pathogens. Ultraviolet germicidal irradiation (UVGI) is considered as a promising method to inactivate bacteria and viruses. This paper presents UV-C Based disinfection tools monitored by mobile application, designed for hospital and Epidemic Treatment Center. The evolution of the irradiation intensity over time was evaluated, and the theorical disinfection duration for several nosocomial pathogens was determined. In the case of SARS-CoV2, less than 12 minutes were needed to achieve 99.99% viral reduction in a room of 36 sqm.
