ABSTRACT: 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.
