[Permanent environmental disinfection techniques in hospital settings with infectious risk].

While the world's economies avoid the COVID-19 pandemic blockade, there is an urgent need for technologies aimed at reducing the transmission of COVID-19 in confined spaces such as hospital environments. Although the cleaning and disinfection procedures now have rather complex and sophisticated weapons, they do not seem to be sufficient to continuously maintain low levels of environmental microbiological contamination. This result can now be achieved through the cross-use, in space and time, of improved, more efficient and effective technologies. This result can now be achieved through the cross-use, in space and time, of improved technologies. This work highlights the possibility of crossing and cooperation of different disinfection techniques, such as to keep the microbial and viral load low over time.
