ABSTRACT:
Currently, the risk of aerosol transmission of respiratory viruses such as SARS-Cov-2 indoors is recognised. Therefore, the objective of this work is focused on the study of small and poorly ventilated indoor spaces with low concurrent use, to find out if it is possible in a simple way to obtain at least an orientation of the potential risk for users at each moment of use. The methodology is based on the study of the existing bibliography, analysing models, equations, and calculations to find out if it is possible to use any of them to the case and that at the same time does not present excessive complexity. The results and conclusions indicate that there are clear limitations (fluid dynamics- aerodynamic, influence by temperature, light and humidity, or situations in which the user speaks, sings, shouts, coughs, or sneezes), but useful approximations can be offered regarding the risk of use.
