ABSTRACT
It is very difficult to calculate the probability of viral infection in transport, which results from the specificity of the related processes conditioning the number of random events involving the probability of activating a virus transmission mechanism. Droplet transmission is definitely the predominant mechanism, yet the number of events involving the remaining transmission mechanisms and their relation with the daily scale of provision of all transport services cause that even seemingly small differences, ranging at tenths or even hundredths of per cent, trigger serious quantitative effects. This chapter presents universal methodology for estimating the probability of viral infection with full mathematical disclosure and an open process formula, aimed to make it possible to take specific other mechanisms of virus transmission into account when providing transport services.
