Transient simulations, applied to a three-dimensional model of the room, considering most typical positions of two patients, investigated the airflow patterns associated with different cough conditions, in order to develop an understanding of the effects of these arrangements on the regions of droplet fallout. In the present paper the following conditions were taken into account: the negative pressure of the isolation room provides the airflow performance that effectively controls the mean free path and dispersion of particles with respect to the atmospheric standard pressure; the droplets are initially larger and the evaporation will reduce their dimension; the droplets contain glycol-proteins, lipid-proteins and lipid-glycids constituents of the mucous and also viral particles; these molecules are often very long, some of them reaching 2200 nm (Cunningham 1910; Marianne et al.	./cache/cord-005326-fsx6s913.txt	./txt/cord-005326-fsx6s913.txt
