The infection is acquired from an infected organism of a particular species or from a contaminated thing. Note that the susceptible and infectious organisms can be of different species. Apollo-SV defines infection acquisition rather than infection transmission, which is the direction of movement of a pathogen in current use. The Apollo-SV conceptualization is simpler when accounting for infections acquired from contaminated things. The likelihood of acquisition is expressed by parameters such as the basic reproduction rate and transmission coefficient. An infection is acquired from an infectious organism or a contaminated thing. Cannot acquire from colonized host directly - contamination results from colonized or contaminated thing and new host picks it up from contaminated thing. Mathias Brochhausen The biological process of pathogen organism(s) of a particular biological taxon entering (the tissues of the body of) a host organism of another taxon from a contagious host or a contaminated thing and reproducing using host resources. contaminated thing susceptibility contagiousness host organism entry into host symbiont entry into host organism
