Contagio
Contagio, contagium, contactus, infectio, molynsis, aporrhoea, vel cocciasis, est introitus et multiplicatio actorum pestiferorum (bacteriorum, prionum, virorum, et cetera) in corpore animalis sive hominis; quae actio causa morbi esse potest. Animal huius morbi curatum saepe fit immune. Interdum contagio propter defensionem corporis non est proxima morbi causa (infectio silens), qui autem post multos annos apparet (e.g., SCDI).
