Etymology
Infectivity comes from the root infect, made of Latin parts in- 'into' and facere 'to make', and the old idea was like 'tainting' or 'staining' something. So infectivity is the power of a germ or disease to 'spread the stain' to other people, which is why it means how easily a disease can spread.
