Morphology
The phrase's meaning — spread of an infection by immediate physical contact — is directly derivable from 'direct' (immediate, no one between) + 'transmission' (passing an infection). This adj+noun composition is a transparent, compositional pattern found across languages, so a B1 learner who knows both constituents will readily infer the MWE's meaning.
Etymology
Direct transmission gives a clear image: direct means straight and transmission means sending, so imagine germs being sent straight from one person to another by touch, a cough, or a shared cup. That's why it means the 'spread' of sickness from one person to another without anything in between.
