While 'shed' is clear, the specific medical context of 'shedding' in virology is not immediately obvious.

Etymology

Shedding in medicine comes from the same old root scēadan, meaning 'to separate' or 'throw off'. So viral shedding is when an infected person or animal 'lets go' of virus particles, which explains how an illness can spread.
