Not caused by or related to a virus.
The doctor explained that the illness was nonviral and could be treated with antibiotics.
Nonviral → It is formed from "non-" (meaning not) and "viral" (from Latin "virus", meaning poison or toxin). The word "nonviral" means not related to or caused by a virus.
Think of 'non-' meaning not, and 'viral' relating to a virus — so nonviral refers to something that is not caused by a virus.
