- Adenovirus-adenovirus infections in humans are usually self-limiting but the virus frequently establishes a latent, persistent infection of the tonsils and the adenoids.he virus may exist in a truly latent noninfectious occult form, possibly as an integrated genome or an episomal agent, or as an infectious and continuously replicating agent, termed a persistent viral infection.
