asymptomatic infection

Unnoticed disease presence

An asymptomatic infection is one that produces no noticeable symptoms in the infected person.

The pathogen is present and may be transmissible to others, but the host feels fine: She had an asymptomatic infection and didn't know she was contagious.

Asymptomatic cases complicate disease control because carriers spread illness unknowingly.
