Incubation period is the time elapsed between exposure to a pathogenic organism, a chemical or radiation, and when symptoms and signs are first apparent. The period may be as short as minutes to as long as thirty years in the case of variant CreutzfeldtJakob disease.

An incubation period is the time between exposure to a disease-causing organism and the onset of symptoms. The incubation period for the molluscum contagiosum virus (MCV) ranges from two weeks to six months, but is usually between two and seven weeks, making it difficult to determine where, when, and how someone was infected.
