While Latent or Latency period may be synonymous, a distinction is sometimes made between Incubation period, the period between infection and clinical onset of the disease, and Latent period, the time from infection to infectiousness. Which is shorter depends on the disease.
A person may be a carrier of a disease, such as Streptococcus in the throat without exhibiting any symptoms. Depending on the disease, the person may or may not be contagious during the incubation period.
For many conditions, incubation periods are longer in adults than they are in children or infants.
