Extrinsic incubation period

英语百科

Incubation period

In some diseases, as depicted in this diagram, latent period is shorter than incubation period. A person can transmit infection without showing any signs of the disease. Such infection is called subclinical infection.

Incubation period is the time elapsed between exposure to a pathogenic organism, a chemical or radiation, and when symptoms and signs are first apparent. In a typical infectious disease, incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host.
