For instance, the latent period between exposure to HIV human immunodeficiency virus infection and the onset of AIDS acquired immunodeficiency syndrome may be many years, although invasion of the body by HIV does cause a transient primary infection two to three weeks after initial exposure. Timely intervention at this stage may arrest the progress of disease.
During the latent period between initial exposure and the onset of clinically detectable disease, pathological processes may be progressing slowly and inexorably, and they may be detectable with suitable screening tests. John M. Learn more about citation styles Citation styles Encyclopedia.
However, much remains to be discovered about the natural history of many disease processes with long latent periods between exposure and the appearance of overt disease. Then, copy and paste the text into your bibliography or works cited list.
In infectious diseases it is often identical to the incubation period, but not always. Exposure to a single large dose of ionizing radiation , such as the exposure of residents of Hiroshima to the atom bomb explosion of 1945, demonstrates the variation in the latent period between exposure to ionizing radiation and the occurrence of malignancies, as well as the relationship between malignancies and radiation dose.
Last see also: Transmissable spongiform encephalopathy, caused by infectious prions, may have a latent period of up to twenty years or more.
General Latent Period. The distinction between latency and incubation is illustrated by the natural history of the asbestos-induced cancer mesothelioma, where there may have been a single finite exposure many years before the onset of malignancy.

Retrieved February 26, 2019 from Encyclopedia. In general, there is an inverse relationship between exposure dose and latent period — a high dose generally results in a short latent period, while a low dose means long latency.
