The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
Egg incubation, sitting on or brooding the eggs of birds and other egg-laying animals to hatch them; Incubation (psychology), the process of thinking about a problem subconsciously while being involved in other activities; Incubation period, medical term for the time between being exposed to infection and showing first symptoms
Understanding this incubation period—the time between when a virus enters a person’s body and when they start feeling sick—is crucial for health officials trying to make decisions about how ...
By convention, a communicable disease outbreak is declared over when a period of twice the incubation period of the infectious disease has elapsed without identification of any new case, however, for organisms with a short incubation period (e.g. fewer than ten days), a period of three times the incubation period is preferred.

Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. [2]
The time interval from the time of invasion by an infectious pathogen to the time of onset (first appearance) of symptoms of the disease in question is called the incubation period. [3] After the incubation period is over, the host enters the symptomatic period. Moreover, at a certain point in time after infection, the host becomes capable of ...
The incubation period is determined by the exponential growth rate, and in vivo data on prion diseases in transgenic mice match this prediction. [67] The same square root dependence is also seen in vitro in experiments with a variety of different amyloid proteins. [68] The mechanism of prion replication has implications for designing drugs.
