incubation period
Let an agent explain incubation periods, relay typical ranges and uses in public health from epidemiology sources with ranges attributed, describe intrinsic and extrinsic periods and flag the latency alias, route post-exposure care, and distinguish incubation period from latent period in epidemiology, infectious period, window period in testing and viral latency.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain incubation periods, relay typical ranges and uses in public health from epidemiology sources with ranges attributed, describe intrinsic and extrinsic periods and flag the latency alias, route post-exposure care, and distinguish incubation period from latent period in epidemiology, infectious period, window period in testing and viral latency.
The time between exposure to an infectious agent, toxin or other cause and the appearance of the first symptoms, varying by disease from hours, as with some food poisoning, to days for influenza, weeks for chickenpox and months or years for diseases such as rabies in some cases or HIV-related illness; registry aliases name the intrinsic incubation period in the human or animal host and the extrinsic incubation period of a pathogen developing in a vector such as a mosquito, while virus latency, a dormant state of viruses such as herpesviruses, is a different concept and appears loosely filed. Incubation periods inform quarantine durations and outbreak investigation, and anyone exposed to rabies risk or other serious infections should seek medical advice promptly without waiting for symptoms.
What it is for: Timing disease onset after exposure.
It can be explain the concept; relay typical ranges with attribution; describe intrinsic and extrinsic periods; route post-exposure care.
Distinguishing features
Exposure to symptom onset
Disease-specific ranges
Basis for quarantine
Distribution rather than fixed value
What it looks like
Not a physical object; a time interval shown in epidemic curves and case definitions.
Physical character
influenza incubation: about 1-4 days - typical, attributed
chickenpox incubation: about 10-21 days - typical, attributed
Sartwell incubation distribution: 1950 year - log-normal model
How it is recognised
Time from exposure to symptoms
Intrinsic incubation period, extrinsic incubation period, virus latency
The latent period is time to infectiousness; the infectious period is when spread occurs; the window period is before tests detect infection; viral latency is dormancy
