infektime
InfekTime is a term used in epidemiological modeling to denote the estimated time of infection for an individual within a transmission chain. It is an inferred latent variable distinct from the onset of symptoms or from a positive test date.
Definition: InfekTime for person i is the time point when the infection occurred, usually represented as a
Calculation: InfekTime is inferred from data such as exposure windows, contact networks, dates of symptom onset,
Applications: It supports reconstruction of transmission trees, estimation of generation time, assessment of intervention timing, and
Relationship to other concepts: It is related to, but distinct from, the incubation period (infection to symptoms)
Limitations: Estimation relies on accurate data and explicit model assumptions; results carry substantial uncertainty, especially with
Notes: In some literature, infection timing is referred to more generically; InfekTime is a name used in
