The age-structure of a population, and the distribution of sexual behavior according to age, are significant factors determining the spread of the A/DS epidemic.
The threshold conditions for age-structured models account for life-history information, and thus differ significantly from their age-independent counterparts.
We examine the threshold conditions for four general age-structured models of the spread of H/V in a homosexual population: three with random partner selection and one with biased partner selection.
We consider both discrete and continuous risk groups, and the duration of infection.
Susceptibility and infectiousness are treated separately, and the infectivity varies with duration of infection.
