PIP: Two methods to estimate the incidence of HIV-1 infection among adults from age-specific prevalence data derived in stable endemic conditions are presented and tested on data from Kampala, Uganda. The Cumulative Incidence and Survival Method is first proposed which treats HIV-1 prevalence at any given age as the cumulative incidence of new infections at each preceding age, adjusted for mortality. A model for age-specific incidence is fitted to the data using maximum likelihood techniques. The Constant Prevalence Method is then presented in which the incidence of new infections within a given time interval is calculated as the difference, after adjusting for mortality, between observed prevalence levels at two successive age intervals, whose mean ages are a specified number of years apart. Plausible estimates of age-specific and cumulative HIV-1 incidence were obtained from each method.
