  1. The AIDS epidemic in India : a new method for estimating current human immunodeficiency virus (HIV) incidence rates.

    Article - En anglais

    Human immunodeficiency virus (HIV) incidence rates in India were estimated using a new method that accounts for follow-up bias.

    Follow-up bias arises in epidemiologic cohort studies when the incidence rate among individuals who do and do not return for follow-up are different.

    The new method combines data on the prevalence of p24 antigenemia among all those initially screened together with the longitudinal follow-up data on the subset of patients who returned for follow-up.

    Using these methods, the current HIV incidence rate among patients attending sexually transmitted disease clinics in Pune, India, was 18.6% per year.

    It was found that follow-up bias can cause significant underestimation in HIV incidence rates, perhaps by as much as 60%. These incidence estimates, together with other HIV seroprevalence studies, suggest the HIV epidemic in India is growing rapidly.
