Low estimates of HIV seroconversions among clients of a drug treatment clinic in San Francisco, 1995 to 1998.

摘要: We estimated HIV incidence among injection drug users attending a treatment clinic in San Francisco from 1995 to 1998 using two methods. An anonymous sequential testing method identified no seroconversions clients seen more than once during the period (one-sided upper 95% confidence limit 1.02 per 100 person-years). A sensitive/less sensitive immunoassay strategy detected early infections 1.90% year). Methods were concordant and feasible setting. Although detection of new this population (IDUs) is encouraging, epidemiologic studies IDUs not are needed monitor epidemic effectively.
