 AB    OBJECTIVES. The purpose of the study was to estimate the number of
       injection drug users infected with the human immunodeficiency virus
       (HIV) in Bangkok to allow planning for health services for this
       population. METHODS. A two-sample capture-recapture method was used. The
       first capture listed all persons on methadone treatment for opiate
       addiction from April 17 through May 17, 1991, at 18 facilities in
       Bangkok. The second capture involved urine testing of persons held at 72
       Bangkok police stations from June 3 through September 30, 1991. Persons
       whose urine tests were positive for opiate metabolites or methadone were
       included on the second list. RESULTS. The first capture comprised 4064
       persons and the recapture 1540 persons. There were 171 persons included
       on both lists, yielding an estimate of 36,600 opiate users in Bangkok.
       Existing data indicate that 89% of opiate users in Bangkok inject drugs
       and that about one third are infected with HIV, yielding an estimate of
       approximately 12,000 HIV-infected injection drug users in Bangkok in
       1991. CONCLUSIONS. During the 1990s the number of cases of acquired
       immunodeficiency syndrome (AIDS) and other HIV-related diseases,
       including tuberculosis, in the population of HIV-infected injection drug
       users in Bangkok will increase dramatically, placing new demands on
       existing health care facilities. The capture-recapture method may be
       useful in estimating difficult-to-count populations, including injection
       drug users.
