RESUMO
We surveyed for serologic evidence of either HIV-1 or HTLV-I/II infection in 387 male veterans who entered into an inpatient drug treatment center. Serum was obtained after receiving written informed consent. Serum specimens were tested by enzyme-linked immunosorbent assay for antibody to HIV-1 and for antibody to HTLV-I/II; sera that were repeatedly reactive were then tested by Western blot (HIV-1/HTLV-I/II) and radioimmunoprecipitation assay (HTLV-I/II). Sixty-five of 387 (16.79%) patients were tested and confirmed as positive for HTLV-I/II only antibodies and 30 of the 387 (7.75%) were positive for HIV-1 only antibodies. An additional nine patients (2.32%) were seropositive for antibodies to both viruses. A statistically significant difference in the CD4/CD8 lymphocyte ratio was associated with HIV-1 seropositivity. HTLV-I/II seropositivity was strongly associated with black race, age, and duration of i.v. drug use, but not with sexual intercourse as determined by lifetime history of number of sexual partners, incidence of sexually transmitted diseases, type of drug used, or needle-sharing practices.

An outbreak of influenza A/Philippines H3N2 at a 1156-bed Veterans Administration Hospital involved 118 hospital personnel and 49 patients. Prospective surveillance methods that had been established within the hospital were not useful in identifying the number of involved individuals. Community indicators of influenza, which were reviewed retrospectively, would not have identified circulating influenza in this population. Control of the outbreak was accomplished using a creative approach that immunized over a third of the physician and nursing staff. This immunization program was successfully used in subsequent years to increase personnel compliance with the Immunization Practices Advisory Committee recommendations to annually immunize hospital personnel.
