RESUMEN
OBJECTIVE: To examine the characteristics of foreign-born people with tuberculosis (TB) in Southern Florida, their contribution to the total number of TB cases, and available data on their HIV status as well as to determine the number of cases detected by the overseas medical screening of immigrants and refugees. METHODS: The authors reviewed TB cases reported by Broward, Dade, and Palm Beach counties in 1995. Case records were matched against the CDC Division of Quarantine database of immigrants and refugees suspected to have TB at the time of visa application overseas. RESULTS: Nearly half (49%) of TB cases in the three counties were among people born outside the United States--34% in Broward County, 58% in Dade County, and 40% in Palm Beach County. A high percentage (26%) were co-infected with HIV. Of those with known date of arrival, 68% had been in the United States for five or more years. Only three cases had been identified by overseas immigrant screening. CONCLUSIONS: A low percentage of TB cases in foreign-born people were identified through the overseas screening system. Controlling TB in South Florida will require efforts targeted toward high risk populations, including people with HIV infection.

The incidence of tuberculosis has recently risen in Southeast Florida. In order to determine the number and proportion of tuberculosis cases and the characteristics of tuberculosis that might be related to human T-cell lymphotrophic virus-III (HTLV-III) infection, all patients seen by the Dade County Florida Public Health Department-Tuberculosis Clinic during a 6-month period were medically evaluated and screened for HTLV-III antibody by an enzyme-linked immunosorbent assay. Of 71 consecutive patients confirmed to have tuberculosis (70 by culture) during the study period, 22 (31%) were seropositive and 49 (69%) were seronegative for HTLV-III antibody. The seropositive group had a significantly higher proportion of patients who were black, Haitian, and within the age group of 25 to 44 yr. The seropositive group also had a significantly higher rate of mild-to-moderate serum aspartate transaminase elevations (less than or equal to 5 times normal), tuberculin skin test false negativity, extrapulmonary tuberculosis (especially lymphatic), and pulmonary tuberculosis with an atypical radiographic picture. The seropositive group had a significantly lower proportion of patients with sputum cultures positive for M. tuberculosis. There was no significant difference between the groups with respect to the proportion of patients with positive sputum smears when sputum cultures were positive, serious antituberculosis drug reactions (requiring discontinuation of therapy), or percent of home contacts who were tuberculin skin tested and found to be positive. At the time of the diagnosis of tuberculosis, only 6 (27%) of the seropositive patients with tuberculosis had clinical evidence of AIDS or AIDS-related complex (unexplained thrush).(ABSTRACT TRUNCATED AT 250 WORDS)
