Objective: To investigate the HIV seroprevalence among TB patients according to the geographical location. Methods: 31 districts with well performing Tuberculosis Control Programmes on the corridors of Nacala, Beira and Limpopo and non-corridor areas of the corresponding northern, central and southern regions respectively were chosen for a cross-sectional survey of the HIV seroprevalence in TB patients. 10 experienced laboratory technicians were trained to perform 2 rapid tests (Testpack and HIV SPOT). They were accompanied by the Provincial TB and Leprosy Supervisors to the district health centers during the field work. All TB patients, irrespective of their TB classification, 15 to 59 years of age in the initial phase of treatment and those in the maintenance phase coming for clinical check ups were included in the survey. Results: From June to September 1994, 1437 TB patients (639 females and 798 males) were studied. The average age was 33 (+/- 11). 1193 new, 237 retreatment and 7 chronic cases of tuberculosis were identified. The patients of the Central Region were found to have the highest HIV seroprevalence. Beira corridor 30.3, the corresponding central non-corridor area 20.4 %). A dominance of women was observed in all areas except the northern corridor. The seroprevalence rates in the districts along the Beira corridor increased from Beira town to the Zimbabwean border (p is less than 0.001, Chi2 test for linear trends of proportions). Patients living in districts on the border of Zimbabwe, Malawi and RSA had significantly higher risks of being HIV-infected compared to those living in the other districts (OR 4.30, RR 2.89, p is less than 0.05). Conclusions: The results all for changes in the key elements of both the health policy and the TB Control programme strategy, particularly in areas with the highest HIV seroprevalence rates.
