Tuberculosis: 13. Control of the disease among aboriginal people in Canada.

Case 1: A 36-year-old aboriginal woman has a 12-mm-diameter reaction to a tuberculosis (TB) skin test, done as part of a community survey. She was vaccinated with BCG (bacille Calmette-Guerin) at 6 weeks of age. There is no documented history of contact with TB, and no skin tests were carried out previously. The woman9s family doctor wonders about the significance of the result. Case 2: A 27-year-old aboriginal man presents with a 6-week history of cough and fever and recent onset of hemoptysis. He has recently completed 2 courses of antibiotics, but there has been no improvement in symptoms. Chest radiography shows right upper lobe pneumonia. A further course of antibiotics is prescribed. What investigations should be completed next? Case 3: The mother of a 2-day-old aboriginal infant asks for advice about the benefits of BCG vaccination. She is confused about the side effects of BCG and its effectiveness.
