Mr. Chairman, to provide more than a fairly basic answer, I would want to call upon some of our medical staff to advise the Member. Clearly, it is a risk whenever there are a pharmaceutical prescribed and where the course of treatment are not pursued. You run the risk of developing drug-resistant strains of the disease. In the area tuberculosis this is a very specific concern and one that clearly has drawn our attention and raise the pressure we put on boards to ensure that it does not remain an issue. Thank you.
