When we implement programs, we bring people like Dr. Fanning and Dr. Hershfield in to actually deliver those national TB programs. So we use the best practices that have been used here in Canada, that have been tested out, that have been proven to work. Exactly what Dr. Hershfield said—and I'm sure Dr. Fanning can elaborate—those are the steps.
We work with national TB programs to not only adopt those steps but to build the capacity and involve communities. I think somebody else was talking about this. If you involve communities and train them, they don't all have to be doctors, but we do have to involve an interdisciplinary team to approach that: laboratories, nurses, doctors, and community health workers. And it works, but it has to be a comprehensive investment.
Perhaps Dr. Fanning or Dr. Hershfield could comment, but one of the examples is Guyana, where I worked with Dr. Hershfield. I know the Canadian Lung Association has done considerable work in Ecuador, and Dr. Fanning has worked elsewhere.
If you go in with that approach, it does work, but it requires continued investment. You can see in Canada what the result was when that didn't happen.
