Yes. To reiterate, from 1960 to 1980, the great physician, Stefan Grzybowski, oversaw a very aggressive medical program for TB under very difficult social circumstances in what is now Nunavut--poorer housing and nutrition, etc., than we have today--and they achieved the most remarkable decrease in the incidence of TB recorded in the world. So yes, it can be done. Of course, working on the social determinants is a justice issue and a credibility issue with aboriginal people. You won't get cooperation on one field if you don't address the other field. So it's the right thing to do, but the medical intervention works.
