TB is very curable in most cases. The problem is it takes a long time, the regimens can be difficult, and active cases become resistant if they're not monitored (why we use directly observed therapy), and latent cases with the typical treatment take just about as long. What we really need for TB are shorter high-efficiency regimens. These would be done quicker, leave less opportunity for drug resistance, and make progress on today's latent cases which are tomorrow's active cases. The newer 3HP regimen reduces latent treatment to 3 months instead of six to nine, but we really need to get it down to weeks or less.
