It's safe to say that they were speaking from the perspective of developed countries where the mortality rate of TB is roughly 0.2 per 100,000. Which makes the case that we know how to make it statistically insignificant, but the infrastructure to apply that knowledge is not perfectly distributed.

But that's just creatively selecting the data that supports the point. You can do that with everything else. We solved a lot of things "in the lab" or "in mice".
Did you know that we conquered Alzheimer's? It's safe to say I mean in countries like Guinea-Bissau, Somalia or Chad with under 100 cases per 100k people.

TB is weird. We do indeed know how to actively manage it (e.g. screen people regularly and treat detected cases), but countries like the US don’t do that. Nonetheless TB does not cause much disease in the US.
Every time I’ve tried to figure out why this is, I’ve come to the tentative conclusion that no one really knows. Maybe it’s the general lack of malnutrition?
