GENEVA-- A much larger tuberculosis drug-resistance problem exists than researchers previously thought. New global data on TB, published this month by the World Health Organization (WHO), highlight serious weaknesses in many national TB programs, increasing the potential for widespread TB drug resistance.

How did we reach this precarious state?

Ask a WHO expert that question and he'll assert that increasing levels of TB drug resistance "reflects a failure to implement the WHO Stop TB Strategy." The strategy hopefully maps out the steps that national TB control programs need to take. By all accounts then, our national TB programs are failing us.
