South Africa: Shortage of drug-resistant TB treatment looms

While countries are rolling out new tests that will enable them to diagnose more patients with drug-resistant tuberculosis (DR-TB), a worldwide shortage of the drugs to treat these patients is likely, Médecins Sans Frontières (MSF) warns. DR-TB can occur when TB patients do not complete their initial course of TB treatment. The only way to test for DR-TB is through cultures or via molecular testing – neither of which has been widely available in many high incident countries - until the advent of the GeneXpert, a two-hour molecular TB test released in 2010.
