Malawi: HIV creates TB crisis

When the first cases of extremely drug-resistant tuberculosis (XDR-TB) were reported in South Africa in 2006, the World Health Organisation (WHO) urged other countries in the region to improve their laboratory capacity and implement infection control measures. But Malawi still cannot test for the virtually untreatable TB strain. Multidrug-resistant TB (MDR-TB) strains cannot be treated by at least two of the main first-line TB drugs, while XDR-TB is resistant to most first and second-line drugs, severely limiting treatment options.
