The warnings come as new antibiotics are beginning to be available for drug-resistant TB for the first time. While that is very good news, say the authors of the report, they fear that without accurate tests to establish which drugs will and which will not work in an individual patient and clear guidelines to medical staff on how they should be used, they too could lose their effectiveness.
