NEW YORK (Reuters Health) – More than 90% of children with multidrug-resistant tuberculosis (MDR-TB) can be treated successfully, according to a study from South Africa.

Pyrazinamide resistance among Mycobacterium tuberculosis complex (MTBC) organisms increased from 2.0% in 1999 to 3.3% in 2009, according to a report from the U.S. Centers for Disease Control and Prevention.

Though we still do not have a point of care diagnostic that is cheap, fast, and detects all TB including in people with HIV and children, there has been some improvement in diagnosis with direct nucleic acid amplification testing as the following article shows.
