What is multi-drug resistance or extensive drug resistance?
Multi-drug resistant tuberculosis (MDR-TB) bacteria are resistant to the two most commonly available drugs used to fight TB: isoniazid and rifampicin. These are called first-line drugs – the ones most readily available and most often used. When David and Carlos are sent to Chiapas, the Zapatistas have already tried to treat the patients with these drugs, and found that they didn’t work.
