Assessment of Knowledge and Attitude of Tuberculosis Patients in Direct Observation Therapy Program towards Multidrug-Resistant Tuberculosis in Addis Ababa, Ethiopia: A Cross-Sectional Study.

Background: Multidrug-resistant tuberculosis (MDR-TB) is becoming a major challenge of tuberculosis (TB) control program globally but more serious in developing countries like Ethiopia. In 2013, a survey result showed that in Ethiopia, tuberculosis patients from new cases and retreatment cases had resistance to at least isoniazid and rifampicin with a significant increase over time. Inadequate knowledge and wrong perception about MDR-TB by patients were detrimental to TB control programs.
