Assessing quality of life for multidrug-resistant and extensively drug-resistant tuberculosis patients.

Objective: One can hypothesize that Mycobacterium genus originated more than 150 million years ago and has evolved to become one of the leading lethal infectious diseases. Multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) patients are directly affected by the disease and other subjective issues, such as related diseases, medical costs and social issues, which all have negative impacts on patient quality of life (QOL). Our purpose is to define the status of health-related QOL for international MDR-TB and XDR-TB patients.
