Epidemiological Trends of Drug-Resistant Tuberculosis in China From 2007 to 2014 A Retrospective Study

摘要

The emergence and spread of drug-resistant tuberculosis (DR-TB) has become the major concern in global TB control nowadays due to its limited therapy options and high mortality. A comprehensive evaluation for the epidemiological trends of DR-TB in mainland China, of which TB incidences remain high, is essential but lacking. This study aimed to describe the trends of DR-TB overtime, especially multi-drugresistant TB (MDR-TB); and to identify unique characteristics of MDR TB cases compared with drug-susceptible TB cases in Mainland China.
