Objective To understand the prevalence of drug resistant tuberculosis(TB) in China and provide scientific evidence for the development of TB prevention and control strategy.Methods The analysis was conducted on the data of three national TB epidemiological surveys conducted in the mainland of China in 1990,2000 and 2010 to learn about the change trend of initial drug resistance and acquired drug resistance to different anti TB drugs and compare the differences in drug resistant rate and multidrug resistant(MDR) rate in 12 provinces.Results The analysis indicated that the initial resistance to isoniazid and streptomycin showed an upward trend(PPPPConclusion It is necessary to increase the coverage of standardized treatment and management MDR TB to stop the spread of MDR TB.
