Abstract Objective To monitor the drug resistance of tuberculosis in Zhejiang Province and to provide scientific evidence for the control of drug resistant tuberculosis.Methods Thirty counties in Zhejiang Province were selected as sample during July 1, 2013 and June 30 2014, and smear positive cases were selected to be monitored during study period.Results The rate of drug resistance was 30.88%, and the rate of multi drug resistance was 5.02%. The rate of the extensively drug-resistant tuberculosis was 0.32%. Among initial treatment cases, the rate of drug resistance was 29.22%, higher than 2008, and the rate of multi drug resistance was 3.21%.Among retreatment cases, the rate of drug resistance was 45.74%, and the rate of multi drug resistance was 21.28%. All kinds of monitored drugs were found resistance phenomenon. The drug resistant rate of SM was highest (15.28%), and aminoglycosides (2.35%) were relatively low.Conclusion The status of retreatment TB drug resistance suggested that we had reduced acquired TB drug resistance through implementation of DOTS strategy and standard short course chemotherapy treatment in Zhejiang Province. But it is still not optimistic to control TB drug resistance, and the status of initial treatment TB resistant suggested that resistant strains spread had not been effectively controlled in Zhejiang Province. So we should strengthen the early detection of drug resistant among TB patients,and to further improve the standard of conventional TB treatment.
