Objective  To analyze the prevalence of pulmonary tuberculosis (TB), multidrug-resistant tuberculosis (MDR-TB), and TB/human immunodeficiency virus (HIV) co-infection among general and migrant population in Guizhou province for providing evidences to the control of TB epidemic.

  Methods  From National Tuberculosis Control Information System, we collected following surveillance data of Guizhou province: migrant population during 2011 – 2017, MDR-TB incidents during 2012 – 2017, and incidents of TB/HIV co-infection during 2006 – 2017. Percentage analysis and chi-square test were adopted in statistics analysis.

  Results  The reported TB incidence rate in the migrant population increased from 27.29/100 000 in 2011 to 30.03/100 000 in 2017 (χ²_trend = 134.99, P < 0.05) and the highest rate was 32.95/100 000 in 2015. During the period, the yearly number of migrant active TB patients accounted for 20% – 25% of the yearly number of total TB patients. Among the 7 146 TB patients with drug sensitivity test during the period, the total drug resistance rate and multidrug resistance rate were 23.34% and 8.13%, respectively, and there were significant differences in the total drug and multidrug resistance rate between the initial treatment and retreatment TB patients (both P < 0.05). The proportion of HIV infection among the all reported TB patients increased significantly from 0.22% in 2006 to 0.33% in 2017 (χ²_trend = 41.34, P < 0.05), with the lowest annual proportion of 0.11% and an overall increase of 0.22% during the period.

  Conclusion  The reported TB incidence rate among migrant population, the rate of MDR-TB and the ratio of TB/HIV co-infection among the reported TB cases, and the proportion of migrant TB cases in all TB patients increased in Guizhou province from 2006 to 2017. The results suggest that full-course treatment under supervision should be strengthened among migrant TB patients and control the increase in MDR-TB and TB /HIV co-infection in the population.
