Objective To understand the prevalence of Mycobacterium tuberculosis among students in Anhui University. Methods using tuberculin (PPD, referred to as knot element) test method. Results PPD test negative reaction was 46.90%; induration 5 ~ 9mm accounted for 6.40%; 10 ~ 14mm accounted for 22.33%; 15 ~ 19mm accounted for 17.64%; ≥ 20mm accounted for 7.5 4%. There was no significant difference in the positive rate among the three grades (P> 0.05). There was no significant difference in gender response between men and women (P> 0.05). Conclusions The uninfected rate of TB in students is lower than that of the whole country, with a strong positive rate of 25.18%, suggesting that primary, secondary and drug-resistant BCG should be done according to the procedure of planned immunization.
