The strong positive rate was 4.73% for males and 8.27% for females,and the difference was statistically significant(P<0.05). The strong positive rate increased with the age group. Weak positive rate was highest in the 5-14 year age group(34.59%). There was no significant difference in weak positive rate and moderate positive rate between close contacts of sputum positive and negative cases(P>0.05).
