Objective To observe the trend of tuberculosis epidemic in Henan Province in recent years. Methods The infection rate of 13-year-old children without history of childbirth was monitored for 4 consecutive years from 1995, and the annual infection rate was calculated. The results were compared with the results of the third season from 1979 to 1990. Results From 1995 to 1998, the infection rates of tuberculosis were 60%, 63%, 6.5% and 59%, respectively. The calculated annual infection rates were 047%, 050%, 052% and 047%, respectively. Compared with the results of flow adjustment in 1990, it was significantly lower (P <0.01). The annual rate of decline in annual infection rates was 49% from 1985 to 1990 and 149% from 1990 to 1995.
