[Incidence of tuberculous infection in Caracal in 2000].
Taking into consideration the informational value of the yearly risk of tuberculous infection as an isolated epidemic indicator which is able to define by itself the present phase and the trends of the tuberculous endemic in a population, we tried to establish its value at the first grade pupils in the city of Caracal by using two methods: 1. the indirect one starting from the prevalence of infection using the A. Lotte formula: YRI = 1.24% +/- 0.45, p = 0.05, s = 0.32, Es = 0.16 (the average level in 1992, 1993, 1994, 1999 and 2000); 2. the direct one, by testing with tuberculin a group of 184 pupils twice at one year's interval. YRI = 2.65% in 1999/2000. By using the student test we demonstrated that the two values are statistically different, without being able to state which one is closer to reality, but irrespective of the chosen value, to reach the present level of yearly tuberculous infection of the western countries we need about ten to twenty years, if we admit that beginning from this moment the annual decrease will be maximal (14%).
