[Yield of active search of tuberculosis in a marginal population].
OBJECTIVE
A prevalence study on tuberculosis infection among school-children in our area. A study of the family, contacts and teachers of infected children. An analysis of the level of compliance with diagnostic and therapeutic procedures.


METHODS
Observational and descriptive. Clinical-epidemiological.


METHODS
An urban Basic Health Area with 18,000 inhabitants.


METHODS
393 people were included in the study: 162 school-children doing first-year EGB [c. six years old], 199 family members and contacts of the infected children and 32 EGB teachers.


RESULTS
Mantoux intradermoreaction. Application of the study procedure. Following of the evolution and monitoring of the treatment. We found 6 infected children (3.7% of the school-children), all of whom came from the same marginalised area. Among the 231 family members, contacts and teachers studied, we found 30 cases of active Tuberculosis (13%) and 71 cases of infection (30.7%). Antituberculous treatment was indicated for all cases of illness and secondary Chemoprophylaxis for 49 cases. The study could not be completed in 62 cases.


CONCLUSIONS
The prevalence of tuberculous infection among school-children from the marginalised area is high. Examination of the infected childrens' contacts showed a high level of tuberculous infection. Follow-up of the diagnostic and therapeutic procedures was incomplete for a significant percentage of those under study.
