ملخص: Cadre: L'Algerie est un pays a haute prevalence de tuberculose ou la vaccination BCG est appliquee a grande echelle a la naissance.Objet: Pour mesurer l'ampleur du probleme de la tuberculose et evaluer l'impact de l'application du programme national antituberculeux mis en place en 1972, une enquete tuberculinique a intervalle a ete realisee de 1980 a 1989 en Algerie.Schema: Cette enquete s'est deroulee dans les ecoles des communes de 5 zones a niveau socio-economique different. 18960 et 30738 enfants ages de 8,5 ans ont ete testes respectivement lors de deux passages a 5 ans d'intervalle. De plus, 10301 enfants ages de 12,5 ans ont ete inclus dans l'enquete lors du second passage.Resultats: La prevalence de l'infection des enfants ne presentant pas de cicatrice vaccinale, non vaccines ou dont le statut vaccinal n'etait pas connu, etait de 4,05% en 1980-84 et de 2,71% en 1985-89, et au taux de diminution annuelle de 7,8%, le risque annuel d'infection tuberculeuse etait de 0,34% en 1980-84 et de 0,22% en 85-89.Conclusions: Ces resultats laissent esperer la poursuite de la reduction du probleme de la tuberculose dans les annees futures. Ils montrent aussi qu'il est possible de realiser des enquetes tuberculiniques a intervalle dans les pays a haute prevalence de tuberculose ou la vaccination BCG est appliquee a grande echelle a la naissance.Setting: Algeria, where mass BCG vaccination is performed at birth, has a high prevalence of tuberculosis.Objective: To measure the scale of the tuberculosis problem and the impact of the National Tuberculosis Control Programme set up in 1972, a tuberculin survey was performed at regular intervals from 1980-1989 in Algeria.Design: The survey took place in the schools of five communities of differing socio-economic levels. During two visits five years apart, respectively 18 960 and 30 738 children aged 8.5 years were tested. During the second visit, 10 301 children aged 12.5 were included in the survey.Results: The prevalence of infection in children with no scar, non-vaccinated or whose vaccination status was unknown, was 4.05% in 1980-1984 and 2.71% in 1985-1989. With an annual decrease of 7.8%, the annual risk of tuberculosis infection was 0.34% in 1980-1984 and 0.22% in 1985-1989.Conclusion: The results of the survey seem to indicate the continued abatement of the tuberculosis problem in the years to come. They also show that tuberculin surveys at regular intervals can be performed in high. prevalence countries where there is mass BCG vaccination at birth.
