To determine the childhood tuberculosis prevalence and its socio-demographics factors associated to this population in Armenia (Colombia). Methodology A retrospective-descriptive study was carried out; TB patients under the age of 14 years were included and notified to the TB control program in Armenia, those who started a Directly Observed Treatment Supervised (DOTS) scheme among from 2000 to 2009 years. 58 TB cases were described, most cases have occurred in 2009 (12 cases) followed by the 2008 (8 cases) and 2006 (7 cases) respectively. Thus, Armenia has a high rate of prevalence (16.6 cases/100 000 inhabitants). Pulmonary forms had greater proportion with 74 %, of which 34 % were positive to sputum examination revealed Acid-fast bacilli (AFB). Epidemiological link allowed confirmation of 21 % of cases. TB treatment cohort revealed that 5 % of patients were cured, finished 17 %, transferred 4 %, dead 7% and in 67 % of cases the results were not documented. Nowadays TB still an important cause of childhood morbidity and mortality. The good BCG vaccine covertures and the high prevalence of pulmonary forms in childhood TB indicates that the most plausible explanation for this high prevalence is a failure in early detection of bacilli positive patients to cut recent transmission in this municipality.

Objetivo Determinar la prevalencia de tuberculosis (TB) infantil y los factores socio-demográficos asociados a esta población en el municipio de Armenia (Colombia). Metodología Se realizó un estudio descriptivo-retrospectivo en el cual se incluyeron pacientes con diagnóstico de TB menores de 14 años que fueron notificados al programa de TB en el municipio de Armenia y que iniciaron esquema de Tratamiento Acortado Estrictamente Supervisado (TAES) entre el 2000-2009. Resultados Se notificaron un total de 58 casos de TB, el mayor número de casos ocurrió en el 2009 (12 casos) seguido del 2008 (8 casos) y 2006 (7 casos) respectivamente, representando una elevada tasa de prevalencia (16,6 casos/100 000 habitantes). Las formas pulmonares tuvieron mayor proporción con 74 %, de las cuales 34 % fueron positivas a la baciloscopia (BK). El nexo epidemiológico se configuró en el 21 % de los enfermos. En cuanto al egreso del programa de control de la TB el 5 % de los pacientes finalizó con criterio de curado, 17 % terminado, 4 % transferidos, 7 % fallecidos y en el 67 % de los casos se desconoció el resultado del tratamiento. Conclusión La TB representa en la actualidad una causa importante de morbilidad y mortalidad infantil. Dada la buena cobertura de vacunación con BCG y que la mayoría de casos son pulmonares en este municipio, la alta tasa de casos de TB infantil estaría indicando fallas en la oportunidad para interrumpir transmisión reciente a partir de casos bacilíferos.
