Estudio del niño en contacto con paciente tuberculoso

Abstract

Tuberculosis (TB) is a worldwide infectious disease, caused by Mycobacterium tuberculosis (Koch bacilli), that has re-emerged since the decade of the 80's in relation to the pandemic of HIV infection. Chile has one of the lowest TB prevalence rates in Latin America. In children, TB exhibits some differences from adult disease in terms of pathogenesis, clinical manifestations and probability of progression from the infected state to disease, making it more difficult to diagnose and increasing the likelihood of developing the disease once the infection is acquired. There is a National Program for the Prevention and Control of TB that allows us to develop prevention and chemoprophylaxis strategies. This article summarizes these strategies to guide the study and management of children in contact with TB patients.
