[Recommendations for the management of acute lower respiratory infections in children under 2 years of age. Update 2021].

Acute lower respiratory infections (ARI) continue being an important cause of morbidity and mortality in our region. Standardized case management is a valuable tool to deal with them. In addition to aspects related to the diagnosis and treatment of these diseases, the analysis of risk factors (both biological and socio-environmental) from a local and current perspective, allows the implementation of effective control and/or prevention measures, as well as identifying those patients susceptible to presenting serious forms or complications. Since 1996, the Sociedad Argentina de Pediatría asumed the challenge of generating a document that guides the comprehensive management of patients with ARI. This fourth update includes the latest advances on the subject.
