Abstract

The aim of the study was to determine the viral frequency and clinical-epidemiological characteristics in the episodes of acute respiratory infection in patients of the Instituto Nacional de Salud del Niño San Borja in Lima, the information of the episodes of patients who required at least one direct Immunofluorescence test from January 1, 2017 to December 31, 2018 was analyzed. 1153 episodes were identified in 707 patients. The median age was 1 year and 55% were male. The viral frequency was 13.4%; respiratory syncytial virus was identified in 10.7% of the episodies. The viral frequency was higher in children under 1 year of age (16.2%); in those with congenital disease respiratory (38.9%) and during the autumn (24.2%). The most common symptoms were cough (70.3%) and fever (53.4%); and the main diagnoses, viral pneumonia (31.8) and bronchiolitis (23.4%). It is concluded that the respiratory viral frequency was related to age, seasonality and pre-existing pathology.
