    Background: Acute respiratory infections (ARIs) represent an important cause of morbidity and mortality in children, remaining a major public health concern, especially affecting children under 5 years old from low-income countries. Unfortunately, information regarding their epidemiology is still limited in Peru. Methods: A secondary data analysis was performed from a previous cross-sectional study conducted in children with a probable diagnosis of Pertussis from January 2010 to July 2012. All samples were analyzed via Polymerase Chain Reaction (PCR) for the following etiologies: Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza 1 virus, Parainfluenza 2 virus, Parainfluenza 3 virus, Mycoplasma pneumoniae and Chlamydia pneumoniae. Results: A total of 288 patients were included. The most common pathogen isolated was Adenovirus (49%), followed by Bordetella pertussis (41%) from our previous investigation, the most prevelant microorganisms were Mycoplasma pneumonia (26%) and Influenza-B (19.8%). Coinfections were reported in 58% of samples and the most common association was found between B. pertussis and Adenovirus (12.2%). Conclusions: There was a high prevalence of Adenovirus, Mycoplasma pneumoniae and other etiologies in patients with a probable diagnosis of pertussis. Despite the presence of persistent cough lasting at least two weeks and other clinical characteristics highly suspicious of pertussis, secondary etiologies should be considered in children under 5 years-old in order to give a proper treatment.Peer ReviewedPostprint (published version

    Objective: To study the presence of 8 respiratory viruses (Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza-1, Parainfluenza-2 and Parainfluenza-3) and atypical bacteria (Mycoplasma pneumonia and Chlamydia pneumonia) in samples from Peruvian children under 5 years-old previously analyzed for Bordetella. Pertussis. Methods: A secondary data analysis was performed from a previous cross-sectional study conducted in children with a probable diagnosis of Pertussis from January 2010 to July 2012. All samples were analyzed via Polymerase Chain Reaction (PCR) for the following etiologies: Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza 1 virus, Parainfluenza 2 virus, Parainfluenza 3 virus, Mycoplasma pneumoniae and Chlamydia pneumoniae. Results: A total of 288 patients were included. The most common pathogen isolated was Adenovirus (49%), followed by Bordetella pertussis (41%) from our previous investigation; the most prevalent microorganisms were Mycoplasma pneumonia (26%) and Influenza-B (19.8%). Coinfections were reported in 58% of samples and the most common association was found between B. pertussis and Adenovirus (12.2%). Conclusions: There was a high prevalence of Adenovirus, Mycoplasma pneumoniae and other etiologies in patients with a probable diagnosis of pertussis. Despite the presence of persistent cough lasting at least two weeks and other clinical characteristics highly suspicious of pertussis, secondary etiologies should be considered in children under 5 years-old in order to give a proper treatment.Objetivo: Estudiar la presencia de 8 virus respiratorios (Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza-1, Parainfluenza-2 y Parainfluenza-3) y bacterias atípicas (Mycoplasma pneumoniae y Chlamydia pneumonia) en muestras de niños peruanos menores de 5 años analizados previamente para Bordetella pertussis Métodos: se realizó un análisis de datos secundarios de un estudio transversal previo realizado en niños con un diagnóstico probable de Pertussis desde enero del 2010 hasta julio del 2012. Todas las muestras se analizaron mediante reacción en cadena de la polimerasa (PCR) para las siguientes etiologías: Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, virus Parainfluenza 1, virus Parainfluenza 2, virus Parainfluenza 3, Mycoplasma pneumoniae y Chlamydia pneumoniae. Resultados: un total de 288 pacientes fueron incluidos en el estudio. El patógeno aislado más común fue el Adenovirus (49%), seguido de Bordetella pertussis (41%) de nuestra investigación previa; los microorganismos más prevelantes fueron Mycoplasma pnemoniae (26%) e Influenza-B (19.8%). Las coinfecciones fueron reportadas en el 58% de las muestras y la asociación más común se encontró entre B. pertussis y Adenovirus (12.2%). Conclusiones: hubo una alta prevalencia de Adenovirus, Mycoplasma pneumoniae y otras etiologías en pacientes con un diagnóstico probable de pertussis. A pesar de la presencia de tos persistente que dura por lo menos dos semanas y otras características clínicas altamente sospechosas de pertussis, se deben considerar las etiologías secundarias en niños menores de 5 años para poder administrar un tratamiento adecuado.Tesi
