ABSTRACTIntroduction: The World Health Organization estimates 156 million cases of community-acquired pneumonia (CAP) per year; in 70% of the cases, the etiology is viral. The aim of this study is to describe the epidemiology of viral pneumonia in a tertiary hospital in Mexico. Material and methods: Observational, descriptive and retrospective study from 2012 to 2016. We included 183 patients with a clinical diagnosis of viral pneumonia and a positive polymerase chain reaction (PCR) during their hospitalization. Results: The mean age of the patients was 21 ± 6 months; 57% were males. Respiratory viruses were reported in the following order: rhinovirus/enterovirus 37.7%, RSV 19%, metapneumovirus 14.8% and seasonal influenza (H1N1, H3N2, B) 14.8%, mainly; rhinovirus/enterovirus (62%) and RSV (30%) were associated with coinfection. Conclusion: The study determined the etiology and frequency of the main viral agents detected by PCR in a referral center in Mexico, and the viral coinfections and seasonality as well. The use of molecular tests must be mandatory in order to perform prospective studies on a larger scale.
