ARIAS, Patricia et al. Viral respiratory infections in hospitalized patients in a neonatal intensive care unit. Pediatr. (Asunción) [online]. 2019, vol.46, n.3, pp.165-172. ISSN 1683-9803.


Viral respiratory infections are a national problem and neonatal intensive care units are not exempt from these infections.


To describe the frequency and clinical characteristics of viral respiratory infections in newborns admitted to a Neonatology unit during january 2017 to october 2018 timeframe.

Materials and Methods:

This was an observational, descriptive and retrospective study. We reviewed the clinical records of patients admitted to the neonatal intensive care unit who were also diagnosed with a viral respiratory infection. To determine the etiology, we used direct immunofluorescence, immunochromatography and real-time PCR. Patients who were transferred from another service and whose symptoms began prior to transfer to our unit were excluded. Variables: gestational age, postnatal age, birth weight, symptoms, type of virus, antibiotic prescription. Data were analyzed with Excel, using descriptive statistics.


Of the 761 patients, 65 patients were diagnosed with a viral respiratory infection, a frequency of 8.5%. The average age was 17 ± 10 days. The most frequent diagnostic method was immunofluorescence (92%). The most common symptoms were respiratory secretions (74%) and desaturations (64%); The most frequent viruses were: Respiratory Syncytial (26%), Influenza B (25%) and Influenza A (18%). 66% required respiratory support treatment. One patient died from causes unrelated to the viral respiratory infection.


The frequency of viral infections was 8.5%. The most frequent viruses were RSV and influenza B. More than half needed respiratory support. No patient died.
