The study.
This prospective, cross-sectional study conducted in Brazil sought to determine the impact of specific viruses on the severity of lower respiratory tract infection in children <3 years of age admitted to observation or inpatient units. Viral polymerase chain reaction testing on nasopharyngeal secretions was performed for a variety of common respiratory viruses. The primary outcome metric of interest was length of stay.
The key findings.
At least 1 virus was detected in 222 (85%) patients and 146 patients tested positive for multiple viruses. Respiratory syncytial virus (RSV) was the most commonly identified virus and was found in 54% of cases. Infants <6 months of age remained in the hospital 3.8 days (95% confidence interval [CI]: 2.7–5.0 days) longer than other children. A family history of asthma was linked to an extra 2.4 inpatient days (95% CI: 1.2–3.6 days). Infants with rhinovirus and RSV coinfection had longer length of stay than other infants (5.5 days longer, P <.001).
Why do we care?
Although the authors present a plethora of data regarding epidemiology of lower respiratory tract infection in infants and young children, the information …
