Abstract

Background: Enteroviruses (EVs) are an important cause of illness, especially in neonates and young infants. Clinical and laboratory findings at different ages, brain imaging, and outcomes have been inadequately investigated.

Methods: We retrospectively investigated EV infections occurring at an Italian tertiary care center during 2006-2017. Cases were confirmed with a positive polymerase chain reaction on blood or cerebrospinal fluid. Clinical and laboratory findings according to age at presentation were analyzed.

Results: Among 61 cases of EV infection, 56 had meningitis, 4 had encephalitis, and 1 had unspecific febrile illness. Forty-seven cases (77.0%) presented at less than 1 year of age, and most were less than 90 days of age (n = 44). Presentation with fever (p < 0.01), higher median temperature (p < 0.01), and irritability (p < 0.01) were significantly more common among infants aged less than 90 days, who also had significantly higher peak temperatures during the course of the disease (p < 0.01). In contrast, gastrointestinal symptoms were more common in infants and children aged over 90 days (p = 0.02). Only 4 of 61 infections (6.5%) were severe and all affected younger infants (p < 0.01).

Conclusions: We detail epidemiological, clinical, and laboratory findings in a cohort of 61 children. Infants aged less than 90 days have more severe disease; they are more likely to present with fever, higher median temperature, and irritability and less likely to develop gastrointestinal symptoms.
