Community-Acquired Rotavirus Gastroenteritis Compared with Adenovirus and Norovirus Gastroenteritis in Italian Children: A Pedianet Study

Abstract EN

Background.

Rotavirus (RV) is the commonest pathogen in the hospital and primary care settings, followed by Adenovirus (AV) and Norovirus (NV).

Only few studies that assess the burden of RV gastroenteritis at the community level have been carried out.

Objectives.

To estimate incidence, disease characteristics, seasonal distribution, and working days lost by parents of RV, AV, and NV gastroenteritis leading to a family pediatrician (FP) visit among children < 5 years.

Methods.

12-month, observational, prospective, FP-based study has been carried out using Pedianet database.

Results.

RVGE incidence was 1.04 per 100 person-years with the highest incidence in the first 2 years of life.

Incidences of AVGEs (1.74) and NVGEs (1.51) were slightly higher with similar characteristics regarding age distribution and symptoms.

Risk of hospitalisation, access to emergency room (ER), and workdays lost from parents were not significantly different in RVGEs compared to the other viral infections.

Conclusions.

Features of RVGE in terms of hospitalisation length and indirect cost are lower than those reported in previous studies.

Results of the present study reflect the large variability of data present in the literature.

This observation underlines the utility of primary care networks for AGE surveillance and further studies on community-acquired gastroenteritis in children.
