Background/Objectives: Viral gastroenteritis leads to a broad range of hospitalization costs globally in children, depending on the region. To our knowledge, no recent studies have examined the hospitalization cost associated with viral gastroenteritis in Romania. The aim of this study is to determine the direct hospitalization cost of community-acquired viral gastroenteritis (rotavirus, adenovirus and norovirus) in children admitted to Children’s Clinical Hospital of Brașov, Romania, for one year. Methods: All children aged 0–60 months hospitalized for a stool sample positive for rotavirus, adenovirus or norovirus during January 2023 and December 2023 were included in this study. Hospital-acquired gastroenteritis, gastrointestinal coinfections or children with acute coinfection were excluded. The stool specimens were tested using the immunochromatography method. Results: Out of the total of 282 children, 218 children presented rotavirus gastroenteritis, 35 children presented adenovirus gastroenteritis and 29 children presented norovirus gastroenteritis. Regarding patient characteristics, a higher proportion of boys than girls was observed in all three comparison groups, the average age for children with rotavirus was 22.2 months vs. norovirus and adenovirus, and children presented an average age of 16.4 months. Average hospitalization length of stay for rotavirus was 4.64 (±1.95) days, for adenovirus it was 4.54 (±1.52) days and for norovirus it was 4.75 (±1.93) days. Direct hospitalization costs did not differ between rotavirus, adenovirus, and norovirus infections (Kruskal–Wallis H(2) = 0.145, p = 0.930). Conclusions: In this single-center study, rotavirus remained the most frequent cause of viral gastroenteritis requiring hospitalization in young children, followed by adenovirus and norovirus. Although the average length of stay was similar across groups, hospitalization costs varied, with rotavirus-associated cases showing the highest mean expenses and widest cost variability.
