Background: Acute gastroenteritis (AGE) is still one of the leading causes of hospitalisation and is regarded as having the second-highest burden of all infectious diseases. Understanding the microbiological cause of diarrhoea and how it relates to how long a patient stays in the hospital is crucial for the adoption of effective public health policies to reduce these diseases and, in many circumstances, for the right treatment. Objective: To investigate the epidemiology, clinical, and operational characteristics of AGE in hospitalized children in a tertiary pediatriccenter in Raipur, India. Methods: In this retrospective study we evaluated the 1120 paediatric patients who were admitted to the treatment of AGE between February 2021 and January 2023 and were younger than 14 years. We identified the microbial (causative agent), clinical (major symptoms) and functional aspects (Length of hospitalization) of gastroenteritis. Results: Mean age of the patients admitted for AGE was 9.5 years. Majority of patients were from the age group of 0 to 2 years old (55.5%). Vomiting and diarrhoea were the most frequent AGE symptoms. Microbial characterization report showed 172 samples with positive microbial growth. Out of 172 instances, 59 (34.3%) had bacterial pathogens, 110 (64%) had viral pathogens, 3 (1.7%) had protozoa. Salmonella was the most frequent bacteria and rotavirus was common causative virus for AGE. Length of hospitalization was more in viral AGE than bacterial one and it was also highest in 0-2 years age group and lowest in 10-14 years age group. Conclusion: According to this study, rotaviruses and Salmonella species were the most prevalent AGE pathogens in paediatric hospital patients. Although it was longer in viral AGE, the gender and age of children with AGE did not affect how long they stayed in the hospital.
