Abstract

Objective: To determine the clinical and epidemiological profile and circulating strains of rotavirus among children less than 5 y of age hospitalized for diarrhea in a tertiary care center of western Rajasthan.

Method: Children < 5 y of age admitted for acute gastroenteritis were recruited in this hospital-based surveillance study. Detailed clinical history and sociodemographic information was collected for all enrolled children. Severity of the gastroenteritis was assessed using the 20-point Vesikari Clinical Severity Scoring System. Rotavirus positivity was tested in the stool samples collected from children by commercially available techniques and further molecular characterization done as per defined protocol.

Results: Out of 1055 enrolled children, overall positivity rate of typable rotavirus was 18.95% (169/892). Among children who were less than 24 mo of age, positivity due to rotavirus diarrhea was maximum (24.4%). Distinct seasonality was observed as maximum cases of rotavirus diarrhea were detected in the months of December to February. Commonest G type was G3 (54%) followed by G1 (19%) while predominant P type was P[8] (77%) followed by P[4] (11%). G3P[8] (51.83%) was the commonest genotype observed in the study region.

Conclusion: The current study found positivity of rotavirus to be 18.95% among children aged 0-59 mo admitted due to acute gastroenteritis is a tertiary care setting in northern part of India. Emergence of newer predominant strains emphasizes the need of continued surveillance to determine the changing trends.
