Burden of rotavirus gastroenteritis (RVGE) in outpatient setting in India is not fully understood. A prospective study was undertaken to describe RVGE among Indian children less than 5 years of age presenting in outpatient departments with acute gastroenteritis (AGE). This study was conducted at 11 outpatient departments (OPDs) of private pediatric clinics in urban areas of India. A total of 605 eligible children were enrolled at OPDs. Stool samples of the subjects were collected and tested for

Physician examined the children and documented the disease particulars. In addition, parents/guardians were interviewed for AGE related symptoms, health care utilization and cost incurred due to AGE, and parental stress associated with AGE. After OPD, parents/guardians completed diary cards and questionnaires to capture the information for 14 days following the enrollment. Complete data for analysis including stool sample results was available from 552 subjects. 23% (127/552; [CI 19.5, 26.5]) of stool samples were rotavirus (RV) positive. RT-PCR was done for 85.8% (109/127) of RV positive samples. G1, G2, G9, and G12 types were identified in 34.9% (38/109), 37.6% (41/109), 8.3% (9/109), and 6.4% (7/109) stool samples, respectively. P[4] and P[8] were identified in 36.7% (40/109) stool samples each, followed by P[6] identified in 15.6% (17/109) stool samples. At the time of enrollment, all three symptoms (vomiting, diarrhea, and fever) were observed concurrently in higher proportion of RV positive subjects compared to RV negative subjects (60.6% [77/127] vs. 42.8% [182/425], p = 0.0004). Healthcare resource utilization, costs incurred due to disease, and parental stress were higher for RV positive subjects compared to RV negative subjects. In conclusion, RVGE was found to be a definite burden in AGE cases attending pediatric outpatient clinics in urban areas and it was associated with substantial economic and psychological burden. Introduction of rotavirus vaccine in India may help in reducing this disease burden.
