Abstract : Hospital-based, prospective, active surveillance for rotavirus gastroenteritis (RVGE) was conducted to determine the proportion of rotavirus infection among acute gastroenteritis (AGE) cases and to identify rotavirus strains thereby providing information on epidemiology and strain diversity of RVGE. Stool samples were collected from children <5 years old admitted to Yangon Children’s Hospital (YCH) for AGE during January 2015 to September 2017, screened for rotavirus antigen by ELISA (ProSpecTTM Rotavirus) and genotyped by reverse transcription polymerase chain reaction. Overall, 1167/2393 (49%) of samples tested positive for rotavirus, ranging from 46-53% each year. The most affected was the 6-23 months age group, 956/1167 (81.9%) followed by 0-5 months 106/1860 (9.1 %) and 24-59 months 105/1167 (9.0%). RVGE occurred in a seasonal cycle with peak detection in the cold and dry months (November to February). As compared with non-RVGE, RVGE cases had significant higher percentage of vomiting (84.5% Vs 73%; P<0.05), fever (80.1% Vs 71.8%; P<0.05) and severe clinical scoring (79.3% Vs. 67.6%; P<0.05). Genotyping revealed that G9P[8] was predominant in the year 2015 (53.3%) and 2016 (30.9%), however, it was replaced in 2017 by G3P[8] (58.2%). Because of the high morbidity of RVGE, rotavirus vaccine is planning to introduce in Myanmar in the future, information from this surveillance not only highlights facts for consideration of target population, issues of dose scheduling and selection of appropriate vaccines in pre-vaccination era but also provide vital baseline data for post-vaccination monitoring of vaccine impact and effectiveness.
