Molecular epidemiology of rotaviruses in the south-east Asian region from 2009 to 2015

Abstract Background In Asia, rotavirus accounts for approximately 45% of admissions due to acute gastroenteritis in children Methods Stool samples collected from children Result: Of the 2354 EIA positive samples tested, G12P[8] (36.8%), G1P[8] (30.1%), and G12P[6] (41.3%) were the most common strains isolated from Myanmar, Sri Lanka, and Nepal respectively. Conclusion There was substantial diversity of rotavirus genotypes, and continued surveillance in developing countries of Asia will help in understanding the epidemiology of rotavirus before and after introduction of vaccines.
