Human rotavirus samples from 54 children with acute gastroenteritis in Myanmar in 2011 were subjected to reverse transcription-PCR to determine their G and P types. On G typing, G2 (24/54; 44.4%) was found to be the most prevalent, followed by G12 (17/54; 31.5%) and G1 (1/54; 1.9%). Mixed cases with G2 and G12 were found in 12 of the 54 (22.2%) samples. On P typing, P was found to be the most predominant (29/54; 53.7%), followed by P (17/54; 31.5%) and P (4/54; 7.4%). Mixed cases with P and P were detected in 4 of 54 (7.4%) samples. Thus, occurrence of G2 and unusual G12 in high proportions was characteristic of human rotaviruses in Myanmar in this study setting.
