During 3 years surveillance (January 2001 through December 2003) for acute gastroenteritis in human in Daejeon region, 432 out of 4,869 stool samples were selected as rotavirus-positive specimens by means of antigen-capture enzyme-linked immunosorbent assay (ELISA). The P (VP4) and G (VP7) genotypes for 432 stool samples were investigated by reverse transcription polymerase chain reaction (RT-PCR) and nested multiplex PCR. The most prevalent P subtype was P[8] (44.9%), followed by P[4] (25.7%) and P[6] (17.1%). No cases for P[10] and P[9] subtypes were found through the study. In G subtyping, G1 (53.2%) was the most frequently found G type, followed by G2 (23.1%), G3 (9.5%), G4 (6.7%), and G9 (0.9%). The order of detection rates for G2, G3 and G4 was variable by years. The most common G- and P- type combination found in this study was G1P[8] (33.1%), followed by G2P[4] (20.4%), G1P[6] (10.0%), G3P[8] (7.2%) and G4P[6] (4.2%). The mixed types of G and P were observed most frequently in P[8] (1.4%) and G1 (3.2%), respectively. This is the first molecular epidemiological study for Group A rotavirus in Daejeon region. The results might be useful data for evaluating the epidemiological status of rotaviral diarrhea in the region
