Objective: To investigate the viral etiology, through the use of molecular methods, of acute gastroenteritis (AGE), which is a considerable public health burden in Native American infants. Study design: From March 2002 through February 2004, AGE and non-diarrheal stools were collected from Navajo and White Mountain Apache infants who received placebo during a rotavirus vaccine trial. Case (n = 247) and control (n = 344) specimens were tested for enteric adenovirus, astrovirus, norovirus, rotavirus, and sapovirus with real-time polymerase chain reaction. The odds of AGE were compared with population-averaged logistic regression models. Results: In 65% of the cases of AGE (161/247), at least one virus was detected; norovirus (n = 80, 32%) and rotavirus (n = 70, 28%) were the most common. A virus was detected in 38% of control specimens (132/344). Detection of "any virus" was associated with AGE (OR = 3.22; 95% CI, 2.11-4.91), as was detection of norovirus (OR = 2.00; 95% CI, 1.22-3.26) and rotavirus (OR = 2.69; 95% CI, 1.52-4.79). Conclusion: This study highlights the significant burden of viral AGE in American Indian infants and identifies pathogen targets for future prevention efforts in this population.
