The burden of rotavirus disease in the Latin American region has been poorly understood despite the promise of effective vaccines. We describe here the implementation and results of a rotavirus surveillance network in the Latin American and Caribbean region. From 2005 through 2007, stool specimens and epidemiologic information were gathered from children 75% of strains, although unusual strains, including G12, were detected at low levels. As rotavirus vaccines continue to be introduced in Latin America, maintenance of surveillance will provide robust pre-introduction data and a platform for estimating vaccine effectiveness and other measures of impact.
