Abstract
Google-based Internet query share (IQS) for rotavirus search terms correlated well with US rotavirus laboratory detections from 2004 to 2010 (r = 0.88; P < .001), capturing the reduction observed during postvaccine years (2008-2010). IQS analysis could become an inexpensive and reliable supplement for monitoring the impact of rotavirus vaccination in the United States.
