SAN DIEGO — Results from a population-based study presented here suggest that population susceptibility to rotavirus may have shifted following the introduction of rotavirus vaccine.
Natasha Halasa, MD, MPH, of Vanderbilt University, and colleagues assessed population-based surveillance data for children aged 14 days to 18 years who presented with acute gastroenteritis to EDs and outpatient clinics in Davidson County between December 2012 and September 2014. The study cohort included 2,221 patients who presented with acute gastroenteritis and 1,094 healthy controls. Researchers assessed stool specimens to determine the proportion of acute gastroenteritis visits due to rotavirus, norovirus, sapovirus and astrovirus during the study period.
