Infants and toddlers are at the highest risk of developing rotavirus, which can result in dangerous dehydration and hospitalization. The Centers for Disease Control and Prevention has reported a steady increase in rotovirus rates since January. The most recent data shows 20.04 percent of Rotovirus tests came back positive for the week ending April 11 in the Midwest, nearly triple the positivity rate from February. Data from Wastewater Scan, a cooperative effort between Stanford University and Emory University, also indicates that rotav virus rates are increasing in the West and the Midwestern states. However, vaccination rates have decreased in recent years, with only 74 percent of U.S. children being vaccinated against rotavovirus by 8 months of age.
