Protecting your children against Rotavirus with cases rising across the nation
PADUCAH, KY (May 22, 2026) — Rotavirus, a highly contagious virus that can cause severe vomiting and diarrhea in infants and young children, is on the rise across parts of the United States.
Recent data from the Centers for Disease Control and Prevention (CDC) shows an increase in rotavirus infections since January, with some of the highest activity reported in the Midwest.
“Rotavirus can make young children very sick very quickly,” said Heath Morgan Cates, MD, Baptist Health Medical Group Pediatrics. “The virus itself usually resolves on its own, but the risk of dehydration is what often leads families to seek emergency care. Recognizing symptoms early and acting quickly is essential.”
Rotavirus spreads easily through contact with contaminated surfaces and then touching the mouth. Symptoms typically begin about two days after exposure and may include fever, abdominal pain, repeated vomiting, loss of appetite and severe watery diarrhea. While most children recover within several days, dehydration is the most serious and common complication, especially in children under the age of five.
The CDC estimates that rotavirus vaccines prevent 40,000 to 50,000 hospitalizations annually. Studies show that 9 out of 10 vaccinated children are protected against severe disease, and 7 out of 10 are protected from infection altogether. The vaccine is given orally starting at two months of age, with two or three doses depending on the vaccine type. Dr. Cates warns that declining vaccination rates, combined with rising case numbers, could lead to more severe illness and increased hospitalizations.
“The majority of children we see hospitalized with rotavirus are either too young to be fully vaccinated, haven’t completed the vaccine series or are unvaccinated,” said Dr. Cates. “Staying on schedule with childhood vaccines remains the most effective way to protect children from severe illness.”
In addition to vaccination, parents and caregivers can help limit the spread of rotavirus by encouraging frequent handwashing with soap and water, disinfecting commonly touched surfaces and keeping sick children home from school or daycare. There is no specific antiviral treatment for rotavirus, so care is focused on supportive measures such as maintaining hydration with electrolyte fluids, offering small and frequent feedings, and managing fever.
Parents should seek medical care if a child shows signs of dehydration, including dry mouth, few or no tears, decreased urination, unusual sleepiness, persistent vomiting, high fever, bloody stools or worsening symptoms.
“Rotavirus is serious, but it’s also largely preventable,” said Dr. Cates. “Vaccinating early, watching for symptoms and knowing when to seek care can make all the difference.”
