Life-threatening virus that causes vomiting and diarrhea at high levels in the U.S., CDC says

April 16, 2026 - 02:59

The Centers for Disease Control and Prevention (CDC) reports that detections of rotavirus, a common and potentially life-threatening stomach virus, are currently at high levels nationwide. This highly contagious pathogen causes severe gastroenteritis, leading to intense vomiting, diarrhea, fever, and abdominal pain.

While rotavirus can infect individuals of any age, it poses a particularly severe risk to infants and young children. The rapid dehydration caused by the illness is a primary danger and a major cause of emergency room visits and hospitalizations in this vulnerable group.

Medical experts are expressing heightened concern as these high virus levels coincide with a noted decline in childhood vaccination rates. The rotavirus vaccine, administered in early infancy, is highly effective at preventing severe illness. Public health officials warn that lower immunization coverage could directly result in more children suffering severe complications, increasing the strain on healthcare systems.

Parents and caregivers are urged to ensure children are up to date on vaccinations and to practice rigorous hygiene, including frequent handwashing, as the virus spreads easily. Symptoms require close monitoring, and medical attention should be sought if signs of dehydration, such as decreased urination, lethargy, or crying without tears, appear in a sick child.
