What Is Rotavirus?

The Leading Cause of Severe and Deadly Diarrheal Disease

Rotavirus is a virus that causes gastroenteritis, an inflammation of the stomach and intestines. Rotavirus is the #1 cause of diarrhea in infants (0-11 months)1,2.

  • Rotavirus primarily infects the small intestine, destroying the surface tissue and preventing the absorption of nutrients, causing diarrhea3.
  • Typical symptoms can range from mild, watery diarrhea to severe diarrhea with vomiting and fever.


Rotavirus is 1 of several pathogens causing the majority of moderate-to-severe diarrhea in children under age 5.





Rotavirus particles (CDC)

  • Rotavirus is commonly spread from person-to-person.
  • It is highly contagious and passes easily through the fecal-oral route by way of contact with contaminated hands or objects, such as toys and surfaces, or through tainted food or water4-9.
  • The virus is incredibly resilient and can live on hands for hours and surfaces for days.
  • Interventions that prevent other forms of diarrhea—such as improvements in hygiene, sanitation and drinking water—do not adequately prevent the spread of rotavirus.
