In Our Own Words

Rotavirus is a common contagious viral infection worldwide, causing inflammation of the intestines, loose stools, and diarrhea. It is a common cause of diarrhea in toddlers and young children and before vaccine introduction, outbreaks of severe rotavirus diarrhea were the norm at day care centers and schools every winter in the United States. In austere environments around the world, it takes many lives.

Because diarrhea can be severe, complications from the illness include dehydration, which can be life threatening, especially in very young children. Vaccines are available in order to help prevent severe rotavirus gastroenteritis.
