  • Rotavirus – across the world, this is the most common cause of viral gastroenteritis in a child, it can cause high levels of infection because they can put their hands and fingers in areas that are contaminated with the virus into their mouths. The disease is most severe in fats and young children. Adults infected with rotavirus may not exhibit symptoms., yet still, can spread the illness, this is much more concern in institutional settings because infected adults unknowingly can pass the virus to others.
