Rotavirus is contagious and the infection is usually spread from person to person, through the fecal-oral route. Fecal-oral transmission occurs when bacteria or viruses found in the stool of one person are swallowed by another person. This can occur when small amounts of fecal matter may be found on surfaces such as toys, books, clothing, etc. and on the hands of parents or child-care providers; but are usually invisible. Rotavirus may also be transmitted through intake of fecally-contaminated water or food or by respiratory droplets that people sneeze, cough, drip, or exhale. Rates of the illness among children in developed and less developed countries are similar.
