Rotavirus is the most common gastrointestinal pathogen present in day-care settings. Control and prevention of rotavirus infection are difficult because of the lack of a licensed vaccine, the absence of any effective treatment other than palliative measures and the presence of asymptomatic children shedding virus. Rotavirus is transmitted by fecal-oral contact and possibly by contaminated surfaces and hands and respiratory spread. Other gastrointestinal pathogens are also transmitted primarily by the fecal oral route, although contaminated surfaces, hands or food may also serve to transmit infection in some cases. Control and prevention measures for all enteric pathogens include isolating infected children from others, thoroughly cleaning and disinfecting environmental surfaces with effective agents and strictly following handwashing procedures before and after contact with infected persons and/or potentially contaminated surfaces.
