Rotavirus primarily spreads among individuals through the fecal-oral route. This transmission method occurs when infected fecal matter contaminates food or water, which is then ingested by another person. The virus can survive outside the body for an extended period, making it resilient in various environments, particularly in settings with poor sanitation.

Children are particularly susceptible to rotavirus, often spreading it in day-care centers or family settings where close contact occurs and hygiene practices may be lax. The fecal-oral route is effective in propagating the virus because large amounts of the virus are excreted in the stool of infected individuals, which can easily contaminate surfaces, hands, or food if proper handwashing and sanitation practices are not followed.

Other routes of transmission, such as airborne droplets or vectors, do not apply to rotavirus, as it is not transmitted through respiratory means or animal bites. Direct contact with infected wounds is also not relevant to the transmission of rotavirus, which is not associated with blood or skin infection transmission. Thus, recognizing the fecal-oral route as the primary mode of transmission highlights the importance of hygiene and sanitation in preventing the spread of this virus.
