Symptoms of rotavirus â the leading cause of viral gastroenteritis in infants and young children â usually appear one to three days after exposure. But you're contagious even before you develop symptoms, and up to two weeks after you've recovered.
A person infected with a cold virus may be contagious for two to three days before any symptoms appear and remain so until he or she doesn't show any symptoms. This is a period of up to two weeks or so. The height of the common cold contagious period is when symptoms are at their worst -- usually around day 2 to day 4 of the cold.
