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.
The flu is also contagious the day before the first symptoms begin. The person remains contagious for 5 to 7 days, as long as the body is producing new mucus, and they are also contagious as long as they have a fever.
