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.
Most experts agree that adults with a cold or the flu start being contagious about a day before they start experiencing symptoms. For the flu, the contagious period then lasts five to seven days into the illness.f you think about how a virus works, it makes sense that we're most contagious when our symptoms are at their worst. Viruses like influenza and those that cause the common cold (there are a couple of hundred of them) have an incubation period once they get into your body.
