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.
With some viruses, you're contagious for as long as you have symptoms or even beyond. With others, you continue to have symptoms after youâre no longer contagious. Adults who have the flu are contagious for five days after first developing symptoms, while kids can stay contagious even longer. If you have a cold, you're most likely to give it to someone else during the first few days of having a runny nose, sneezing, and coughing.
