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 cold and flu season lasts from September until May, but catching a cold has nothing to do with the temperature outside. The reason colds are so contagious has more to do with the amount of time people spend inside in close contact with each other. The common, contagious cold is a brief, mild illness. The early symptoms of headache, sneezing, chills, and sore throat start two to three days after you have been infected. The symptoms of nasal discharge and congestion increase quickly and then go away after about a week.
