However, the viruses that cause colds (for example, rhinoviruses) are not the same as those that cause the flu (influenza viruses). Although the typical incubation period for influenza is about one to four days, some adults can be contagious from about one day before onset of symptoms for up to two weeks. Other people who develop complications, such as pneumonia, may extend the contagious period for a week or two. For colds, most individuals become contagious about a day before cold symptoms develop and remain contagious for about five to seven days.
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. What Is a Contagious Cold? 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.
