The contagious period for a cold lasts about three to four days into the illness. As a general rule, people with a cold are most contagious about three days after their initial exposure to the virus.For more information on colds, influenza and related topics, check out the links on the next page.Print.n fact, many of us are completely wrong. If 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.
Flu Contagious Period. Flu starts being contagious about 24 hours before you have symptoms. You're most contagious when you first get sick and for the following 2 to 3 days. The severity of your symptoms correlates to how many new viruses are being produced, so you're less contagious as you start to feel better. Most people stop being infectious approximately 5 to 7 days after getting sick, but you can remain contagious for as long as 10 days. Limiting Flu Spread To limit the spread of flu, the Centers for Disease Control and Prevention recommends staying home while you're sick and for at least 24 hours after your fever breaks.
