The flu, (depending upon the strain of virus), can appear between 1 to 4 days after the virus enters the body. So it presents faster and harder than a cold. Rather than starting with nose or throat, it usually begins with a strong headache, body aches, painful to swallow, exhaustion and a high fever with chills.
If you have been exposed to someone with the flu, you may be concerned about catching it. You may also wonder how long it takes to get sick after you have been exposed and how long you are contagious when you have it. Flu Incubation Period The typical flu incubation periodâthe time between exposure and the start of symptomsâis between 24 hours and four days, with the average being two days. This means that if you are exposed to the influenza virus and become infected, you will start to experience flu symptoms anywhere between 24 hours and four days after the exposure. Another factor that contributes to how the flu spreads is when exactly you may be contagious.
