The typical incubation period for influenza is 1â4 days (average: 2 days). Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.mong generally healthy older adolescents and adults living in areas with confirmed influenza virus circulation, estimates of the positive predictive value of a simple clinical definition of influenza (acute onset of cough and fever) for laboratory-confirmed influenza infection have varied (range: 79%â88%).
The time between the exposure to the virus and the symptoms to appear is called the incubation period. The normal incubation period for flu is about 3-5 days. After the incubation period, you start displaying symptoms and excreting enough viruses to infect people around you. It will start with a mild headache, but the next day, you will have a few aches with a low fever. It will turn into a high fever on the third day with a runny nose.
