According to information from the US Centers for Disease Control and Prevention (CDC):
"The typical incubation period for influenza is 1-4 days (average: 2 days). Adults shed influenza virus from the day before symptoms begin through 5-10 days after illness onset. However, the amount of virus shed, and presumably infectivity, decreases rapidly by 3-5 days after onset in an experimental human infection model. Young children also might shed virus several days before illness onset, and children can be infectious for 10 or more days after onset of symptoms. Severely immunocompromised persons can shed virus for weeks or months.
"Uncomplicated influenza illness typically resolves after 3-7 days for the majority of persons, although cough and malaise can persist for >2 weeks. However, influenza virus infections can cause primary influenza viral pneumonia; exacerbate underlying medical conditions (e.g., pulmonary or cardiac disease); lead to secondary bacterial pneumonia, sinusitis, or otitis media; or contribute to co-infections with other viral or bacterial pathogens."

The flu usually lasts for about 2-5 days. The worst part is usually over by the second or third day, and then you have to rest up to regain strength.
The worst parts last 2-5 days though other symptoms can last 2-3 weeks.
Normally, flu symptoms start to improve after two to five days, but it is fairly common for the flu to last beyond a week.
at least a few days
Determining how long a flu may last anywhere from three days to two weeks. As long as there are symptoms present, the flu is still within your system.
how long will weakness and malaise last after the flu
How long does it take from contact with the flu virus to showing symptoms?
Flu symptoms usually last 3 to 7 days, but sometimes up to 10 days. Cough from the flu could last longer than the other symptoms, perhaps up to 2 weeks. If cough continues beyond that time, you should contact your health care professional to be sure you do not have a secondary respiratory infection.
All symptoms of the flu are usually gone in 7 to 10 days, except a cough, which might last up to two weeks. If symptoms are extended beyond this time frame, check with your doctor to see if you need an examination.
A week, Its like the common cold. Though swine fllu is deadly & may last longer.
Yes, when people talk about having bad flu or a bad case of the flu, they just mean it is giving them worse symptoms than usual or than the last flu virus they caught.
The guidelines from the US Centers for Disease Control and Prevention (CDC) are that if you have flu like symptoms you should not go in public or travel until 7 days after the very first symptoms or 24 hours following the last date of symptoms whichever is longer.
Well, I really do recommend buying a Nintendo Wii.
Fever and chills are a result of the flu. With the flu comes symptoms such as fatigue, chills, sweating, and fever. The length of these symptoms last no more than two to three weeks.
The incubation period of bird flu is expected to be 3 to 10 days.
While a flu shot will not be effective against any active flu symptoms it will protect against the other flu strains contain in the shot. Flu symptoms such as high fevers, upper respiratory problems should be controlled but the flu virus in a shot is a 'dead' non-active virus and should not affect or cause any current virus.
