It varies from person to person. For adults, one day before the flu symptoms occur and a week after you become sick.
You can begin being contagious even one or two days beforeyou know you have the flu, while you have symptoms - which usually last 7 - 10 days. The rule of thumb is that you are no longer contagious after you go for a full 24 hours without a fever while taking no fever reducing medication.

The typical incubation period is 1 to 4 days, but this will vary from person to person and the specific strain of flu compared to a different strain of the flu.

More on duration of flu symptoms according to the Centers for Disease Control and Prevention:

"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 coinfections with other viral or bacterial pathogens."

Do flu shots contain live bacteria?

No, there is no live bacteria in flu shots. Flu shots are to prevent the flu which is caused by a virus, not bacteria. The various flu vaccines contain pieces of viruses that are treated to be able to give you immunization, but not make you sick from the virus contained in the vaccination. The flu shots contain inert ("dead") viruses or pieces of viruses instead of whole particles. The flu mist used in the nasal vaccination is made with active ("live") but weakened viruses that can not make you sick if you have an otherwise healthy body and immune system.

Why are flu vaccinations produced from dead virus and not live viruses?

In the US there is a flu vaccination made with live viruses that have been weakened (attenuated) to prevent them from making otherwise healthy people sick. This type of vaccine can be used by those who are healthy and aged 2 - 49. It creates a very good immune response to cause immunity and so it can be administered in an intranasal mist that is inhaled into the nose instead of having to be given in a shot. The vaccines for flu that are made to be injected in a shot are made from "dead" viruses or pieces of dead viruses. So flu vaccinations are produced from both "dead" viruses and live viruses.


Are the microbes that are injected in a vaccination dead or alive?

They can be either. Some vaccines are made with dead viruses or particles of viruses and other vaccines are made with attenuated (weakened) viruses that are not able to make an otherwise healthy person sick. In 2009 the swine flu vaccine approved for use in the US was prepared both ways, the nasal flu vaccine was made from attenuated viruses and the shots were made with dead viruses.
