Each year around September, advertisements for the flu shot pop up at your doctor’s office, pharmacies, and local healthcare clinics. Do you need a flu shot? How do you know you have the flu, anyway, and how long does it take to develop symptoms after you are infected?
Before you get sick, you likely have noticed that there are a few days beforehand during which you may feel unwell but not necessarily sick. Or you may feel nothing at all. This is called the incubation period.
