How Long Does Flu Really Last?

How long does flu really last?

Flu timelines are not always simple.

Day 1 can hit fast with fever, chills, body aches, cough, headache, and exhaustion.
Days 2–3 can feel like the peak fight.
By Day 4–5, some people start turning the corner.
After one week, many healthy people feel better — but not always fully normal.
The cough and fatigue can last longer than the fever.

Flu can also spread before symptoms and for several days after getting sick, especially early on.

If breathing becomes hard, chest pain appears, confusion happens, dehydration is severe, symptoms worsen again, or you are at higher risk, get medical advice.

The flu fades in phases:

Fever first.
Energy later.
Cough last.
