The difference is how fast it arrives
A cold creeps up. Flu knocks you over in an afternoon.
Sore throat first, then the rest
Fever and aches, almost at once
Fever
Rare with a cold. Usual with flu, and often high.
Aching
Mild with a cold. With flu it is the main event.
Tiredness
A cold slows you down. Flu stops you.
How long
A cold, about a week. Flu, two — and the tiredness longer.
