Colds and flu are both viral infections, and both are common in the colder months. They share some symptoms, but flu is usually more severe.

Typical differences

	Cold	Flu
Start	Gradual	Often sudden
Fever	Rare or mild	Common, can be high
Aches	Mild	Often strong body aches
Tiredness	Mild	Can be extreme
Runny or stuffy nose	Very common	Sometimes
Sneezing, sore throat	Common	Sometimes

Self-care for both

Rest and keep warm.
Drink plenty of fluids.
Over-the-counter remedies can ease symptoms — follow the label or ask a pharmacist.
Stay home to avoid spreading it.

PreventionWash hands often, cover coughs and sneezes, and ask about the annual flu vaccine if you're eligible.

When to get medical help

Contact a doctor if symptoms are severe, last longer than expected, or get worse after improving. Seek urgent help for difficulty breathing, chest pain, confusion, or signs of dehydration. Older adults, pregnant people, young children and people with long-term conditions should be especially careful.
