Every year, millions of Americans struggle to tell the difference between a common cold and the flu. While both are respiratory illnesses, the flu can lead to serious complications if left untreated. Here's how to tell them apart — and when to seek care.

Common Cold Symptoms

A cold usually comes on gradually and is milder: - Runny or stuffy nose - Sneezing - Mild cough - Sore throat - Low-grade or no fever - General fatigue

Colds typically resolve on their own within 7-10 days with rest and fluids.

Flu Symptoms

The flu hits harder and faster: - Sudden onset of high fever (100-104°F) - Severe body aches and muscle pain - Intense fatigue and weakness - Dry, persistent cough - Headache - Chills and sweats

When to See a Doctor

Schedule a telehealth visit if you experience: - Fever over 101°F lasting more than 3 days - Difficulty breathing or shortness of breath - Chest pain or pressure - Severe dehydration (dizziness, dark urine, no tears) - Symptoms that improve then worsen (could indicate secondary infection) - You're in a high-risk group: pregnant, over 65, have diabetes, asthma, or a weakened immune system
