Colds & Flu Overview
Colds and influenza (the flu) are both respiratory infections that affect the nose, throat, and lungs—but they’re caused by different viruses. Colds usually develop gradually and are milder; the flu tends to start suddenly and can be more severe. Both spread easily, especially in fall and winter.
What Are Colds and the Flu?
The common cold is typically mild and gradual in onset. The flu often begins abruptly with more intense symptoms. Both are contagious and can spread person to person via droplets and contaminated surfaces.
Common Symptoms
Cold Symptoms
- Stuffy or runny nose
- Sneezing and sore throat
- Mild cough or chest discomfort
- Fatigue or low energy
- Low-grade fever (or none)
Flu Symptoms
- Sudden fever, chills, and body aches
- Headache and marked exhaustion
- Dry cough and sore throat
- Nasal congestion or runny nose
- Occasionally nausea or vomiting (more common in children)
If symptoms start suddenly and you feel extremely tired or achy, it’s more likely the flu.
What Should I Do If I Think I Have a Cold or the Flu?
- Rest and stay well hydrated (water, herbal tea, broths).
- Use a humidifier or saline sprays to soothe dry airways.
- Gargle warm salt water for sore throats.
- Consider over-the-counter remedies for congestion, cough, or fever.
Call your healthcare provider if you experience:
- High fever lasting more than 3 days
- Shortness of breath or chest pain
- Severe fatigue or confusion
- Persistent vomiting or signs of dehydration
- Symptoms that improve but then return or worsen
How Are Colds and the Flu Treated?
- Colds: Caused by viruses—antibiotics don’t help. Focus on comfort and rest.
- Flu: Antiviral medications may shorten illness if started within 48 hours of onset. Your provider will guide you based on risk factors and health status.
Most people recover in 7–10 days; fatigue after the flu can linger a bit longer.
How to Prevent Colds and Flu
- Wash hands often with soap and water.
- Avoid touching your eyes, nose, and mouth.
- Stay home when you’re sick to prevent spread.
- Support immunity with nutrient-dense foods, regular movement, good sleep, and stress management.
- Get an annual flu vaccine—the best defense against severe illness.
