Flu, COVID-19, or a Cold?
Understanding the Symptoms and Knowing When to Seek Care
When you start feeling under the weather, it’s natural to wonder—do I have a cold, the flu, or COVID-19?
These illnesses share many symptoms but are caused by different viruses and vary in severity. Knowing the difference can help you take the right steps to recover and prevent spreading illness to others.
Key Differences
Colds are usually milder and cause sneezing, congestion, and sore throat.
Flu symptoms tend to be more intense, with sudden onset fever, body aches, and extreme fatigue.
COVID-19 shares many flu-like symptoms but often includes loss of taste or smell and can lead to breathing difficulties.
Could It Be Allergies?
If your symptoms last for weeks, and include sneezing, itchy eyes, or a runny nose, but no fever or body aches then allergies may be the cause.
Unlike colds, flu, or COVID-19, allergies aren’t caused by a virus.
