Understanding the Flu vs. COVID-19: Symptoms, Testing, and When to Visit Urgent Care in Greeley


Flu season and COVID-19 continue to overlap, and the symptoms can feel nearly identical. So how do you know what you're dealing with—and when is it time to get tested or seek treatment?


At Nadora Urgent Care in Greeley, we’re here to help you sort through the confusion and get the care you need, fast.


Shared Symptoms: What Makes Flu and COVID-19 Seem So Similar?

Both viruses can cause:

  • Fever or chills

  • Body aches

  • Fatigue

  • Cough

  • Headache

  • Sore throat

  • Runny or stuffy nose

Because the symptoms are so similar, Urgent Care in Greeley often recommends testing to confirm which illness you have.


Key Differences in Symptoms

While flu and COVID-19 share a lot of overlap, there are some key differences:

  • COVID-19 is more likely to cause loss of taste or smell, and can lead to longer-lasting symptoms.

  • The flu tends to come on more suddenly, while COVID symptoms may develop more gradually.

If you’ve been exposed to someone who tested positive for COVID-19 or flu, early testing and symptom tracking are important.


When to Visit Nadora Urgent Care in Greeley

You should visit Nadora Urgent Care in Greeley if:

  • You have flu-like or COVID-like symptoms and want to be tested

  • You’re having trouble breathing or your symptoms are rapidly getting worse

  • You need clearance for school, work, or travel

  • You have underlying health conditions and want to be proactive

We offer rapid flu and COVID testing with same-day results in many cases.


Treatment Options

Both illnesses typically require rest, fluids, and over-the-counter medications for symptom relief. However, if caught early, antiviral medications may be available—especially for the flu. COVID-19 may also require isolation protocols or monitoring depending on your risk level.
