COVID-19, flu, strep or common cold? How to tell the difference-featured-image

With cold and flu season approaching, you might be anxious about what will happen if someone in your family gets sick. At the first sign of sniffles, you’re likely to wonder: “Do I have COVID-19? Or could it just be a common cold? Maybe the flu? And what do I do about it?”

It’s not always easy to tell, but with First Stop Health Virtual Urgent Care from your employer, you can get diagnosis and treatment via phone or video 24/7. Our doctors call back in 7 minutes (on average) to make sense of your symptoms and help you feel better, faster.

In the meantime, here’s what you should know about telling apart COVID-19, the flu, strep and common cold.

 

Symptoms

Understanding the cause of your upper respiratory symptoms can be a challenge. Not all patients with the same illness experience the same symptoms, and there’s also a good deal of overlap:

  • Cold symptoms include stuffy nose, congestion and sneezing.
  • Strep throat symptoms include white spots on your tonsils, swollen lymph nodes in your neck, fever, and lack of cough.
  • Flu symptoms include fever, chills, body aches, sore throat and headache.
  • COVID-19 shares a lot of symptoms with the flu, but loss of smell and taste are specific to COVID-19.

 

Treatment

For COVID-19, the flu, strep throat, and the common cold, most patients simply need increased fluid intake, rest, fever-reducers (not aspirin!) and pain relievers. Other treatments include:

  • antiviral medications to shorten the course of (or even prevent) the flu.
  • antibiotics to treat strep throat (but not COVID-19, the common cold or other viral illnesses).
  • prescription cough medication (and even inhalers) if your diagnosis is bronchitis or asthma.
  • monoclonal antibodies (by IV infusion) for COVID-19 may be of value to patients at high risk of complications. Unproven treatments (like ivermectin and hydroxychloroquine) are NOT advisable.
  • over-the-counter medications and home remedies.

9 in 10 First Stop Health patients avoid an in-person visit. In rare cases, your doctor might recommend that you seek in-person care at the doctor’s office, hospital or emergency room.
