Is It a Cold, Flu, COVID, RSV, or Strep?
You wake up with a sore throat, a stuffy nose, and a tired feeling you can’t shake. Maybe there’s a fever, too, or a cough that kept you up half the night. Is it just a cold? The flu? Something else?
These symptoms can point to several different illnesses, and in the first few days they often look a lot alike. Knowing which is which matters because not all illnesses call for the same treatment.
Below, we’ll walk through how cold, flu, COVID, RSV, and strep compare, and when urgent care testing may help, all from your neighborhood care team at MainStreet.
Common Symptoms That Can Overlap
These illnesses can present in very similar ways, which is why figuring out which is which can be confusing.
These overlapping symptoms can include:
- Fever
- Cough
- Sore throat
- Nausea or upset stomach
- Congestion
- Runny nose
- Fatigue
- Body aches
- Headache
- Ear pain
- Sinus pressure
(It’s especially confusing when you’re not feeling well and just trying to keep your head above water.)
Fortunately, there are a few clues that can help narrow down the list.
Cold Symptoms
Colds tend to come on gradually. Common symptoms include a runny nose, congestion, cough, mild sore throat, and sneezing. You may feel under the weather, but many people can still get through most of their day.
Flu Symptoms
In contrast to the common cold, flu often comes on quickly. Many people describe feeling fine in the morning and completely wiped out by evening.
Symptoms may include fever, chills, body aches, fatigue, headache, cough, and sore throat. Chills and body aches in particular are usually far more pronounced with the flu than with a cold, where they may be mild or absent altogether.
COVID Symptoms
COVID symptoms can vary quite a bit from person to person. They may include fever, cough, congestion, sore throat, fatigue, headache, body aches, or a loss of taste or smell. Symptoms can also shift as new variants circulate.
Some people have mild symptoms, while others feel much sicker, which is why COVID testing can be especially helpful.
RSV Symptoms
A lot of people think RSV mainly affects infants and children, but RSV can affect people of all ages. For many healthy adults, it feels a lot like a cold, but it may be more serious for babies, older adults, and people with certain health conditions.
Symptoms may include cough, runny nose, fever, sneezing, wheezing, decreased appetite, or breathing concerns. If you care for an infant or an older loved one, pay close attention to how they’re breathing.
Strep Symptoms
Strep throat often starts with the obvious: a sudden sore throat that can hurt when you swallow. But it’s usually not just the throat. Other symptoms may include fever, swollen glands, headache, or stomach pain. One helpful clue is a sore throat without much cough.
When Urgent Care Testing May Help
Testing may be helpful when:
- Symptoms overlap and it’s hard to tell what’s causing them (typical during cold and flu season)
- Symptoms are getting worse instead of better
- You’ve had known exposure to flu, COVID, RSV, or strep
- A medical provider recommends it
MainStreet Family Care offers testing when appropriate, and your medical provider will review your symptoms and examine you as part of the visit. Because testing is done on site, results may help your provider recommend next steps during your visit.

It’s a good idea to stop by MainStreet Family Care if your symptoms need a closer look, or if you have symptoms after being around someone with flu, COVID, strep throat, or RSV.
