When sniffles, coughs, fatigue, or congestion hit, it can be difficult to know whether you are dealing with the flu, COVID-19, or seasonal allergies. At Three Rivers Medical Associates, we help patients every day who are unsure what their symptoms mean or how to treat them.
Whether you woke up with a sudden fever or you are battling an itchy throat that will not go away, our team is here to provide clarity and the right care from the start.
Flu vs COVID vs Allergies: Understanding the Key Differences
Although these conditions often share similar symptoms, they develop differently and have unique patterns that help us identify the cause.
Flu symptomsusually appear very suddenly. Patients often report a high fever, chills, deep muscle aches, severe fatigue, headache, and a dry cough or sore throat. Many describe it as feeling like they were hit by a truck, which is one of the classic indicators of influenza.
COVID-19 symptomsremain broad and can vary from person to person. Fever, chills, a new or persistent cough, fatigue, shortness of breath, and changes in taste or smell are still common presentations. Congestion, sore throat, or body aches can resemble the flu or allergies, which is why an experienced evaluation is so important.
Allergy symptomsfollow a more predictable pattern. Sneezing, itchy or watery eyes, a runny or stuffy nose with clear mucus, and an itchy throat or ears are typical markers of allergies.
Allergies rarely cause fever, and symptoms often continue as long as you are exposed to pollen, dust, or another trigger.
How Our Doctors Diagnose Flu, COVID, and Allergies
When you visit Three Rivers Medical Associates, we begin with a thorough conversation about your symptoms, how they started, how quickly they progressed, and how they are affecting your daily activities. We also review your medical history and recent exposures. If you typically deal with allergies at certain times of the year or were recently around someone who tested positive for the flu or COVID-19, those details help guide our diagnosis.
COVID Testing, Flu Testing, and Allergy Testing in Columbia, SC
If your symptoms overlap too much for a clear answer based on conversation alone, diagnostic testing helps us accurately determine what is causing your illness.
We offer:
- Rapid and PCR COVID-19 testing
- Fast and accurate flu testing
- Referrals for allergy blood testing or skin testing for patients with ongoing or seasonal symptoms
These tools allow us to give you answers quickly so your treatment plan does not get delayed.
Personalized Treatment Plans for Flu, COVID-19, and Allergies
Once we identify the cause of your symptoms, we design a treatment plan tailored to your needs.
For flu, early antiviral medication can shorten the illness and reduce severity. Rest, hydration, and supportive care remain important for recovery.
For COVID-19, we determine whether antiviral treatment is appropriate, provide guidance on home monitoring, and check in as needed. For mild or moderate cases, we focus on proven strategies that help you recover safely at home.
For allergies, we recommend fast-acting relief options such as antihistamines, nasal sprays, or decongestants. When allergies become long-term or interfere with daily life, we discuss ongoing management strategies, including immunotherapy.

Frequently Asked Questions
How can I tell if I have the flu or COVID-19?
Flu symptoms often begin suddenly with fever and severe body aches. COVID-19 can present similarly but may also include shortness of breath or changes in taste or smell. Testing is the most reliable way to know the difference.
Can allergies cause a fever?
Allergies almost never cause a fever. A fever typically points to an infection such as the flu or COVID-19.
When should I see a doctor for flu or COVID symptoms?
If you have trouble breathing, persistent high fever, chest pain, confusion, or symptoms that worsen over time, contact a physician immediately.
Do you offer COVID testing and flu testing in Columbia, SC?
Yes. Three Rivers Medical Associates provides both rapid and PCR COVID tests, along with fast, reliable flu testing.
When are allergy tests recommended?
