How do Covid-19 Symptoms Differ from Those Caused by Seasonal Allergies, Colds, and the Flu?

It can be nerve-wracking to know there’s a new kind of bug going around, and we’re not exactly sure how it’s spread. Every sneeze, tickle in the throat, or muscle ache can make you wonder, “Do I have coronavirus?” 

The medical teams at Regional Allergy, Asthma & Immunology Center with offices in Kingsport and Johnson City, Tennessee; and Abingdon, Virginia, are committed to serving the local community. We’ve prepared this brief on COVID-19 using information from the latest authoritative sources, to help you discern your symptoms and understand what is and is not a cause for alarm.

Top COVID-19 symptoms

According to the World Health Organization (WHO), while not all people will present in exactly the same way, there are a few key symptoms that appear in most patients infected with the coronavirus.

Some patients may cough up phlegm; experience headaches, muscle, and/or joint pain; have nasal or eye congestion, or suffer from nausea or diarrhea. However, if you have one or more of these symptoms but not the top symptoms of COVID-19, you may simply have seasonal allergies, a cold, or the flu.

Seasonal allergy symptoms

Seasonal allergies usually present with one or more of the following allergy symptoms:

If you have severe allergies or asthma, you could also experience headaches, coughing, wheezing, and shortness of breath. Already having respiratory issues can make COVID-19 more dangerous to you, so practice good hygiene and try to avoid exposure.

Common cold symptoms

If you have a common cold, you may be experiencing one or more of these cold symptoms:

If your fever climbs, or if you start having shortness of breath, your cold may have developed into something more serious. You could have also been exposed to COVID-19, but you should only be worried if you are in a high-risk category (advanced in age, with existing respiratory problems, or with a compromised immune system.)

Flu symptoms

The flu is the main illness that can present with symptoms the most similar to top COVID-19 symptoms. Flu symptoms include:

The big COVID-19 symptom missing from the flu symptom list is a dry cough. However, it is possible to have one or the other and have different symptoms than the most common ones.

If you are worried you have COVID-19

The CDC has the following instructions if you think you may have COVID-19:

Call your doctor if you develop the following symptoms:

AND

Call ahead before you go to a doctor’s office or emergency room, and tell them about your symptoms and any recent travel or contact with travelers or people with confirmed cases. You don’t want to expose others unnecessarily.
