Allergy Symptoms vs COVID-19 Signs
Allergies vs COVID-19? What are the Symptoms?
Even the slightest tickle or sniffle can cause your mind to race in the COVID-19 era. Is it a cough? Flu? Allergies? Allergies? It’s easy to get caught in the cycle of isolation, uncertainty, and testing when health authorities urge anyone who is feeling unwell to stay at home and be tested. What if you don’t have a virus? Maybe your symptoms are caused by something less infectious, like hay fever or an allergic reaction.
Understanding the difference between viral infections, such as COVID-19, and allergic symptoms is important. This not only reduces unnecessary stress and isolation, but also helps to prevent testing centers from being overwhelmed. As many as millions of tests could be unnecessary in Australia, where one-fifth of the population suffers from allergies.
This article will guide you through the steps you should take to distinguish between COVID-19 and allergies. It will cover everything from what causes hayfever to subtle differences in symptoms and how to proceed if you are unsure.
What Causes Hay Fever?
Hayfever is a medical condition known as seasonal allergic rhinitis that affects 21% of Australians. About one-fifth of Australians suffer from sneezing and runny eyes due to allergens. Hayfever can affect you at any time of the year, depending on which allergens trigger it.

Tiny airborne particles like pollen, dust mites, and mould spores are the main cause of hayfever. Your immune system attacks these allergens when they enter your nose and eyes.
This immune response is a release of chemicals such as histamine in your bloodstream. These chemicals cause inflammation and irritation, which leads to classic hayfever symptoms: sneezing and nasal congestion. Itchy eyes and watery discharge are also common.
Hayfever is a seasonal condition that depends on the pollen type in the air. In Australia, the pollen count peaks in winter and spring because of flowering grasses and trees. Many parts of Australia also experience an increase in allergic reactions during autumn. This is mainly due to moulds growing in moist environments and an increase in the dust mite population.
Climate change is also a factor, as it has been shown to increase the intensity and duration of pollen seasons in certain regions, causing hayfever to be more severe and the prevalence to rise. People may be experiencing allergies outside of the “hayfever” season, making it harder to distinguish between viral infections and allergy symptoms.
Similar Symptoms of COVID-19 and Allergies Can Look Alike
Many symptoms are similar in both COVID-19 and allergies. Both conditions can lead to:
- Runny or stuffy nasal discharge
- Sneezing
- Cough
- Sore throat
- Fatigue (in varying degrees)
- Post-nasal drip (mucus running down the back of your throat)
The symptoms of rhinitis, which means inflammation in the nose, can look similar because it is caused by allergies or infections.
How can you tell whether you have a virus or if your body is reacting to pollens?
The Differences between COVID-19 Symptoms and Allergies
It’s common to be confused when you experience sniffles, sneezing, or a scratchy neck. Is it allergies, or is it something more serious, like COVID-19?. There are some similarities, but there are also key differences that can help you distinguish between the two. What you need to be aware of to ease your concerns and stay informed.
1. Fever and Body Aches
Fever is one of the most obvious signs that you are suffering from a viral infection and not allergies.
- Allergies: Do not cause fever. Even though you might feel tired or uneasy from congestion, your body temperature will remain normal.
- COVID-19 (and other viral infections: Fever can be a common sign. You may also feel muscle pain (myalgia), chills, and weakness. You likely have a virus if you notice a fever or a rise in temperature along with respiratory symptoms.
2. Itchy Nose, Throat, and Eyes
Itching is a hallmark of hayfever, particularly in the nose, throat, and eyes.
- Allergic reactions can cause persistent itching and watery, red eyes. You may find that you are rubbing your nose or eyes a lot.
- COVID-19, colds, an usually do not cause an itch. Allergies can cause a persistent itchy throat, not just a sore or irritated throat.
Allergies are the most likely cause if you have itchy, watery eyes and a twitching nose.

3. Sneezing Patterns
- Allergic reactions tend to cause long-lasting sneezing. These can last for several hours or be triggered by allergens repeatedly.
- Colds & COVID-19 Sneezing is common, but not always as severe or persistent.
Think allergy if you sneeze non-stop after being outside or around pets.
4. Nasal Discharge and Color
- Allergy nasal drainage: Usually watery and clear.
- Viral Infection Discharge: Starts clear, but can thicken or turn yellow/green as infection progresses.
Infections are more likely to cause thick, discolored mucus than allergies.
5. Duration of symptoms
- Allergic reactions: The symptoms can last weeks or even months, particularly if they are caused by allergens that you are exposed to daily. The symptoms may be intermittent and worsen in certain environments or times of the day.
- Viral Infections: They usually last 7-10 days. After that, the symptoms will usually disappear or significantly improve.
Allergies are more likely to be the cause if you have been sneezing and feeling congested every day for a few weeks.
6. Dark Circles and Sleep Quality
Poor sleep quality can be caused by chronic nasal congestion due to allergies. This leads to snoring, nd dark circles around the eyes. These dark patches can be caused by swollen veins beneath the eyes due to chronic inflammation.
Short-term viral infections are less likely to cause poor sleep and dark circles, but prolonged illness can affect rest.
What To do if You’re Not Sure?
Are you unsure if your symptoms are allergies or more serious? You are not alone. It can be difficult to determine the next step when symptoms are blurred together. What you can do to protect yourself, gain clarity, and stay safe.
Antihistamines: A Trial
Try non-sedating Antihistamines to differentiate between allergies, infections, and other conditions.
- It’s an indication that your allergies are to blame if you notice a significant improvement in symptoms after taking antihistamines.
- Seek medical advice if your symptoms don’timprovev or worsen despite antihistamines. If you experience a fever, breathing difficulties, or any other concerning symptoms, get tested for COVID-19.
Note: Sedating Antihistamines should not be used by young children during the day. They can make them drowsy.
Watch for Symptom Changes
If you have symptoms that are different from those of previous episodes of allergy (such as a new onsetof fever, a loss of taste, smell, or fatigue), then it is safer to consider them potentially infectious. Get tested.
Why is it Important to differentiate between Allergies and COVID-19
In times when there is no pandemic, it may not matter if your sniffles are caused by a virus or an allergy. You just treat the symptoms. COVID-19 is different. Correctly identifying symptoms can have a wider impact.
- Reduce unnecessaryisolation : People who have allergies and mistakenly isolate themselves for COVID-19 are missing out on school, work, and social interactions.
- Reducing the pressure on testing sites: Testing centers can become overwhelmed if all people with hayfever symptoms demand COVID tests. It is important to differentiate symptoms in order to ensure that tests are given only to those with the most severe symptoms.
- Protecting vulnerable groups: Accurate symptom assessment helps to prevent transmission if COVID-19 is involved.
- Effectively managing allergies: By recognizing allergies, people can seek treatment and improve their quality of life.
Hay Fever Management During the Pandemic
Here are some tips for managing your condition if you suspect you may have allergies or hay fever.
- Take antihistamines as needed during allergy seasons or when symptoms are heightened.
- For better control, consider nasal aerosols. These may require a doctor’s prescription.
- Reduce exposure to allergens by using air purifiers and washing bedding regularly.
- Shower/change your clothes when you come indoors after avoiding outdoor activities.
- If your symptoms do not improve, speak to your doctor. They may be able to recommend other therapies.

When to Get Tested and Seek Medical Care
If you meet the following criteria, then you should consider getting tested for COVID-19.
- You may experience symptoms that are different from your normal allergies, such as fever, muscle pain, and loss of taste or smell.
- You experience worsening symptoms, or they don’t improve within a few days.
- COVID-19 has been diagnosed in someone you have come into contact with.
- You may have chest pain or difficulty breathing.
Follow local health advice.
Conclusion
Understanding the differences between hayfever symptoms and the COVID-19 pandemic will help you to make an informed decision about when to test, when to treat symptoms at home, or when to seek medical attention.
Remember:
- Allergies are characterized by itching, sneezing,g and nasal discharge. There is no fever.
- Viral infections can cause fever, aches, and pains, and thicker mucus.
- Antihistamines are effective for a short time, but their duration and the response can give clues.
If in doubt, it is best to stay at home and have your blood tested.
By separating allergies from COVID-1,9 you are not only protecting your health, but also helping the community better manage its limited healthcare resources.
Stay informed, breathe easy, and stay healthy (literally). ).
