Key Differences in Symptoms: Allergic Rhinitis vs COVID-19
Allergic rhinitis and COVID-19 can share some overlapping symptoms, but there are clear differences that help distinguish between the two. COVID-19 is a contagious viral disease with systemic and respiratory symptoms, while allergic rhinitis is a non-contagious, non-viral condition caused by an immune response to allergensSalehi-Abari2020Hagemann2021Gani2021.
Typical Symptoms of Allergic Rhinitis
Allergic rhinitis is mainly characterized by:
- Runny nose
- Stuffy nose
- Sneezing
- Postnasal drip
- Itchy eyes and skin
These symptoms are usually triggered by exposure to allergens and often recur in a similar pattern each year for affected individualsSalehi-Abari2020Bruno2020Hagemann2021+1 MORE.
Typical Symptoms of COVID-19
COVID-19 commonly presents with:
- Fever
- Dry cough
- Shortness of breath (dyspnea)
- Fatigue
- Body aches
- Loss of smell (anosmia) and taste
While COVID-19 can also cause nasal symptoms like congestion or rhinorrhea, these are generally less prominent than in allergic rhinitis. Loss of smell and taste, cough, and systemic symptoms like fever and body aches are much more common and severe in COVID-19Salehi-Abari2020Bruno2020Hagemann2021+1 MORE.
Overlapping and Distinguishing Features
Some symptoms, such as nasal congestion and mild cough, can appear in both conditions, making it possible for mild COVID-19 to be mistaken for allergic rhinitis, especially by non-expertsSalehi-Abari2020Bruno2020Hagemann2021. However, sneezing and the need to blow the nose are much more frequent and severe in allergic rhinitis, while cough and loss of smell are more pronounced in COVID-19Bruno2020Hagemann2021.
Impact of Allergic Rhinitis on COVID-19 Severity
Research shows that having allergic rhinitis does not increase the risk of severe COVID-19 outcomes. In fact, some studies suggest that allergic rhinitis may even have a protective effect against severe COVID-19, while asthma is associated with a higher risk of severe diseaseGuvey2021Tenório2024. Proper management of allergic rhinitis, especially with intranasal corticosteroids, is recommended and may help control symptoms and reduce the risk of viral triggersShchurok2021Gani2021.
Influence of Treatments and Vaccination
Patients with allergic rhinitis who receive sublingual immunotherapy may experience fewer symptoms if they contract COVID-19 compared to those on conventional therapy. The evolution of COVID-19 symptoms can also be influenced by virus variants and vaccination status, but the main distinguishing features between allergic rhinitis and COVID-19 remain consistentHagemann2022Smith2022.
Practical Tips for Differentiation
- Allergic rhinitis symptoms are usually seasonal, recurrent, and improve with allergy medications.
- COVID-19 symptoms are often new, more severe, and include fever, cough, and loss of smell/taste.
- If symptoms are sudden, different from previous allergy episodes, or do not respond to usual allergy treatments, COVID-19 should be considered, especially during outbreaksSalehi-Abari2020Bruno2020Hagemann2021.
Conclusion
While allergic rhinitis and COVID-19 can share some nasal symptoms, key differences—such as the presence of fever, cough, and loss of smell/taste in COVID-19, and sneezing and itchy eyes in allergic rhinitis—help distinguish between the two. Proper diagnosis is important to avoid confusion and ensure appropriate managementSalehi-Abari2020Bruno2020Hagemann2021+1 MORE.
