Understanding the difference between allergy and COVID-19 symptoms is crucial for appropriate treatment and peace of mind. Allergies, typically non-viral, arise from the immune system reacting to harmless substances like pollen. Common allergy symptoms include nasal congestion, runny nose, and increased secretions. However, allergies rarely cause severe fatigue or body aches, symptoms often linked with COVID-19.

Allergic diseases are one of the most common chronic health conditions globally. While most allergies manifest early in life, it is possible to develop seasonal allergies at any age, as the immune system changes over time. On the other hand, COVID-19 symptoms can mirror allergy symptoms but also include chills, fever, body aches, and loss of taste and smell—distinct signs not typically associated with allergies.

To confirm allergies, an allergy skin test may be conducted. If you’re grappling with brain fog due to seasonal allergies, strategies like reducing exposure and managing symptoms early can help. People with a family history of allergies are at a higher risk for allergic diseases, which range from hay fever to life-threatening reactions.
