Allergies or cold?
A cold is formed when the immune system reacts to a virus. During seasonal allergies, the immune system reacts to an allergen.
Yes, some symptoms of a cold and an allergy are the same, but some differences make it easier to identify.
Here is a table that will help you figure out which disease you are dealing with.
Cold:
• Fever (sometimes);
• Itchy eyes (rarely);
• Sore throat (almost always);
• Sneezing (most often);
• Fatigue (sometimes);
• Runny nose (most often);
• Nasal congestion (most often);
• Cough (most often).
