Is an allergen a pathogen?

What is the difference between a pathogen and an allergen?

Did you know that there is a difference between allergens and pathogens? Only about 1 to 2 percent of all germs are pathogenic, which means they can make you sick, while allergenic germs trigger allergy-like symptoms. This can mean sneezing, itchy and watery eyes, or a stuffy nose.

The innate immune system regulates the body’s initial response to pathogen exposure and is responsible for catalysing the sensitisation process which leads to allergic reactions. This is a non-specific response which involves recognition of molecules entering the body that are shared by a group of pathogens.

Are allergens bacteria?

Pollens, environmental fungi, and house dust mites are examples of common allergens. Bacteria have a dual role in allergy. Usually, they are associated with protection, however, certain bacterial species promote the development and exacerbation of allergic inflammation.

Is allergy a virus or bacteria?

Allergy desensitization is a treatment that provides safe, gradual exposure to your triggers. Over time, your body learns how to encounter the source of your allergies without sending your immune system into overdrive.

How can I strengthen my immune system against allergies?

Medication such as antihistamines and Montelukast are generally considered safe so you should continue to use these. To the best of our knowledge, there is no reason to think that antihistamines would lower the immune response.
