Aeroallergen

Aeroallergen (pronunciation: /ˈeɪrəʊˌælərdʒən/) is a type of allergen that is airborne and can cause an allergic reaction in susceptible individuals.

Etymology

The term "aeroallergen" is derived from the Greek words "aero" meaning air and "allergen" meaning causing an allergic reaction.

Definition

An aeroallergen is a substance that is present in the air and can provoke an allergic reaction in certain individuals. These allergens can be inhaled, ingested, or come into contact with the skin, leading to allergic reactions such as asthma, hay fever, or dermatitis.

Types of Aeroallergens

There are several types of aeroallergens, including:

Pollen: This is a common aeroallergen that comes from trees, grasses, and weeds. It is most prevalent in the spring and fall seasons.
Dust Mites: These are tiny insects that live in household dust. They are a common cause of asthma and allergic rhinitis.
Mold Spores: These are produced by molds and fungi and can be found both indoors and outdoors.
Pet Dander: This is composed of tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers.
