Common indoor and outdoor aero-allergens in South Africa: identification of the allergen that is responsible for symptoms is the key to the management

It is important for every practitioner to be familiar with the

common allergens in South Africa to be able to make a specific allergy

diagnosis in specific patients.

South Africa, because of its wide range of ecological biomes, is

home to most of the common indoor and outdoor aero-allergens recognised

globally. It also has a number of indigenous grass, tree and insect

allergens, which appear to be unique to Africa.

One may be exposed to allergens indoors or outdoors, during

everyday life, or via inhalant, ingestant or cutaneous routes, but also

in an occupational environment.
