The evolutionary advantage of allergic reaction. Introduction: The allergic reactions are not beneficial to people but still, people have allergic reactions. The reason lies behind the evolution and its connections to parasitic worms. In response to any of the foreign harmless substances, the immune system generates a defense mechanism, which causes reactions and results in skin rashes, inflammation, diarrhea, nausea, hypersensitivity, and vomiting. The reaction because of which all this occurs is termed as an allergic reaction.

An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
