[95] In 1997, 0.4% children in the United States were reported to have peanut allergy, yet this number markedly rose to 1.4% in 2008. [96] In Australia, hospital admission rates for food-induced anaphylaxis increased by an average of 13.2% from 1994-2005. [93]

A case report in 1979 on EIA was the first research of its kind, where a patient was described to experience anaphylactic shock related to exercise 5–24 hours following the ...
