Other Factors to Consider
ƒ Previous history
Previous history of anaphylaxis is a strong predictor of future anaphylaxis. However, at least 25% of adults and 65% of children presenting with anaphylaxis do not report a previous episode.10
ƒ Age
The highest incidence of anaphylaxis occurs in individuals aged 0 to 19 years. Food is the most
common cause of anaphylaxis in children, adolescents and young adults. In middle-aged and older adults, medications and insect venom are the most common causes.11
