Epidemiology of anaphylaxis: findings of the American College of Allergy, Asthma and Immunology Epidemiology of Anaphylaxis Working Group

Anaphylaxis is a relatively common problem, affecting up to 2% of the population. Further data on epinephrine dispensing could improve current estimates. Another way to improve current understanding would be through better population-based study designs in different geographic regions. A recurring theme was the importance of broader access to self-injectable epinephrine for high-risk populations. An improved epidemiologic understanding of this disorder would aid ongoing efforts to reduce morbidity and mortality from anaphylaxis and could provide important clues for primary prevention.
