Résumé
Anaphylaxis is a severe systemic hypersensitivity reaction with acute onset that can potentially be fatal. Currently, the worldwide incidence stands at approximately 46 cases per 100,000 people annually, with rates fluctuating between 0.49 and 328.7 per 100,000 person years1, with considerable variation across age groups and regions. Despite increasing global awareness, research into the prevalence of anaphylaxis within the Chinese population remains sparse.
