ICD-11

Anaphylaxis is a severe, life-threatening systemic hypersensitivity reaction characterised by being rapid in onset with potentially life-threatening airway, breathing, or circulatory problems and is usually, although not always, associated with skin and mucosal changes.

Anaphylaxis due to insect venom is a severe systemic hypersensitivity reaction with rapid onset of cutaneous, vascular or respiratory symptoms and signs, either singly or in any combination after exposure (mainly by sting) to an insect venom in a sensitized patient.
