Contributor(s): Rosanna Marsella, David Scarff

Introduction

Pathogenesis

Etiology

Pathophysiology

  • Toxins and excretory products produced by ectoparasites act as direct irritants and/or via their potential as allergens.

Timecourse

  • Generally sudden onset (in contrast to atopy Skin: atopy ).

Epidemiology

  • Variable depending on insect or arachnid involved.
  • Some live permanently/semi-permanently on host, egCheyletiella, lice. Others are 'visitors', eg mosquitoes, bees.
