timing of sexual intercourse following scabies treatment

Various guidance states that sexual relationships should be avoided until the full-course of scabies treatment has been undertaken:

• patients should be advised to avoid close contact until they and their sexual partners have completed treatment (1)
  
  
• infested individuals should be advised to avoid close physical contact until they and their sexual partners have completed treatment (2)
  
  
• the NHS website states (3):
  • do not have sex or close physical contact until you have completed the full course of treatment

Notes:

• transmission of a single pregnant mite, or of several larvae, suffices to infest another human host (4)
  • in common scabies, this requires intensive skin-to-skin contact of at least 5–10 minutes’ duration, as occurs, for example, in the breastfeeding or cuddling of an infant, sexual intercourse, or the care of nursing-dependent persons
