Are we too clean for our own good?

  • Role of home and personal hygiene small relative to other factors.
  • Clean-looking homes full of bacteria, viruses, fungi, etc. 
  • Routine weekly cleaning - no sustained effect  on microbe levels
  • Cannot create  “sterile” home  - microbes constantly replaced via dust, air, body flora, pets, contaminated foods.

Key point may be:

  • Microbial content of homes now DIFFERENT - but not because of “increased” cleanliness
  • e.g modern urban homes – interact c different environment  cf rural homes prior to 1800s
  • helminths now relatively rare - up to 1950s 50% children infested with pinworm
