Mode of Transmission
  • Direct contact
    •  
    Direct contact - some things can only travel by direct contact. eg scabies,
    leprosy. You have to have direct skin contact. They can not live in the
    environment. (so pretty rare)
     
  • Indirect and Direct Contact
    •  
    more common: Equipment and the environment can be contaminated with live
    organisms/spores that have been transferred from an infected source and can
    survive in new environment ready to be transferred somewhere else on additional
    contact. 
     
  • Faeco-oral
    •  
    Faeco-oral - can be indirect via environment, food, water, sometimes can even
    become airborne and settles on food eg norovirus, etc. e.g. C.diff - spores
    contaminate the environment, picked up on the patient's hands, transferred to
    their mouth and from there enter the gut and multiply
