The idea
Microorganisms are living things too small to see, and they are present in water, soil, air and on every human body.
In practice
The commonest are bacteria, viruses and fungi; many living on the body are harmless or helpful.
Where people slip
In surgery, the question is never whether microbes are present; it is whether they reach a place they should not be.
Your place on the trail
Every lesson rests on earlier ones and opens later ones. Tap any to jump.
