Breaking the Chain
Captions available
The idea
Every infection-control habit breaks one or more links in the chain.
In practice
Hand hygiene and personal protective equipment block transmission; covering coughs blocks a portal of exit; disinfecting surfaces and sterilizing instruments remove reservoirs.
Where people slip
A single skipped link-breaker, such as unwashed hands, can undo all the others.
