- Break the Chain of Infection
There are many different germs and infections inside and outside of the healthcare setting Despite the variety of viruses and bacteria, germs spread from person to person through a common series of events Therefore, to prevent germs from infecting more people, we must break the chain of infection No matter the germ, there are six points at which the chain can be broken and a germ can be
