In the infographic below, it represents six areas where the chain must be broken to stop germs from infecting another person. 9. Reservoirs This could be a colonised or infected person, or contaminated equipment or environment. The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Methicillin-resistant Staphylococcus aureus (MRSA) infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections. MRSA that is acquired in a hospital or health care setting is called healthcare-associated methicillin-resistant Staphylococcus aureus (HA-MRSA). MRSA stands for Methicillin Resistant Staphyloccus Aureus, but many people are more familiar with the name "staph infection." MRSA can be transmitted through skin- to -skin contact or through infected surfaces. No matter the germ, there are six points at which the chain can be broken and a germ can be stopped from infecting another person.

Also, people who carry MRSA but do not have signs of infection can spread the bacteria to others (i.e., people who are colonized). The Association for Professionals in Infections Control (APIC), has just released a comprehensive study that found MRSA rates may be much higher than earlier thought.

This is often referred to as the Chain of Infection. MRSA is contagious and can be spread to other people through skin-to- skin contact. The chain of infection can be detailed in six steps: The microorganism is the infectious agent introduced. Infection transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host.

Each step is a link in this chain, and if all the links are present, then an infection will develop. The environment contains a large number of reservoirs of infection, including soil (which acts as a reservoir for Clostridium tetani, the causative agent of tetanus) and water (which is a reservoir for Legionella pneumophila, the causative agent of Legionnaires disease).
