What sets MRSA apart is that it is resistant to an entire class of antibiotics called beta-lactams. There are six links in the chain: Infectious Agent; Reservoirs; Portal of Exit; Modes of Transmission; Portals of Entry; Susceptible Host (PIDAC, 2012) You need to understand how an infectious agent travels throughout the cycle to determine how to break the chain and prevent the transmission of the infectious disease.

It can also cause sepsis, which is the body's overwhelming response to infection. MRSA is very contagious under certain circumstances (when skin alterations or damage are present); it spread occurs through person-to-person contact with a skin infection or even indirect contact, such as contact with a MRSA-infected person's clothing or towels or even from benches in gyms.. All MRSA needs to establish itself is a small break in the skin or mucosa. This can be done through indirect and direct contact, such as touching the same food as someone else or coming into contact with a sneeze. Further study of oxygen cylinders in an offsite oxygen cylinder storage area showed that 96% of the oxygen cylinders (67 out of 70) tested positive for MRSA colonization. Pathogen identification Asepsis & hygiene Infectious Agent:-also known as a pathogen and . Antibiotics includes methicillin, and each can be transmitted through skin- to -skin contact or through surfaces. MRSA frequently causes illness in people with a compromised immune system who spend time in the hospital and other healthcare facilities. 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. Reservoirs can include people, environmental surfaces, water, air, and so on. Reservoirs This could be a colonised or infected person, or contaminated equipment or environment.
