Droplets land directly on mucous membranes.Infected person coughs, sneezes, talks, sings,.Close contact with infected person (Secretion of infected person, Example: – Cough and sneezing.Īgent is coughed or sneezed out into the air Route of transmission from respiratory tract (Nose, Mouth) The way of the pathogen gets from the reservoir to the new host. The largest droplets settle out of the air rapidly, within seconds to minutes. These droplets carry viruses and transmit infection. People release respiratory fluids during exhalation (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing) in the form of droplets across a spectrum of sizes. Route by which the infectious micro-organism escapes or leaves the reservoir,Ĥ. For a human reservoir, the portal of exit can include blood, respiratory secretions, and anything exiting from the gastrointestinal or urinary tracts. person, water, food, animal, plant, soil or substance feces, intravenous fluid, and equipment in which an infectious agent normally lives and multiplies.Ī portal of exit is the means by which a pathogen exits from a reservoir. The infectious agent depends on the reservoir for survival, where it can reproduce itself in such manner that it can be transmitted to a susceptible host. In contrast, tuberculosis bacillus infects only a small number of people, usually people with weakened immune function, or those who are undernourished and living in crowded conditions.Īny disease-causing microorganisms (bacteria, virus, fungi, parasites etc).Ī reservoir is any person, animal, arthropod, plant, soil or substance (or combination of these) in which an infectious agent normally lives and multiplies. For example, the smallpox virus is particularly virulent, infecting almost all people exposed. The virulence of these pathogens depends on their number, their potency, their ability to enter and survive in the body, and the susceptibility of the host. (Pathogens) include not only bacteria but also viruses, fungi, and parasites.

If any link is broken the chain is broken and infection cannot be transmitted.

Reservoir (the normal location of pathogens).

The Spread of infection can be described as a chain with six components. The transmission of infection depends on six elements which link together like chains. Infection control and contact tracing are meant to break the chain, preventing a pathogen from spreading. The spread of an infection within a community is described as a “chain,” several interconnected steps that describe how a pathogen moves about.

IDENTIFY THE 6 COMPONENTS OF CHAIN OF INFECTION Medical or clean asepsis reduces the number of organisms and prevents their spread surgical or sterile asepsis includes procedures to eliminate microorganisms from an area and is practiced by surgical technologists and nurses. Surgical asepsis (“sterile technique”): practices that completely kill and eliminate microorganisms.Medical asepsis (“clean technique”): practices that kill some microorganisms to prevent them from spreading.Keeping sterilizing instrument inside plastic wrappers to prevent contamination before use.Sterilizing equipment and instruments before a procedure.

Disinfecting a patient’s skin using antiseptic wipes.

Using aseptic techniques prevents the spread of infection by harmful germs.

Purpose: a septic technique helps to prevent health care associated infection.

A technique used the practice and procedure to prevent contamination from pathogens.

Aseptic technique: It is a standard health care practice that helps to prevent the transfer of germs to or from an open wound and other susceptible areas on a patient’s body.

ASEPSIS: Asepsis is the state of being free from disease causing microorganisms such as bacteria, viruses, pathogenic fungi, and parasites.
