SUSCEPTIBLE PERSON (HOST) A susceptible or non-immune person is one who has little resistance against a particular organism and who, if exposed to this organism, is likely to contract disease.

What is the most effective way of preventing cross infection?

Having clean hands is the most effective way of preventing infection from spreading.

What is the first step in the chain of infection?

The spread of infection can be described as a chain with six links:Infectious agent (pathogen)Reservoir (the normal location of the pathogen)Portal of exit from the reservoir.Mode of transmission.Portal of entry into a host.Susceptible host.

Terms in this set (6)Infectious agent. First stage; pathogen.Reservoir host. Second stage; place or host where the pathogen lives/resides.Portal of exit. Third stage; route of escape of the pathogen from the reservoir.Route of transmission. … Portal of entry. … Susceptible host.

How do you break the chain of infection at each link?

Break the chain by cleaning your hands frequently, staying up to date on your vaccines (including the flu shot), covering coughs and sneezes and staying home when sick, following the rules for standard and contact isolation, using personal protective equipment the right way, cleaning and disinfecting the environment, …

The Chain is broken by: • Wearing gloves to prevent the potentially Infectious Agent from entering the housekeeper’s skin through cuts or crapes (Portal of Entry) • Cleaning and disinfecting the floor removes the potentially Infectious Agent (blood) which blocks the Mode of Transmission (contact) The person whose blood …

Who is considered a susceptible host?

Host. The final link in the chain of infection is a susceptible host. Susceptibility of a host depends on genetic or constitutional factors, specific immunity, and nonspecific factors that affect an individual’s ability to resist infection or to limit pathogenicity.

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 stopped from infecting another person. The six links include: The infectious agent is the pathogen (germ) that causes the disease.

How is Toxigenicity defined?

toxigenicity. The ability of a pathogenic organism to produce injurious substances that damage the host.

What is the first stage in the infectious process quizlet?

What is the first stage in the infectious process? Colonization.

What is the chain of infection quizlet?

Only $2.99/month. A sequence of circumstances where all events must occur to develop an infection.

Which disease is communicable and can be asymptomatic?

Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, HIV, C. difficile, influenzas, cholera, tuberculosis and COVID-19, although the latter is often associated with “robust T-cell immunity” in more than a quarter of patients studied.

What is the chain of infection for tuberculosis?

tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.

How does breaking the chain of infection Minimises the spread of infection?

Certain conditions must be met in order for a microbe or infectious disease to be spread from person to person. This process, called the chain of infection, can only occur when all six links in the chain are intact. By breaking this chain at any of the links, the spread of infection is stopped.

What is an agent of infection?

Infectious diseases are caused by diverse living agents that replicate in their hosts. The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms).

The means of transmission is the weakest link in the chain of infection, and it is the only link we can hope to eliminate entirely. Most infection control efforts are aimed at preventing the transport of germs from the reservoir to the susceptible host.

What are the 6 parts of the chain of infection?

The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting the chain at any link.

How does hand washing break the chain of infection?

Hand hygiene is a very effective way to control the spread of infection. Hand hygiene means washing hands with soap and water, or using an alcohol-based hand rub. The most effective method of hand hygiene is soap and water. Washing your hands with soap and running water loosens, dilutes and flushes off dirt and germs.

What is the susceptible host in the chain of infection?

SUSCEPTIBLE HOST The person who is at risk for developing an infection from the disease.

At what point in the chain of infection can disease be prevented quizlet?

Infection control is based on the fact that the transmission of infectious diseases will be prevented or stopped when any level in the chain is broken or interrupted.

Infection control experts agree that following standard precautions, isolation guidelines when required and engaging in proper handwashing is essential to breaking the chain of infection. Following aseptic technique is especially critical when caring for patients with hardy microorganisms such as MRSA.
