What makes a person a susceptible host?

What are some things that make someone 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. An individual’s genetic makeup may either increase or decrease susceptibility.

What are four 4 factors that influence the susceptibility of a host?

Susceptibility and response to an agent are influenced by factors such as genetic composition, nutritional and immunologic status, anatomic structure, presence of disease or medications, and psychological makeup.

What is a susceptible person?

Susceptible Person. A susceptible person is someone who is not vaccinated or otherwise immune, or a person with a weakened immune system who has a way for the germs to enter the body. For an infection to occur, germs must enter a susceptible person’s body and invade tissues, multiply, and cause a reaction.

What best describes a susceptible host?

Susceptible host can be any person (the most vulnerable of whom are receiving healthcare, are immunocompromised, or have invasive medical devices including lines, devices, and airways)

What are 2/3 things that may make a host more or less susceptible to an infectious disease?

Factors that increase the susceptibility of a host to the development of a communicable disease are called risk factors. Some risk factors arise from outside the individual – for example, poor personal hygiene, or poor control of reservoirs of infection in the environment.

What are susceptibility factors?

A condition that increases a person’s likelihood of acquiring a disease. The propensity to develop disease is often the result of a genetic mutation in a single base DNA base pair. See also: factor.

What makes a patient more susceptible to infection?

Older adults become more susceptible to infections due to several factors. As people get older, it is more frequent that they have comorbid conditions, such as diabetes, renal insufficiency and arthritis. Many comorbid conditions, both the number and type of comorbid conditions, predispose people to infections.

What are five factors that make someone a susceptible host to an infection?

Host susceptibility is affected by many factors such as nutritional status, intercurrent disease, pregnancy, immunosuppressive drugs and malignancy.

What are susceptible diseases?

Disease Susceptibility is a condition in which the individual is at a risk of getting infected by a disease. Some diseases that are thought to have an inherited or genetic component are seen to cluster in families and affect more than one generation, but without a clear pattern of inheritance as for monogenic diseases.

What is the susceptible host of malaria?

People who have little or no immunity to malaria, such as young children and pregnant women or travelers coming from areas with no malaria, are more likely to become very sick and die. Poor people living in rural areas who lack access to health care are at greater risk for this disease.

What does susceptibility mean in epidemiology?

Susceptibility: The state of being susceptible (easily affected / infected). A susceptible person does not possess sufficient resistance against a particular pathogen to prevent contracting that infection or disease when exposed to the pathogen.

What is classed as an endogenous infection?

n. An infection caused by an infectious agent that is already present in the body, but has previously been inapparent or dormant.

What is an example of an exogenous infection?

A significant amount of prominent diseases are induced by exogenous bacteria such as gonorrhea, meningitis, tetanus, and syphilis. Pathogenic exogenous bacteria can enter a host via cutaneous transmission, inhalation, and consumption.

How do infective agents enter the body?

Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.
