What are the factors that influence the susceptibility of the 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 three factors that could make someone a susceptible host for an infectious agent pathogen?
Whether exposure to a pathogen results in infection depends on several factors related to the person exposed (the host), the pathogen (the agent), and the environment.
What are four 4 factors that could increase the susceptibility to infection?
Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. These life style factors can therefore be considered to cause acquired susceptibility for increased risk for environmental disease.
What are the three 3 factors that affect the likelihood of infection from a pathogen?
Common pathogen factors are immune evasion, high viral load and low infectious dose.
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 factors increase the risk of infection?
11 Risk Factors for Infections Among the Elderly
- Diminished immune response.
- Advanced age.
- The presence of multiple chronic diseases, a status that is often accompanied by many different medications.
- Cognitive deficits that may complicate compliance with basic sanitary practices, such as hand washing.
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 is a susceptible host for influenza?
Influenza infections cause high morbidity and mortality rates in the elderly and very young populations. Individuals greater than 65 years of age are the most vulnerable to severe illness from influenza infection and account for about 90% of all influenza and influenza-related deaths (14).
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.
Which factors within the environment would increase the risk of infection?
A: Humans, Animals, Environment. Q: Which of the following factors within the environment could increase the risk of infection? A: Use of inappropriate products or equipment for cleaning, Cluttered and untidy work areas, Presence of rust or lime scale, Chipped or damaged work surfaces, Split flooring.
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.
