What makes a host more susceptible to infection?
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 the 4 factors that make a person more susceptible 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 factors affect susceptibility to infection?
We all have different susceptibility
Multiple innate factors (e.g., age, nutritional status, genetics, immune competency, and pre-existing chronic diseases) and external variables (e.g., concurrent drug therapy) influence the overall susceptibility of a person exposed to a virus.
What factors may make a host susceptible to infection name at least 5?
Host susceptibility is affected by many factors such as nutritional status, intercurrent disease, pregnancy, immunosuppressive drugs and malignancy.
What does susceptible host mean?
The last link in the chain of infection is the susceptible host. This is the organism (e.g., You or your resident!) that will feel the effects of the infectious disease that has traveled through the chain of infection.
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 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.
Which of the following may lead to disease susceptibility?
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 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).
