In this regard, why are some people more vulnerable to infection?

Often, when people age, there is immunosenescence, which means that the immune system doesn't function as well or as vigorously. The combination of increased comorbid conditions and the decrease in activity of the immune system can make people more prone to infections.

Likewise, what are the risk factors for infection? Having other medical conditions such as diabetes, chronic obstructive pulmonary disease (COPD), autoimmune disease, among others. If you have other medical conditions, ask your doctor if they put you at increased risk for infection. Other factors, such as poor nutrition, stress, or lack of sleep.

How does infection get into the body?

Entering the Human Host

Why are older people at greater risk of infection?

The elderly are more susceptible to infection, which is attributed to a less capable immune response to infectious challenges. Multiple determinants, such as diseases, conditions, or exposures, affect the risk of infection in older adults by contributing to declining immune function.

Who is at risk of malaria?

People who are heavily exposed to the bites of mosquitoes infected with P. falciparum are most at risk of dying from 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.

What is high risk population?

High-Risk Population. Populations at risk are mostly immunocompromised subjects, such as patients with neutropenia, immunosuppressive therapy, malignancies, chronic diseases such as diabetes, stem cell and solid organ transplants and chronic renal failure.

What increases the risk of infection?

The main types of germs are bacteria, viruses, protozoa (some of which act as parasites), and fungal organisms (also called fungi). Cancer itself can increase your risk of getting a life-threatening infection. Your risk of infection also depends on the type of cancer you have and the treatment you get.

What makes a person susceptible to infection?

Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. This suggests that exposure to high enough concentrations of certain mutagens can cause acquired susceptibility in human populations.
