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

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?

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.
