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.
Devices like IV catheters and surgical incisions can provide an entryway, whereas a healthy immune system helps fight infection.
When patients are sick and receive medical treatment in healthcare facilities, the following factors can increase their susceptibility to infection.
Recognizing the factors that increase patients’ susceptibility to infection allows providers to recognize risks and perform basic infection prevention measures to prevent infection from occurring.
