The bacteria spreads from people or objects that carry it. This can cause the infection.

A VRE infection is one that does not get better when a person takes vancomycin.

Risk Factors

Things that may raise the risk are:

  • Being treated with vancomycin or another antibiotic for a long time
  • Recent hospital or care center stay
  • Recent surgery or a device inserted
  • Having a weakened immune system from problems like cancer


Symptoms depend on where the infection is found. A person may have problems from a:

  • Urinary tract infection
  • Abdominal and pelvic infection
  • Surgical wound infection
  • Sepsis—an overreaction of the body to infection
  • Endocarditis—an infection of the inside of the heart muscles and valves
  • Meningitis—an infection of the layers that surround the brain and spinal cord


You will be asked about your symptoms and health history. A physical exam will be done.

Blood tests will be done. Samples will also be taken of the area that is infected. This can help the doctor choose an antibiotic that will treat it.

VRE infection can be treated with other antibiotics. The one that is chosen depends on the infection and how severe it is.

Catheter Removal

A person who has a catheter in place may have it removed. This lowers the risk of more infection.


Proper hand washing can lower the risk of VRE infection.
