VRE questions: what it is, whether it spreads, and how it is treated
Straight answers to the questions patients and families most often ask about VRE — vancomycin-resistant enterococci — from what VRE actually is to whether it is contagious and what treatment involves.
What is VRE?
VRE stands for vancomycin-resistant enterococci. Enterococci are bacteria that normally live in the human gut and bowel without causing harm. In some strains, the bacteria have changed so that vancomycin — a powerful antibiotic often held in reserve for serious infections — no longer kills them. Those strains are called VRE.
What is a VRE infection?
A VRE infection happens when these resistant bacteria move out of the gut and cause illness somewhere they should not be — most often the urinary tract, the bloodstream, a surgical wound, or around a catheter or drip line. Carrying VRE in the bowel without symptoms is called colonization, and is not the same as an infection.
Is VRE contagious?
VRE is not airborne and does not spread through coughing or sneezing. It passes by contact — usually on hands, clothing, medical equipment, or surfaces in a hospital or care home. Healthy people with intact skin and normal immune systems are at very low risk, which is why hand hygiene and contact precautions are the main defenses.
Can VRE cause death?
VRE can be life-threatening, particularly in bloodstream infections and in people who are already seriously ill, in intensive care, or immunocompromised. Most people who simply carry VRE never become ill. The outlook depends on where the infection is, the person's overall health, and which antibiotics still work against that strain.
How is VRE treated?
Treatment options are narrower than for ordinary enterococci, but they exist. Infectious disease specialists choose from agents such as linezolid, daptomycin, and tigecycline, sometimes in combination, guided by laboratory testing of the specific strain. Colonization without illness is usually not treated with antibiotics at all.
What does colonization with VRE mean?
Colonization means the bacteria are living in the bowel without causing illness. It still calls for precautions in hospital so the bacteria do not reach other patients, and doctors watch for any signs of infection. Most colonized people never become sick from it.
Is VRE the same as CRE?
No. VRE means vancomycin-resistant enterococci. CRE refers to carbapenem-resistant Enterobacterales, a different family of bacteria that includes E. coli and Klebsiella. VRE is by far the more common of the two in hospitals.
What can patients and families do to stay safe?
Ask healthcare workers to clean their hands before touching you or any medical device. Wash your own hands before eating and after using the bathroom. Take antibiotics exactly as prescribed, and tell your care team if you have been hospitalized elsewhere or have a history of resistant infections.
