Vancomycin-resistant enterococci - hospital
Super-bugs; VRE; Gastroenteritis - VRE; Colitis - VRE; Hospital acquired infection - VRE
Enterococcus is a germ (bacteria). It normally lives in the intestines and in the female genital tract.
Most of the time, it does not cause problems. But Enterococcus can cause an infection if it gets into the urinary tract, bloodstream, or skin wounds.
Vancomycin is an antibiotic that is often used to treat these infections. Antibiotics are medicines that are used to kill bacteria.
Enterococcus germs that vancomycin does not kill are called vancomycin-resistant enterococci (VRE). VRE can be hard to treat because there are fewer antibiotics that can fight the bacteria. Most VRE infections occur in hospitals.
Who is Most at Risk for VRE?
VRE infections are more common in people who:
- Are in the hospital, especially if they are taking antibiotics for a long time
- Are older
- Have long-term illnesses or weak immune systems
- Have been treated before with vancomycin, or other antibiotics for a long time
- Have been in intensive care units (ICUs)
- Have been in cancer or transplant units
- Have had major surgery
- Have catheters to drain urine or intravenous (IV) catheters that stay in for a long time
Preventing the Spread of VRE in the Hospital
VRE can get onto the hands by touching a person who has VRE or by touching a surface that is contaminated with VRE. The bacteria then spread from one person to another by touch.
The best way to prevent the spread of VRE is for everyone to keep their hands clean.
- Hospital staff and health care providers must wash with soap and water or an alcohol-based hand sanitizer before and after caring for every patient.
- Patients should wash their hands if they move around the room or the hospital.
- Visitors also need to take steps to prevent spreading germs.
Urinary catheters or IV tubing are changed on a regular basis to minimize the risk of VRE infections.
Patients infected with VRE may be placed in a single room or be in a semi-private room with another patient with VRE. This prevents the spread of germs among hospital staff, other patients, and visitors. Staff and providers may need to:
- Use proper garments, such as gowns and gloves when entering an infected patient's room
- Wear a mask when there is a chance of splashing bodily fluids
Treating VRE Infections
Often, other antibiotics besides vancomycin can be used to treat most VRE infections. Lab tests will tell which antibiotics will kill the germ.
Patients with the Enterococcus germ who do not have symptoms of an infection DO NOT need treatment.
