Quick read
Key points
- 1
CPE (carbapenemase-producing Enterobacterales) refers to certain bacteria that have developed resistance to carbapenems, a group of antibiotics often used as a last resort for serious infections. Carrying CPE doesn't necessarily mean you're unwell — many people carry it in their gut without any symptoms at all (colonisation), though it can occasionally cause infection, particularly in people who are already unwell.

What is CPE?
CPE (carbapenemase-producing Enterobacterales) refers to certain bacteria that have developed resistance to carbapenems, a group of antibiotics often used as a last resort for serious infections. Carrying CPE doesn't necessarily mean you're unwell — many people carry it in their gut without any symptoms at all (colonisation), though it can occasionally cause infection, particularly in people who are already unwell.
CPE is a particular concern in healthcare settings because of its resistance to multiple antibiotics and its potential to spread between patients. Hospitals and care facilities follow strict infection control procedures, including screening and specific precautions, to prevent its spread.
02 · Understand
Clinical context
Carrying CPE is different from having a CPE infection
Many people who carry CPE in their gut have no symptoms and are not unwell — this is called colonisation, which is different from an active infection, though both require specific infection control precautions in healthcare settings.
03 · Act
If You're Told You Carry CPE
- 1Ask your healthcare team what this specifically means for your care and any precautions needed
- 2Follow any infection control guidance given during hospital stays or procedures
- 3Inform new healthcare providers if asked about your medical history, as this can affect antibiotic choices if you become unwell
04 · Prevent & manage
Practical steps
Follow Healthcare Infection Control Guidance Closely
If you're told you carry CPE, healthcare staff will explain any specific precautions needed during medical care — following this guidance helps protect both yourself and other patients.
- 1Follow specific infection control guidance from healthcare staff.This may include specific precautions during hospital stays or procedures.
- 2Practice good hand hygiene.This is one of the most effective ways to reduce the spread of many healthcare-associated bacteria, including CPE.
- 3Ask questions if you're unsure what a CPE result means for you.Healthcare staff can explain your specific situation clearly.
- 4Mention your CPE status to healthcare providers when relevant.This helps guide safe and effective antibiotic choices if you ever need treatment for an infection.
