How is C. Diff Spread? Understanding Transmission and Preventing Contagion of C. Difficile Infections

Clostridioides difficile, or C. diff, is a very contagious bacteria that can cause serious infections, especially in healthcare settings. Knowing how C. diff spreads and following steps to control infection is important for patients, families, and healthcare workers.

What is a C. Diff Infection?

According to the CDC, c. diff is a germ that causes diarrhea and colitis (an inflammation of the colon). C. diff normally lives in the stomach and intestines, but under certain conditions it can grow and produce toxins that cause symptoms like severe diarrhea and stomach pain. Some people have C. diff without any symptoms, while others may get very sick and need treatment.

Common Symptoms of C. Diff Infection

Symptoms of C. diff infection (CDI) vary in severity, but may include:

• Watery diarrhea
• Abdominal pain or tenderness
• Fever
• Loss of appetite
• Nausea

If left untreated, C. diff infections can lead to complications, particularly in people with weakened immune systems or other risk factors.

Who is at Risk for C. Diff Infection?

Several factors increase the risk of C. diff infections, including:

• Antibiotic Use: Taking antibiotics disrupts the natural balance of good and bad bacteria in the gut. People are 7 to 10 times more likely to get C. diff while on antibiotics and during the month after (Source: CDC). 
• Age: Adults aged 65 and older are more likely to get C. diff.
• Hospitalization: Those recently hospitalized or in long-term care facilities are at higher risk due to frequent contact with contaminated surfaces.
• Weakened Immune Systems: Conditions that compromise immunity also elevate risk.
• Previous C. Diff Exposure: Individuals who have previously had C. diff infections or have been in contact with someone who has are more likely to contract the bacteria again.

How is C. Diff Spread?

1. Unwashed Hands: C. diff spores can be spread when people do not wash their hands thoroughly after using the bathroom or before eating.
2. Contaminated Surfaces: Objects contaminated with stool, such as bedrails, door handles, and bathroom fixtures, can spread the bacteria when touched.
3. Shared Items: In healthcare settings, shared items such as medical equipment or personal items may carry C. diff spores if not properly disinfected.

Is C. Diff Contagious from Person to Person?

Yes, C. diff is very contagious. Coming into contact with surfaces or materials that have C. diff spores can spread the infection. It can also spread from person to person through close contact, especially if people don’t follow good hygiene practices.

Treatment Options for C. Diff

Getting diarrhea during or after taking antibiotics is common, but it doesn’t always mean there’s a C. diff infection. If symptoms are severe, a doctor might order a stool test to check for C. diff. If the test is positive, treatment usually includes antibiotics designed to target and eliminate C. diff bacteria.

Preventing the Spread of C. Diff

Effective infection control and hygiene practices are critical in preventing the spread of C. diff, both in healthcare facilities and at home.

Tips for Reducing C. Diff Spread at Home and in Healthcare Facilities

• Handwashing: Always wash hands thoroughly with soap and water, as alcohol-based hand sanitizers do not effectively kill C. diff spores.
• Daily Hygiene: Patients should shower daily and wear clean clothes to reduce the spread of bacteria.
• Cleaning and Disinfecting Surfaces: Regularly clean and disinfect frequently touched surfaces, including faucet handles, toilet flushes, bedrails, and doorknobs. Use a diluted bleach solution, as bleach is effective against C. diff spores.
• Laundering Contaminated Linens: Wash any clothes or linens contaminated with stool separately in hot water with detergent and bleach, if fabric allows.
• Contact Precautions in Healthcare Settings: Healthcare workers should wear gowns and gloves when treating patients with C. diff to prevent spreading the bacteria to other patients or areas of the facility.

Helpful Resources for C. Diff Prevention

For further support in preventing the spread of C. diff in healthcare settings, the following resources offer practical tools and guidance:

• C. Diff: Information for Patients and Families (Brochure)
  Learn how to stop the spread of C. diff in your facility by downloading our informational brochure with infection control tips. This resource is perfect for educating staff, residents, and families on effective practices for containing C. diff infections.
• Assessment of Current CDI Prevention Activities
  Use our Assessment of Current CDI Prevention Activities tool to help your facility implement evidence-based practices proven to reduce C. diff infections. This tool guides facilities in evaluating and adopting preventive measures, ensuring a safer environment for all.

Understanding how C. diff spreads and following these safety steps can make a big difference in stopping infections and protecting people at risk from catching C. diff.
