# Community-Acquired Clostridioides difficile Infection: The Fox Among the Chickens

## TL;DR

Community-acquired Clostridioides difficile infection is rising, and distinguishing it from colonization is challenging, requiring better detection and infection control.

## Contribution

The paper highlights the growing recognition of community-acquired C. difficile infection and outlines diagnostic and prevention challenges.

## Key findings

- Community-acquired CDI is increasingly recognized and often presents within 48 hours of hospital admission.
- Spores can survive cooking and biofilms, posing contamination risks in food and environments.
- Asymptomatic carriage is difficult to distinguish from infection, requiring infection control measures.

## Abstract

Clostridioides difficile infection (CDI) appears mainly as nosocomial antibiotic-associated diarrhea, and community-acquired infection is increasingly being recognized. The threshold of asymptomatic colonization and the clinical manifestation of CDI need further elucidation. Community-acquired CDI (CA-CDI) should be considered when the disease commences within 48 h of admission to hospital or more than 12 weeks after discharge. Although CDI is not established as a food-borne or zoonotic disease, some data support that direction. The spores’ ability to survive standard cooking procedures and on abiotic surfaces, the formation of biofilms, and their survival within biofilms of other bacteria render even a low number of spores capable of food contamination and spread. Adequate enumeration methods for detecting a low number of spores in food have not been developed. Primary care physicians should take CA-CDI into consideration in the differential diagnosis of diarrhea, as there is a thin line between colonization and infection. In patients diagnosed with inflammatory bowel disease and other comorbidities, C. difficile can be the cause of recurrent disease and should be included in the estimation of diarrhea and worsening colitis symptoms. In the community setting, it is difficult to distinguish asymptomatic carriage from true infection. For asymptomatic carriage, antibiotic therapy is not suggested but contact isolation and hand-washing practices are required. Primary healthcare providers should be vigilant and implement infection control policies for the prevention of C. difficile spread.
