Limit the speed of infection

Clostridium difficile (C. diff) is the most common healthcare-associated infection, causing antibiotic-associated diarrhea that may lead to pseudomembranous colitis and even death. C. diff has an enormous impact on healthcare systems worldwide. An estimated 124,0001 cases of Clostridium difficile infection (CDI) occur annually in Europe, costing the EU up to €3 billion per year.2

  • Flexibility & accessibility to take appropriate measures for isolation and prevention to limit the spread of infection.

Intended use
