Hospitalized patients with Clostridium difficile infection (CDI) transmit C. difficile at a much higher rate than that of asymptomatic carriers and community sources, according to a report published in the April issue of the USCDC’s Emerging Infectious Diseases.

Researchers found that hospitalized patients with CDI transmitted C. difficile at a rate 15 times that of asymptomatic patients, based on parametrizing the model from national databases and calibrating it to C. difficile prevalence and CDI incidence.

Within the long-term care facility, the transmission rate from a person with CDI to an uncolonized person was 27% that of the hospital rate, while for persons in the community the transmission rate was 0.1% of that in the hospital.
