  "account": "A new study modeled the transmission of Clostridioides difficile (C. diff) infections in hospital cancer units and found that most new infections were introduced by asymptomatic carriers, rather than symptomatic patients. The model, developed using six months of surveillance data and simulations of patient and staff connections in two oncology wards, revealed that asymptomatic colonized (AC) patients – those carrying C. diff without clinical signs – were responsible for 92% of transmissions resulting in new colonizations. Testing alone detected only 23% of C. diff carriers, indicating that symptom-based detection misses most patients who may contribute to transmission. The researchers hope their model can help identify contact points where infection risks are increased and inform protocols to prevent future disease transmission in immunocompromised cancer patients.",
  "summary": "In a new study, researchers modeled the transmission of Clostridioides difficile (C. diff) infections among patients in hospital cancer units. They found that most new infections were introduced by patients who were infected but not symptomatic at the time of admission, rather than by patients who were infected and symptomatic. The model provides a clearer picture of C. diff transmission events…",
