NewsSuperbugs spread to family members of recently hospitalized patients
Family members of patients recently discharged from hospital may have a higher risk of getting an antibiotic-resistant infection, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in community spread of resistant bacteria.
