Periodically, DICON staff publish and distribute "FAQs" (Frequently Asked Questions) to member institutions. FAQs include information and opinions from DICON about infection control questions that member institutions have asked DICON staff to address. All identifying items have been removed from the FAQs in order to keep the name of the person or hospital asking the question anonymous. These FAQs serve to help DICON hospitals provide excellent care for their patients. These FAQs may be printed for distribution at each institution.
