The Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) are co-sponsoring this public virtual workshop.

Discussions are planned around the following topics/areas:

  • The current state of development of pathogen-directed products used to prevent healthcare-associated infections (HAIs)
  • Evidence supporting decolonization and pathogen reduction (in colonized patients) as a strategy to prevent infection and transmission of antimicrobial-resistant healthcare-associated pathogens
  • Antimicrobial resistance threats as potential targets for decolonization and pathogen reduction
  • Challenges and potential approaches to drug development and registration of products for the prevention of healthcare-associated infections
