A pragmatic approach to investigating nosocomial acquisition of rare and emerging molds.

Outbreaks of rare and emerging molds in hospitals are linked to high mortality, requiring systematic investigation and strengthened surveillance systems.

• Why it matters: Limited information exists on how to assess and manage outbreaks of these molds, which can originate from unique environmental niches and cause nosocomial infections.
• What they did: The authors reviewed existing outbreak data and discussed actions such as environmental reassessment, risk assessment, and coordination with national agencies to manage these infections.
• The result: Implementing a systematic approach and enhancing surveillance may improve outbreak detection and prevention, ultimately reducing the high mortality associated with these mold infections.
