What is the first step an infection preventionist should take if routine surveillance indicates a potential outbreak?

• A. Confirm the outbreak.
• B. Notify hospital administration.
• C. Implement full isolation precautions immediately.
• D. Stop surveillance.

Answer: (A)

Verifying that an outbreak is actually occurring is essential. Routine surveillance can flag something that looks like clustering, but data can be incomplete, misentered, or fall within normal fluctuation. The first step is to confirm the signal by reviewing the data with a clear case definition, checking that cases are correctly identified, and assessing whether the number and pattern of cases truly exceed the expected baseline. This may involve rechecking lab results, confirming dates and locations, and ensuring the clustering isn’t just a data artifact. Only after this confirmation should there be escalation—informing hospital leadership and implementing appropriate, targeted infection control actions based on the likely transmission route. Jumping to broad isolation or other drastic steps before confirmation can misallocate resources and misguide response. Stopping surveillance would prevent appropriate detection and response in a real outbreak scenario.
