In the outbreak investigation sequence, which event occurs after Salmonella is identified?

• A. Hospital records are reviewed
• B. Public Health Lab receives the sample
• C. CDC declares an outbreak
• D. Patients are notified

Answer: (B)

When a specific pathogen is identified in an outbreak investigation, the immediate next step is to have the specimen sent to the Public Health Laboratory for confirmation and characterization. This step is essential because it validates the identification, provides precise typing (such as serotype or molecular patterns), and yields data that are crucial for linking cases and guiding the investigation. Only after laboratory confirmation and characterization can investigators reliably assess the scope of the outbreak and proceed with epidemiologic actions. Hospital records review, notifying patients, and a formal outbreak declaration are downstream activities that depend on having confirmed laboratory results and a defined set of cases. Those steps help quantify and communicate findings, but they follow once the lab has provided definitive confirmation and typing to anchor the investigation.
