Which surveillance framework is often used in conjunction with specific epidemiologic investigations?

• A. Wastewater Surveillance
• B. Registries
• C. Passive Surveillance
• D. Active Surveillance

Answer: (D)

The main idea is proactive case finding during an investigation. Active surveillance means investigators directly seek out cases, collect data, perform rapid testing, and follow up with contacts to understand the scope, transmission, and exposure pathways in real time. This approach is specifically suited to a targeted epidemiologic investigation because it provides timely, comprehensive data and can quickly identify additional cases that would be missed if we waited for reports. Wastewater surveillance looks for a signal at the community level rather than identifying and counting individual cases tied to a single investigation. Registries organize and store data over time but don’t by themselves drive proactive case finding during an investigation. Passive surveillance relies on reports that come in from providers, which can miss cases and delay the investigation.
