Which activity is a concrete example of the Diagnose and investigate health problems essential public health service?

• A. Public health campaigns
• B. Health education in schools
• C. Monitoring health status to track community health
• D. Outbreak investigation

Answer: (D)

Diagnose and investigate health problems involves actively identifying and studying health events to determine their cause, scope, and the best way to intervene. An outbreak investigation is a concrete example because it starts with a cluster of cases, then investigators confirm cases, define the outbreak, collect and analyze data, identify the source and mode of transmission, and implement control measures to stop further spread. This is the practical, hands-on work of diagnosing a health problem and guiding the response.

Monitoring health status to track community health is essential for understanding trends and disease burden, but it’s about surveillance and data collection over time rather than actively diagnosing a specific problem. Public health campaigns and health education aim to promote prevention and awareness, not to diagnose or investigate a particular health event.
