Which of the following is included in disease control, epidemiology, surveillance, and regulation by local health departments?

• A. Surveillance and regulation
• B. Hospital marketing
• C. Private medical practice
• D. Insurance auditing

Answer: (A)

Local health departments protect communities by monitoring disease and enforcing health standards. Surveillance is the ongoing collection, analysis, and interpretation of health data to detect outbreaks, track trends, and guide interventions. Regulation involves enforcing public health laws and codes to prevent disease spread, such as reporting of communicable diseases, inspections for food safety, vaccination requirements, and environmental health rules. Together, these activities provide the data and the authorities needed to control disease and support epidemiology. The other options describe functions outside this public health scope: hospital marketing promotes a facility, private medical practice delivers individual clinical care, and insurance auditing focuses on financial oversight. Therefore, surveillance and regulation is the correct included activity.
