• C. Disease prevention, health promotion, and data collection only.
• D. Disease prevention, health promotion, community engagement, crisis response, data collection, and policy implementation.

Answer: (D)

Local public health agencies have a broad, interconnected role that goes beyond any single task. They work to prevent disease and promote health through programs that address risk factors, educate communities, and support healthier environments. They collect and analyze data to monitor health status, identify trends, and guide decisions and resource use. They actively engage communities and partners to tailor approaches, build trust, and ensure equitable solutions. They coordinate crisis response and emergency management to detect threats, communicate risks, mobilize resources, and deliver timely services. They also translate evidence into practice by developing and implementing local policies and guidelines that shape how programs are delivered and regulated. Together, these functions capture the full spectrum of what local public health agencies do, not just a subset of activities.
