Which agency is concerned with the causes, spread, and control of diseases in populations?

The agency primarily concerned with the causes, spread, and control of diseases in populations is the Centers for Disease Control and Prevention (CDC). The CDC plays a crucial role in public health by conducting research and providing information on health issues, including infectious diseases, chronic diseases, and health threats. Its mission centers on protecting health and safety through the control and prevention of disease, injury, and disability.

The agency achieves this by monitoring disease outbreaks, conducting epidemiological studies, and implementing health promotion strategies. Its extensive resources and expertise allow it to respond effectively to health emergencies, guide public health policies, and educate communities about disease prevention and control.

The National Institutes of Health (NIH) focuses primarily on biomedical research and advancing medical knowledge, rather than the direct control and management of diseases in populations. The Food and Drug Administration (FDA) is primarily concerned with the safety and efficacy of medical products, foods, and cosmetics, and does not directly address the broader public health aspects of disease control. The World Health Organization (WHO) operates internationally and collaborates on global health issues, but for direct population-level disease control and data within the U.S., the CDC serves as the primary agency.
