Which organization oversees diseases in the United States?

The Centers for Disease Control and Prevention (CDC) is the primary organization overseeing public health in the United States, including the monitoring and management of diseases. The CDC plays a crucial role in tracking disease outbreaks, conducting research, and providing guidance for public health practices to protect and improve the health of the American population. It also works on prevention strategies, health education, and response coordination during health emergencies.

While the FDA (Food and Drug Administration) is responsible for regulating food safety, pharmaceuticals, and medical devices, it does not focus specifically on disease oversight. The NIAID (National Institute of Allergy and Infectious Diseases) is part of the National Institutes of Health and primarily conducts research on infectious diseases and allergies. The WHO (World Health Organization) operates globally and helps coordinate international health responses, but its jurisdiction does not extend to direct oversight within the United States.

Therefore, the CDC is the correct answer as the organization most directly involved in overseeing disease control and prevention efforts nationally.
