Which organization focuses on prevention and control of diseases within the public health domain?

The Centers for Disease Control and Prevention (CDC) is a key organization that focuses specifically on the prevention and control of diseases, making it the correct choice. The CDC plays a pivotal role in public health, conducting extensive research and providing guidance on health threats, disease outbreaks, and health promotion strategies. Its mission includes protecting public health by controlling and preventing diseases, monitoring health trends, and delivering health education to the public and health professionals.

In contrast, while the National Institute for Occupational Safety and Health (NIOSH) is concerned with occupational safety and health, it does not primarily focus on the broader public health domain. The Occupational Safety and Health Administration (OSHA) is focused on ensuring safe and healthy working conditions by setting and enforcing standards, rather than on disease prevention in the general population. The Food and Drug Administration (FDA) regulates food safety and drug approval processes, which, while related to public health, do not cover the full spectrum of disease prevention and control that the CDC addresses. Thus, the CDC is uniquely positioned as the primary agency dedicated to these public health efforts.
