Which entity makes and enforces regulations pertaining to dangerous infections in humans?

• A. American Red Cross
• B. Surgeon General
• C. Planned Parenthood
• D. National Institutes of Health

Answer: (B)

The national public health official is the one who makes and communicates official health guidance and coordinates actions to prevent and control serious infections. This role leads national health policy and works with agencies like the CDC to implement regulations that protect people from dangerous infections. The other options are not responsible for regulatory authority: the American Red Cross is a relief organization, the NIH focuses on biomedical research, and Planned Parenthood provides clinical services and education. Therefore, the Surgeon General is the best fit for this regulatory responsibility.
