Under the Public Health Service Act, enforcement can include which tool?

• A. Immigration enforcement
• B. Fire code enforcement
• C. Quarantine and isolation
• D. Tax audits

Answer: (C)

Public health enforcement relies on quarantine and isolation to stop the spread of contagious diseases. Quarantine restricts the movement of people who may have been exposed to a contagious disease but are not yet ill, while isolation separates those who are known to be infected from others. These tools are legally empowered under the Public Health Service Act to prevent transmission during outbreaks, making them central to controlling disease spread in a community.

Other options do not fit this authority: immigration enforcement addresses border and entry issues, fire code enforcement relates to building safety, and tax audits are a financial regulatory tool.
