The Centers for Disease Control and Prevention (CDC) is a federal agency that monitors diseases in the United States and attempts to promote healthier behaviors. It is the main source of public information regarding sexually transmitted disease (STD) prevention and sexual health.

The CDC provides sex health statistics to physicians and health organizations, occasionally making suggestions and promoting policies that could prevent diseases and infections from spreading. For example, the agency takes a prominent stance regarding condom usage, maintaining that correct and consistent condom use can significantly lower the chances of sexually transmitted infection (STI) transmission.
