CDC’s STD Treatment Guidelines are updated every four years to reflect changes in testing and treatment of STIs for specific populations. The Guidelines are available on the web, in wall chart and pocket guide formats, and in an eBook. Now, they also are available through a new mobile application, giving clinicians access to STI treatment information on their mobile devices just about anywhere. Having the most up-to-date treatment guidelines available in multiple formats translates to better access, better care, and, ultimately, better health.
