The STD Tx Guide is a mobile application that provides quick and easy access to streamlined STI prevention, diagnosis, and treatment recommendations. Developed by Centers for Disease Control and Prevention, the app features a user-friendly interface that includes more clinical care guidance, sexual history resources, and patient materials. It is designed to assist healthcare providers and related parties with patient management, offering a quick reference guide on the identification and treatment of sexually transmitted diseases (STDs).

The app is based on the full STI Treatment Guidelines available on cdc.gov, which provide up-to-date evidence-based prevention, diagnostic, and treatment recommendations. The guidelines replace the 2015 guidance and are intended to be a source for clinical guidance. It is important to note that healthcare providers should always assess patients based on their clinical circumstances and local burden. As a free app, it is a useful tool for healthcare professionals who deal with STIs and need a quick reference guide.
