The new app offers quick and easy access to streamlined STI prevention, diagnosis, and treatment recommendations. The user-friendly interface includes more clinical care guidance, sexual history resources, patient materials, and other features to assist with patient management. The STI Treatment (Tx) Guidelines mobile app serves as a quick reference guide for doctors and related parties on the identification of and treatment for sexually transmitted diseases (STDs). The full STI Treatment Guidelines (cdc.gov) can be accessed at https://www.cdc.gov/std/treatment-guidelines/default.htm. The guidelines provide current evidence-based prevention, diagnostic and treatment recommendations that replace the 2015 guidance. The recommendations are intended to be a source for clinical guidance. Healthcare providers should always assess patients based on their clinical circumstances and local burden.
