​Chlamydia is the most common reportable communicable disease in the United States, with the highest case rates occurring in female 20- to 24-year-olds followed closely by rates in female 15- to 19-year-olds. 

CDC Fact Sheet on Chlamydia - Detailed fact sheets are intended for physicians and individuals with specific questions about STIs. Detailed fact sheets include specific testing and treatment recommendations as well as citations so the reader can research the topic more in depth. 


Signs/symptoms, prevention, and treatment – provides information for parents, patients, and families on STIs, both in general and on specific STIs. 

STIs in Adolescents - Information from the AAP Red Book, the authority on pediatric infectious diseases, focused on epidemiology, evaluation, management, prevention, and treatment of STIs in adolescents 


The best way to prevent a chlamydial infection is abstinence from anal, oral, and vaginal sex. However, use of male latex condoms is a good way to reduce the risk of getting or giving chlamydia. 

Here are some guidelines for preventing and screening for Chlamydia  

  • Condom Use policy statement (AAP)– This statement was developed to assist pediatricians in understanding and supporting the use of condoms when counseling adolescents about preventing STIs.  ​

  • Why Screen for Chlamydia  A How-To Implementation Guide for Healthcare Providers (3rd Edition) outlines effective strategies and tips for increasing rates of chlamydia screening and retesting in clinical settings. The guide covers sexual history-taking, testing and treatment, partner notification and management, and providing confidential services to adolescents. 

  • Chlamydia and gonorrhea screening recommendations from the US Preventive Services Task Force - The USPSTF found inadequate evidence that screening for chlamydia and gonorrhea reduces complications of infection and transmission or acquisition of either disease or HIV in men.
