We reviewed data obtained in October 2021–May 2023 from youth who reported a history of sexual activity upon admission to 1 of 12 juvenile justice facilities in Utah, USA, that offered screening for
Chlamydia trachomatis
and
Neisseria gonorrhoeae
. Urinalysis revealed
C. trachomatis
positivity of 10.77%,
N. gonorrhoeae
positivity of 1.08%, and coinfection
C. trachomatis N. gonorrhoeae
) of 0.90%. Prevalence of infection was similar for youths in rural and urban facilities. A total of 12.01% of those identifying as male and 14.01% of those identifying as female tested positive for
C. trachomatis,
N. gonorrhoeae
, or coinfection. Of young adults who tested positive, 74.65% received their results while incarcerated, all of whom accepted treatment. Our research underscores the feasibility of providing prompt
C. trachomatis
/
N. gonorrhoeae
screening and treatment in juvenile correctional facilities. The pervasiveness of infection emphasizes the urgent need for early identification and treatment for
C. trachomatis
and
N. gonorrhoeae
in incarcerated youth nationwide.
