Contact tracing (or partner notification) is where any sexual partners you have had since you may have become infected with an STI should also go for sexual health test check, as they may also need to be treated.
Not all STIs need contact tracing (such as herpes or genital warts), but the more serious and health impacting conditions do (such as chlamydia, gonorrhoea, syphilis, hepatitis, etc.).
Your diagnosing doctor can discuss partner notification needs with you.
If contact tracing is recommended, there are ways to let your partners know they may have been exposed to an STIs without disclosing your identity (i.e. anonymously).
