Which sexually transmitted infection is treatable and curable?

Syphilis is a sexually transmitted infection (STI) that is both treatable and curable, which is why it is the correct choice. The infection is caused by the bacterium Treponema pallidum. When diagnosed in its early stages, syphilis can be effectively treated with antibiotics, particularly penicillin, allowing individuals to fully recover and prevent any further complications associated with the disease.

In contrast, some other STIs such as HIV and herpes simplex virus are chronic conditions. While they can be managed or suppressed with appropriate treatment, they are not curable. HPV has vaccines that can help prevent certain types of infections and some strains may resolve on their own, but the virus itself does not have a cure.

Understanding the differences in treatment and curability among various STIs is critical for effective public health strategies and individual health decisions. This highlights the importance of regular STI screenings, timely diagnosis, and treatment to manage these infections adequately.
