Which of the following sexually transmitted diseases is not curable?

Herpes II, caused by the herpes simplex virus (HSV-2), is a viral infection that is not curable. Once a person is infected with the virus, it remains in the body for life. While antiviral medications can manage symptoms and reduce the frequency of outbreaks, they do not eliminate the virus from the body. This characteristic makes herpes distinct from some other sexually transmitted infections (STIs), which can be effectively treated and cured with the appropriate antibiotic or antiviral treatments.

In contrast, chlamydia and gonorrhea are bacterial infections that can be cured with antibiotics. Trichomoniasis, also a curable infection, is treated with specific medications that eradicate the parasite responsible for the disease. Understanding the differences in treatment and transmissibility among these infections is crucial for effective prevention and management of STIs.
