There are four sexually transmitted infections (STIs) that are not curable: herpes (HSV), hepatitis B (HBV), human immunodeficiency virus (HIV), and human papillomavirus (HPV) . These infections are caused by viruses that stay in the body for many years, and while they cannot be cured, they can be managed with treatment and medication). Other STIs, such as syphilis, gonorrhea, chlamydia, and trichomoniasis, are generally curable with antibiotics or antiviral medications). It is important to note that even though some STIs are curable, they can still cause significant harm if left untreated, and it is essential to seek medical attention if you suspect you have an STI. Practicing safe sex, such as using condoms, can also help prevent the spread of STIs).
