These are gonorrhea, syphilis, trichomoniasis, and chlamydia.
The other four viral infections, which are not treatable are herpes simplex virus, hepatitis B, human papillomavirus, and HIV. However, the signs and symptoms of these diseases because of the untreatable viral infections can be modified or reduced via treatment.
The viral STD that does not have a cure is AIDS. Therefore, option D is correct.
AIDS (Acquired Immunodeficiency Syndrome) is caused by the human immunodeficiency virus (HIV), which attacks the immune system and weakens its ability to fight off infections and diseases.
