Sexually transmitted diseases (STDs) caused by bacteria are curable. Some of the most common bacterial STDs include gonorrhea, syphilis and chlamydia. The general course of treatment for these STDs is antibiotics, according to the University of North Carolina, Greensboro.
Gonorrhea is a type of bacterial STD that is spread from contact via oral, vaginal or anal sex with a person who is infected with the disease. No secretions, semen or blood have to be exchanged in order for the disease to be spread. The symptoms of syphilis take a long time to show up, which makes it particularly damaging, since in its later stages, it can cause heart disease, nerve dysfunction and even death. The FREEDOM Network states that although syphilis is curable, if it is not caught early, the damage it causes is irreversible.
In contrast to bacterial STDs, STDs that are caused by viruses cannot be cured. Examples of incurable STDs include HPV, HIV, hepatitis and herpes. Although there is no cure for these STDs, the symptoms they cause can be alleviated with various treatments. There is also a vaccine for HPV that can eliminate the chances of contraction, but it must be administered prior to exposure. There are no vaccines for any of the other viral STDs as of 2014, according to the FREEDOM Network.
