Common types of STDs include Chlamydia, gonorrhea, Trichomoniasis, and genital herpes.
Some of the most common STDs may not produce signs or symptoms.
When signs and symptoms of STDs do occur, they include:
Genital lesions or sores (as
with herpes or HPV)
Urethritis (with gonorrhea or Chlamydia)
Systemic symptoms that affect the entire body (such as HIV).
Bacteria, viruses, or parasites can cause STDs.
Treatment for STDs is generally directed toward the causative organism. For example, STDs caused by bacteria are typically curable with antibiotics.
Some STDs, like herpes and HIV infection, are not curable and persist for life.
Early tests to diagnose STDs are extremely important as well as STD counseling in regard to the risks of spreading the infection, and how to avoid spreading it to others.
