Sexually transmitted diseases are infections passed between humans through various types of sexual contact, caused by microorganisms including viruses, bacteria, and parasites.
Causes and Types of Sexually Transmitted Diseases
The organisms causing these infections are divided into three main types:
- Bacteria: Single-celled organisms that cause diseases such as gonorrhea, syphilis, chlamydia, and chancroid.
- Viruses: Microscopic organisms that replicate inside host cells, such as HIV/AIDS, genital herpes, hepatitis, and Human Papillomavirus (HPV).
- Parasites: Small organisms that feed on the host, such as pubic lice.
Details of Common Infections
Bacterial Infections
- Chlamydia: One of the most common bacterial infections, which may be asymptomatic. It causes abnormal discharge and burning during urination; in STDs in women, it may lead to pelvic inflammatory disease and infertility.
- Gonorrhea: Causes discharge from the penis or vagina and pain during urination. It may develop into ectopic pregnancy or infertility in women, and epididymitis in men.
- Syphilis: Begins as a painless open sore. If left untreated, it can progress through stages over several years, eventually affecting the heart and brain.
Viral Infections
- AIDS: Results from the Human Immunodeficiency Virus (HIV), which weakens the immune system. Early stages are marked by fever and extreme fatigue.
- Genital Herpes: Causes painful blisters or ulcers in the genital area. The virus remains in the body for life, and the infection may reactivate periodically.
- Genital Warts: Caused by HPV, appearing as small bumps that may turn into cauliflower-like masses. Some strains can cause cervical cancer.
Parasitic Infections
- Pubic Lice: Transmitted through sexual activity or the use of contaminated clothing and tools, causing severe itching due to blood absorption from the body.
STI Symptoms and Diagnosis
An infected person may not show any signs, but the most prominent STI symptoms include:
- Ulcers, warts, or growths in the genital area, anus, or mouth.
- Abnormal discharge from the vagina or penis with an unpleasant odor.
- Itching or burning in the genital area, or pain during urination or bowel movements.
Diagnosis is performed through medical history and a detailed physical examination of the affected areas, in addition to laboratory tests such as blood tests, urine samples, and fluid swabs from ulcers or the cervix.
STI Treatment and Prevention
The approach to STD treatment varies depending on the cause:
- Bacterial and Parasitic Infections: Usually treated with antibiotics or specialized medications.
- Viral Infections: There is no complete cure for these; medications are used to control symptoms and improve quality of life.
Methods of STI treatment and prevention:
- Commitment to marital relations and abstinence.
- Correct use of condoms, avoiding oil-based lubricants as they weaken the material.
- Urinating and washing the genital area with soap and water after intercourse.
- Avoiding sex during menstruation or the use of vaginal douching.
- Abstaining from intravenous drug use.
When to Visit a Doctor?
You should immediately consult a specialist in the following cases:
- Appearance of any ulcers, warts, or abnormal discharge in the genital areas.
- Feeling unusual burning or pain during urination.
- When starting a new sexual relationship or before marriage for routine screenings.
- If a woman is pregnant, as the infection can be transmitted from mother to infant, causing serious health problems for the fetus.
