Comprehensive Guide to Sexually Transmitted Diseases (STDs) and Prevention in Turkey
Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), are among the most common infectious conditions affecting adults worldwide. They are primarily spread through sexual contact—vaginal, anal, or oral—but may also be transmitted from mother to child during birth, breastfeeding, or through contaminated blood. According to the World Health Organization (WHO, 2024), over one million new infections occur daily. In Istanbul and other major Turkish cities, gynecologists and infectious disease specialists report a growing number of asymptomatic STIs, highlighting the importance of routine screening and early treatment.

STIs affect both men and women, but women face greater risks of long-term complications such as pelvic inflammatory disease (PID), infertility, and chronic pelvic pain. Istanbul-based gynecology clinics emphasize prevention, vaccination, and regular testing to ensure reproductive health and protect public well-being.
Most Common Types of STIs in Istanbul
1. Chlamydia (Chlamydia trachomatis)
Chlamydia is one of the most reported infections among sexually active young adults in Turkey. Many patients show no symptoms, which allows silent transmission. Typical signs include abnormal discharge, burning during urination, and pelvic pain. Untreated cases can cause PID or infertility.
UpToDate (2025) and PubMed studies (PMID: 38361722, 2024) confirm doxycycline as the most effective treatment. Istanbul clinics recommend annual screening for sexually active women under 25.
2. Gonorrhea (Neisseria gonorrhoeae)
Gonorrhea remains a public health concern due to antibiotic resistance. It affects the cervix, urethra, rectum, and throat. Co-infection with chlamydia is common.
WHO and Turkish Ministry of Health guidelines recommend ceftriaxone injection as the primary therapy. Patients in Istanbul are advised to avoid unverified antibiotic use, which worsens resistance patterns.
3. Human Papillomavirus (HPV)
HPV is the most common viral STI globally and in Turkey. Certain high-risk types cause cervical and anal cancers, while others produce genital warts.
In Istanbul, gynecology clinics provide HPV vaccination (Gardasil 9®), cervical smear tests, and HPV typing. According to UpToDate, vaccination before sexual activity can prevent up to 90% of HPV-related cancers.
4. Herpes Simplex Virus (HSV-1 and HSV-2)
Herpes causes painful blisters around the genital or oral area. HSV-1 is often oral, while HSV-2 is genital. Once infected, the virus remains latent in nerve tissue and may reactivate.
Treatment involves antivirals like acyclovir or valacyclovir. Turkish clinicians emphasize that even during symptom-free periods, transmission is possible. Istanbul sexual health centers provide discreet herpes management and counseling.
5. Syphilis (Treponema pallidum)
Syphilis cases have increased in Europe and Turkey in recent years. The infection progresses through stages—from an initial painless sore to rashes and systemic complications.
Early diagnosis using blood tests (VDRL, TPHA) is essential. Penicillin remains the gold-standard treatment. In Istanbul, private and state clinics offer same-day syphilis testing and treatment with confidentiality.
6. Hepatitis B and C
These viral infections are transmitted through sexual contact or blood exposure. Chronic hepatitis can lead to cirrhosis and liver cancer.
Hepatitis B vaccination is part of Turkey’s national immunization program. For hepatitis C, modern antiviral medications can cure the infection completely. Istanbul hospitals provide comprehensive screening and follow-up programs for high-risk patients.
7. Human Immunodeficiency Virus (HIV)
HIV attacks the immune system and can progress to AIDS if untreated. With early antiretroviral therapy (ART), patients lead long, normal lives.
In Istanbul, specialized HIV centers provide confidential testing and treatment. “U=U” (Undetectable = Untransmittable) campaigns are promoted to reduce stigma and encourage early treatment initiation.
8. Trichomoniasis (Trichomonas vaginalis)
A parasitic infection that causes vaginal discharge, itching, and discomfort in women, and mild urethritis in men. It is treated with metronidazole or tinidazole.
Since reinfection is common, both partners should be treated simultaneously. Istanbul clinics often provide couple consultations to ensure effective management.
Typical Symptoms of STIs
Common signs include abnormal discharge, pelvic pain, burning during urination, painful intercourse, genital sores, or rashes. However, more than 60% of infections are asymptomatic, especially in women.
In Istanbul, most gynecology clinics recommend routine STI screening at least once a year or after unprotected sexual contact.
Diagnosis and Testing in Istanbul
Modern diagnostic technologies used in Istanbul include:
-
PCR and NAAT tests for chlamydia, gonorrhea, trichomonas.
-
Serologic blood tests for HIV, syphilis, hepatitis B/C.
-
Pap smear and HPV DNA testing for cervical cancer prevention.
-
Culture and PCR swabs for herpes confirmation.
UpToDate (2025) stresses that early and combined testing significantly reduces disease transmission and complications. Many Istanbul clinics offer same-day test results with confidentiality and rapid therapy options.
Treatment and Medical Management
Bacterial infections are curable, while viral infections can be controlled with long-term antiviral therapy.
-
Chlamydia: Doxycycline 100 mg twice daily for 7 days.
-
Gonorrhea: Ceftriaxone 500 mg single IM dose.
-
Syphilis: Benzathine penicillin G.
-
Trichomoniasis: Metronidazole 2 g single dose.
-
Genital Herpes: Valacyclovir or acyclovir for outbreak control.
-
HIV: Triple combination ART for viral suppression.
-
Hepatitis: Antiviral therapy to prevent liver damage.
Partner testing and treatment are crucial to prevent reinfection. Patients are advised to abstain from intercourse until the therapy is completed. In Istanbul, clinics prioritize privacy and same-day initiation of therapy.
Complications of Untreated STIs
Untreated infections may cause severe outcomes:
-
Infertility and ectopic pregnancy due to fallopian tube damage.
-
Cervical and liver cancers from HPV and hepatitis.
-
Chronic pelvic pain and PID.
-
Neurological damage from syphilis.
-
Increased HIV susceptibility.
-
Complicated pregnancies and neonatal infections.
In Istanbul’s busy metropolitan population, delayed diagnosis often results from embarrassment or misinformation. Public health campaigns and gynecology specialists now emphasize education and destigmatization to improve outcomes.
Prevention and Safe Practices
Prevention remains the most powerful tool:
-
Condom use in all sexual encounters.
-
HPV and Hepatitis B vaccination for adolescents and unvaccinated adults.
-
Regular screening after new or multiple partners.
-
Avoid sharing needles or personal items.
-
Mutual monogamy and honest communication between partners.
-
PrEP (pre-exposure prophylaxis) for individuals at high HIV risk.
In Istanbul, many private clinics and hospitals now provide vaccination and rapid test programs integrated into gynecologic checkups. According to PubMed reviews (2025), preventive gynecologic care is the most cost-effective approach in urban populations.
