Many sexually transmitted diseases (STDs) can spread without obvious symptoms, which is why regular testing is so important. Here’s a quick guide to some of the most common STDs in Thailand and what you should know about them.
| STD | Common Symptoms | Can You Have It Without Symptoms? | Possible Risks if Untreated | Prevention & Protection |
|---|---|---|---|---|
| Chlamydia | Pain during urination, unusual discharge, pelvic discomfort | Yes — very common | Infertility, pelvic inflammatory disease (PID), complications during pregnancy | Condoms, regular STI testing, early antibiotic treatment |
| Gonorrhea | Burning when urinating, discharge, sore throat, rectal discomfort | Yes | Infertility, joint infections, increased HIV risk | Condoms, routine screening, prompt treatment |
| Syphilis | Painless sore, rash, fever, swollen lymph nodes | Sometimes | Damage to the brain, nerves, heart, and organs | Safe sex practices, early blood testing, treatment with antibiotics |
| HIV | Flu-like symptoms in early stages or no symptoms at all | Yes | Weakens the immune system over time | Condoms, PrEP, PEP, regular HIV testing |
| HPV | Genital warts or no symptoms | Very common | Certain strains may lead to cervical, anal, or throat cancer | HPV vaccination, condoms, regular screenings |
| Herpes (HSV) | Blisters, sores, itching, tingling sensations | Yes | Recurring outbreaks and possible transmission even without symptoms | Condoms, antiviral medication, avoiding sexual contact during outbreaks |
One of the biggest myths about STDs is that you’ll always know if something is wrong. In reality, many infections can stay silent for months—or even years.
That means someone can feel completely healthy while still passing an infection to partners.
Regular testing helps:

Clinics such as PULSE Clinic provide confidential STI testing, HIV screening, PrEP, PEP, vaccinations, and sexual health consultations for both locals and international visitors in Thailand.
Remember: getting tested is normal, responsible, and one of the easiest ways to take care of your health.
