If you are sexually active within Belgium, routinely testing for STIs and STDs is a proactive way to ensure both your wellbeing and that of your partner(s).
These screenings help prevent issues down the line, uncover infections that might still be asymptomatic, and promote a responsible attitude towards safe sex.
However, figuring out where to go, which tests are relevant, and whether insurance coverage applies can be confusing, especially given Belgium’s bilingual healthcare system.
That’s where we come in.
In this guide, you’ll learn:
By the end, you’ll understand exactly how to care for your sexual health while living in or visiting Belgium.
Let’s get into it!
It’s important to understand that many STIs don’t produce early symptoms.
Whilst some infections do show physical signs, viruses such as HPV, HIV, and hepatitis B can remain hidden for months, which underscores the importance of routine testing to catch infections early.
Never attempt self-diagnosis.
When in doubt, testing remains the most reliable approach. Conditions like yeast infections, skin irritations, or urinary issues can cause similar symptoms to STIs.
You should consider testing if you show any of the following symptoms:
| Infection | Typical signs (may vary) | Timeframe for symptoms |
|---|---|---|
| Chlamydia | Discharge, burning sensation during urination, testicular discomfort | 1–3 weeks |
| Gonorrhea | Purulent, yellow or greenish discharge, pain while urinating | 1–10 days |
| Genital herpes | Painful blisters or open sores on genitals or anus | 2–14 days |
| Syphilis | Painless sore (chancre), then rashes or flu-like symptoms | 3 weeks to 3 months |
| HPV | Warts, often painless, on the genitals | Weeks to months |
| Trichomoniasis | Frothy vaginal discharge, odor, discomfort during sex | 5–28 days |
| HIV | Fever, fatigue, sore throat, muscle aches | 2–4 weeks |
| Hepatitis B/C | Nausea, skin/yellow eyes jaundice | 6 weeks to 6 months |
Following a risky encounter or potential exposure, consult a healthcare provider. They can advise you about the best timing for testing and whether repeated tests are advisable.
Generally, if you suspect exposure, it’s best to proceed with testing. The only thing to keep in mind is the importance of timing.
This is because many infections have a “window period” during which they are not yet detectable. Testing too early may lead to false negatives, missing an ongoing infection.
Here’s an overview of typical window periods:
| Disease | Earliest accurate detection | Testing method |
|---|---|---|
| HIV | 2–4 weeks (most reliable at 6 weeks) | Blood test detecting antigens and antibodies |
| Chlamydia | 1–2 weeks | Urine test or swab sample |
| Gonorrhea | 1–2 weeks | Urine test or swab sample |
| Syphilis | 3–6 weeks | Blood analysis |
| Hepatitis B/C | 4–6 weeks | Blood analysis |
| Herpes (HSV) | 2–12 weeks (if symptomatic or at high risk) | Blood test or lesion swab |
If the HIV exposure was less than 72 hours ago, immediate measures are necessary, which are detailed below.

Receiving a positive diagnosis can be distressing, but effective treatments and support systems are well-established across Belgium.

If you’re worried or uncertain, Belgium offers extensive support options:
Your medical data is protected by strict privacy standards under GDPR and Belgian confidentiality laws.
Employers cannot access your test results, and disclosure of your STI status is optional unless required for specific public health obligations.
You can opt for anonymous testing at many centers, where neither your name nor ID are recorded, and you receive a pseudonym or code to access your results.
If you want your testing to be reimbursed by your health insurer (mutuelle), however, results will be linked to your identity.
Many testing options in Belgium are free or heavily subsidized, especially at public centers and family planning clinics.
Here’s what you need to know:
If you experienced a high-risk incident, such as unprotected sex with an HIV-positive partner or a needlestick injury, urgent intervention is essential.
