Can You Have an STI Without Symptoms?

One of the most dangerous myths about sexual health is the belief that you’ll always know if you have a sexually transmitted infection (STI). The truth is, many STIs cause no symptoms at all, and that’s exactly how they spread so easily.

In fact, you could feel perfectly healthy and still carry an infection that puts your long-term health and your partner’s wellbeing at risk.

The Silent Nature of STIs

Studies show that the majority of people with Chlamydia have no symptoms. The same is true for many cases of Gonorrhoea. Even more concerning, infections like HIV and Syphilis can remain hidden for weeks, months, or even years before noticeable signs appear.

This “silent” stage doesn’t mean the infection is harmless, it simply means you won’t realise it’s there until complications develop.

Common STIs That Often Have No Symptoms

Chlamydia – Often symptomless but can cause infertility if untreated.
Gonorrhoea – May not show signs, particularly in women.
Syphilis – Early sores may disappear on their own, but the infection continues silently.
HIV – Can remain unnoticed until the immune system is weakened.
HPV (Human Papillomavirus) – Most types cause no visible signs, but some can lead to cancer.
Herpes (HSV) – Some people carry the virus without ever experiencing outbreaks.

Why This Matters

When STIs go undetected:

They can cause long-term complications such as infertility, pelvic inflammatory disease, chronic pain, and organ damage.
They increase the risk of transmitting HIV.
They can be passed unknowingly to partners.

Testing is the only way to break the cycle.

Signs to Watch For

Even though many STIs have no symptoms, there are times when you should be especially alert:

Unusual discharge
Pain or burning when urinating
Sores, rashes, or blisters in the genital area
Bleeding between periods or after sex
Pain during sex
Sore throat after oral sex

But remember: the absence of these signs doesn’t mean you’re clear.

👉 Stay safe. Arrange your STI screen at STI Clinic.

How Often Should You Get Tested?

If you’re sexually active, especially with new or multiple partners, you should be tested regularly - even if you feel fine. General guidance suggests:

Every 6–12 months if you’re sexually active
More often if you have new partners or engage in higher-risk activities
Immediately if you’ve had unprotected sex and are concerned about exposure

Routine testing is a normal part of looking after your health.
