Condition
Sexually Transmitted Infections
Sexually transmitted infections (STIs) are infections passed on through vaginal, anal or oral sex. Some, such as chlamydia, gonorrhoea and syphilis, are bacterial and are treated and cleared with the right antibiotic; others, such as genital herpes and HIV, are viral and are managed with ongoing treatment rather than cleared completely. Many cause no symptoms at first, which is why testing rather than waiting for symptoms is how most are found.
STIs are far from rare: the World Health Organization estimated 376 million new infections of chlamydia, gonorrhoea, trichomoniasis and syphilis worldwide in a single year, roughly one million treatable STIs acquired every day[1]. A large share of these infections cause no symptoms at all, especially in the first weeks, so the number of men carrying an infection unknowingly is higher than diagnosis figures alone suggest. That combination — common, often silent, and readily treated once found — is why routine testing after a new or unprotected partner, together with treating and informing any recent partner so the infection is not passed back and forth, is the standard approach rather than waiting for a symptom[2].
How each system of medicine approaches Sexually Transmitted Infections
| System | Approach | Typical review period |
|---|---|---|
| Modern medicine | Testing first, treatment matched to what is found: a consultation asks about recent partners and symptoms, and a urine test, swab or blood test, depending on what is being checked for, identifies the organism before any antibiotic is prescribed. Treating on symptoms alone risks missing the actual infection or choosing the wrong drug. | Most bacterial infections clear with a single dose or a short course of antibiotic and are usually retested a few weeks later to confirm it worked; viral infections are followed with regular reviews rather than a fixed end point, since the treatment continues. |
Modern medicine for Sexually Transmitted Infections
Bacterial STIs such as chlamydia, gonorrhoea, syphilis and trichomoniasis are treated with a specific antibiotic chosen for that organism, guided for gonorrhoea by local resistance patterns. Viral infections such as genital herpes and HIV are managed with antiviral treatment that controls the virus and greatly lowers the chance of passing it on, even though the virus itself stays in the body[3].
- Antibiotic-treatable infections: chlamydia, gonorrhoea, syphilis and trichomoniasis are all treated and cleared with antibiotics when the right one is chosen and taken as prescribed; treatment guidelines are revised periodically as resistance patterns shift, which is one reason self-treating without a test is discouraged[3].
- Viral infections are managed, not cleared: herpes and HIV remain in the body, but modern antiviral treatment controls symptoms and, for HIV, can lower the amount of virus in the blood so far that the risk of passing it to a partner becomes very low; this page does not overstate what treatment achieves for either.
- Partner notification works: a systematic review of ways to inform a patient's recent partners found that structured approaches, such as a provider contacting the partner or the patient carrying treatment to them directly, led to more partners being tested and treated than simply advising the patient to mention it[2].
- Testing without symptoms: because many STIs are silent early on, testing after a new or unprotected partner is how most infections are actually found, rather than waiting for a symptom that may never appear.

Frequently Asked Questions
Can STIs be treated without a test?
It isn't advisable. Different organisms need different antibiotics, and a symptom alone does not identify which one is present; testing before treatment means the right drug is used and any other infection present at the same time is not missed[3].
Can every STI be treated and cleared?
Bacterial infections such as chlamydia, gonorrhoea, syphilis and trichomoniasis are treated and cleared with antibiotics. Viral infections such as herpes and HIV are not cleared from the body, but they are managed with treatment that controls them well[3].
Do I need to tell my partner?
Yes, and a consultation can help with how. A review of partner notification methods found that structured support, rather than simply being asked to mention it, led to more partners actually being tested and treated[2].
I have no symptoms — do I still need testing?
Often yes. Many STIs cause no symptoms in the weeks after infection, which is exactly why testing after a new or unprotected partner, rather than waiting to feel unwell, is how most infections are actually found.
How common are STIs really?
More common than most people assume: global estimates put new infections of just four treatable STIs at over a million a day[1]. That scale is part of why testing is treated as routine rather than exceptional.
