What STDs Have No Symptoms?

What STDs Have No Symptoms
Published:  May 19, 2025

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are often associated with noticeable symptoms like pain, discharge, or sores. However, many STDs can go unnoticed for months or even years. This is why regular STD testing is essential, even if you feel healthy. In this article, we’ll cover common asymptomatic STDs, why they go undetected, and when you should consider getting tested.

Can You Have an STD Without Symptoms?

Yes. Many STDs can remain asymptomatic, meaning they cause no noticeable symptoms but can still be transmitted to others. Even without STD symptoms, these infections can lead to serious health complications over time.

Which STDs Can Have No Symptoms?

Several STDs may not show symptoms right away—or ever. Below are some of the most common asymptomatic STDs:

Chlamydia

Chlamydia is one of the most frequently reported STDs in the U.S., yet most people never experience symptoms. When STI symptoms do appear, they may include burning during urination, unusual discharge, or pelvic pain. If left untreated, chlamydia can lead to pelvic inflammatory disease (PID) in women and infertility in both men and women.

Gonorrhea

Gonorrhea can infect the genitals, throat, or rectum, often without symptoms. When symptoms occur, they may include painful urination, abnormal discharge, or sore throat. Untreated gonorrhea can cause severe reproductive health issues and increase the risk of HIV transmission.

Human Papillomavirus (HPV)

HPV is the most common STD, and many strains cause no symptoms at all. Some strains lead to genital warts, while others increase the risk of cervical, anal, or throat cancer. Routine pap smears and HPV vaccinations can help prevent complications from high-risk HPV strains.

Herpes (HSV-1 & HSV-2)

Many people with oral or genital herpes have no idea they are infected. The virus can remain dormant for years, with occasional outbreaks of painful blisters. Even without visible sores, herpes can still be transmitted through skin-to-skin contact.

HIV

HIV often has no early symptoms, making it one of the most dangerous undetected infections. Some people experience flu-like symptoms within weeks of exposure, but many remain symptom-free for years. Without treatment, HIV can progress to AIDS, severely weakening the immune system.

Trichomoniasis

Trichomoniasis, a common but often overlooked STD, affects both men and women. 70% of infected individuals have no symptoms, though some may experience itching, burning, or unusual discharge. If untreated, trichomoniasis can lead to an increased risk of other infections and pregnancy complications.

How Long Can STDs Be Dormant?

Here’s how long some of the most common STDs can stay dormant before symptoms appear—or never appear at all:

STD Dormancy Period Symptoms May Never Show?
Chlamydia Weeks to months Yes, ~70% of women & 50% of men have no symptoms
Gonorrhea Weeks to months Yes, many cases are mild or asymptomatic
HPV Months to years Yes, most infections clear on their own
Herpes (HSV-1 & HSV-2) Months to years Yes, some people never experience outbreaks
HIV Several years Yes, it may not show symptoms for 5-10 years
Syphilis Months to decades Yes, after the initial sore heals, it can remain hidden
Trichomoniasis Weeks to months Yes, ~70% of cases are asymptomatic

When Should You Get Tested for STDs?

Even if you feel healthy, you should consider routine STD testing if you:

  • Are sexually active with new or multiple partners
  • Have had unprotected sex
  • Are experiencing burning, itching, or unusual discharge
  • Are planning a pregnancy
  • Have a partner who was recently diagnosed with an STD

The CDC recommends annual screening for chlamydia, gonorrhea, and HIV for sexually active individuals under 25 or those at higher risk.

How STIs Are Diagnosed

Primary care providers use various diagnostic methods depending on the type of STI, symptoms, and risk factors. Here is an overview of how different STIs are diagnosed, when to get tested, and the window period—the time it takes after exposure for a test to detect a sexual infection accurately.

STI Testing Method When to Get Tested Window Period
Chlamydia Urine test or swab
(vaginal, cervical, urethral,
or rectal)
If you have symptoms, or 3-5 weeks after exposure 1-2 weeks
Gonorrhea Urine test or swab
(vaginal, cervical, urethral,
rectal, or throat)
If you have symptoms, or 3-5 weeks after exposure 1-2 weeks
HPV
(Human Papillomavirus)
Pap smear (for high-risk strains)
or HPV DNA test
Routine screening every 3-5 years for women Months to years
Herpes
(HSV-1 & HSV-2)
Swab test of sores, blood test
(if no symptoms)
If you have symptoms (sores) or 12+ weeks
after exposure for blood test
4-12 weeks
HIV Blood test
or rapid oral swab
2-4 weeks after exposure,
with follow-up at 3 months
10-33 days
Syphilis Blood test
or swab of sores if present
3-6 weeks after exposure 3-6 weeks
Trichomoniasis Urine test or vaginal swab If you have symptoms, or 3-4 weeks after exposure 1-4 weeks

Do STDs Go Away on Their Own?

No, STDs do not go away on their own, and leaving them untreated can lead to serious health complications. While some infections may not cause noticeable symptoms, the underlying infection remains in the body and can be transmitted to others. 

  • Bacterial STDs, such as chlamydia, gonorrhea, and syphilis, require antibiotics to be fully cured, while parasitic infections like trichomoniasis need prescription medication. 
  • Viral STDs, such as herpes, HIV, and HPV, cannot be cured, but medical treatment can help manage symptoms and reduce transmission risks.

Even if the STD symptoms disappear, the infection may still be active and cause long-term health problems, including infertility, chronic pain, organ damage, or increased risk of other types of infections. Routine STD screening ensures early detection and helps prevent complications.
