Sexually transmitted diseases (STDs) and sexually transmitted infections (STIs) are caused by the transfer of bacteria, viruses, or parasites during unprotected sex.
Every STD has a different incubation period—in other words, they vary in the amount of time it takes for symptoms to show. While the incubation period for some STDs is as short as a few days or weeks, other STDs can lie dormant for years.
A dormant sexually transmitted disease is a disease or infection that exists within the body without triggering STD symptoms. And while a dormant STD may not display visible signs or cause any discomfort, you can still spread it to your sexual partner or partners.
So, how long can an STD stay dormant without symptoms? Today, we’re answering this question by looking at the various STDs that can lie dormant, how long they can stay dormant, and how you can find out if you’re affected.
Which STDs can stay dormant?
Several of the more than 20 types of STDs can lie dormant for months, years, or even decades. Dormant STDs and STIs highlight the importance of sexual health testing, as only a test can determine if an asymptomatic infection is present.
Here are four of the most common STDs that can stay dormant.
HIV (10+ years)
Human immunodeficiency virus (HIV) is one of the most well-known examples of an STD that can lie dormant.
The first stage of HIV is called an acute HIV infection, which can cause flu-like symptoms within 2 to 4 weeks of infection.[1] Common STD symptoms include:
- Chills
- Fever
- Rash
- Sore throat
- Fatigue
Because these symptoms are related to dozens of illnesses, people infected with HIV may not know they have the virus. At that point, HIV can progress to its second stage.
When HIV reaches its second stage—the stage known as an asymptomatic HIV infection, chronic HIV infection, or clinical latency—it continues to multiply within the body without showing symptoms. For some, this dormant stage can last for more than ten years.[2]
During this stage of HIV, the immune system may slowly weaken, but otherwise, the virus does not affect the body. The only way to detect HIV at this stage is to take an HIV test. Testing is important because if the virus remains undetected and untreated, it can progress to AIDS (acquired immunodeficiency syndrome).[3]
Chlamydia (1+ years)
Chlamydia trachomatis can be exceptionally tricky to notice, as you’re more likely to be an asymptomatic carrier than a symptomatic carrier. Estimates claim that only 10% of men and 5–30% of women will develop chlamydia symptoms. Chlamydia is frequently asymptomatic and may persist for months or longer without noticeable symptoms.[4]
Because people infected with chlamydia often show no symptoms, it’s sometimes called a “silent” infection. However, even when chlamydia is asymptomatic, it can spread during unprotected vaginal, oral, or anal sexual contact. Taking a chlamydia test can inform you if you have chlamydia—and whether you’re asymptomatic or not.
Once again, STD testing is essential. Even if you don’t experience symptoms, untreated chlamydia can lead to health complications.
Syphilis (30+ years)
Syphilis has an unusual progression in that it can become dormant after a period of recognizable symptoms. There are four stages of syphilis:
- Primary stage – Syphilis can appear as sores (chancres) within 10–90 days of infection. These often resolve within 3–6 weeks.
- Secondary stage – Without treatment, rashes and lesions may appear before symptoms disappear again.
- Latent stage – Syphilis can remain dormant for more than 30 years without symptoms.[6]
- Tertiary stage – Can damage internal organs if untreated.
You can use an at-home test to detect syphilis at any stage.
HPV (dormancy period unknown)
HPV is the most common STD. It often has no symptoms, though some strains cause genital warts. Most cases resolve within 1–2 years.[7]
However, HPV can lie dormant for years. Research suggests it may reactivate even decades after infection.[8]
The HPV vaccine protects against several high-risk strains, though more research is needed to define exact dormancy timelines.[9]
When it comes to UTI vs. STD, early testing and treatment is critical.
