Which STDs Are Curable and Which Are Manageable?

Quick answer
Bacterial and parasitic STIs are curable: chlamydia, gonorrhea, syphilis, and trichomoniasis. Viral STIs are manageable but not curable: HIV, herpes, HPV, and hepatitis B. Hepatitis C is the exception, with about 95% of people cured by 8 to 12 weeks of oral antivirals.
Which STDs are curable?
The dividing line is biology. Bacterial and parasitic STIs are curable with antibiotics or antiparasitic drugs, while viral STIs are managed rather than cured because the virus persists in the body. Hepatitis C is the notable exception among viruses. Here is the full breakdown:
| Type | Infection | Status |
|---|---|---|
| Bacterial | Chlamydia | Curable |
| Bacterial | Gonorrhea | Curable |
| Bacterial | Syphilis | Curable |
| Parasitic | Trichomoniasis | Curable |
| Viral | HIV | Manageable, not curable |
| Viral | Herpes (HSV) | Manageable, not curable |
| Viral | HPV | Manageable; ~90% clear on their own |
| Viral | Hepatitis B | Manageable, not curable |
| Viral | Hepatitis C | Curable (~95% with DAAs) |
How are curable STDs treated?
Chlamydia is cured with azithromycin 1 gram as a single dose or doxycycline for 7 days, and the CDC recommends retesting at 3 months because reinfection is common. Gonorrhea is treated with the CDC 2021 and later dual therapy of ceftriaxone 500 mg intramuscular plus doxycycline for 7 days. Trichomoniasis is cured with a single dose of metronidazole or tinidazole, and partners should be treated too. Syphilis is cured with penicillin, staged by how long the infection has lasted.
Why can't viral STDs be cured?
Viruses integrate into your cells or hide in your body in ways antibiotics cannot reach. HIV is not curable, but antiretroviral therapy (ART) makes it manageable, and undetectable means untransmittable when viral load is under 200 copies per mL. Herpes is not curable, but antivirals suppress outbreaks. HPV usually clears on its own within two years. Hepatitis B is manageable, and a vaccine prevents it. The goal shifts from cure to long-term control.
Is hepatitis C really curable?
Yes, and it is the major exception among viral STIs. About 15 to 25% of people clear hepatitis C spontaneously, and of those who do not, roughly 95% are cured with 8 to 12 weeks of oral antivirals called DAAs. The antibody test becomes reliable 8 to 9 weeks after exposure, while RNA testing detects the virus in 1 to 2 weeks. A cure is confirmed when the virus stays undetectable after treatment.
What does curable versus manageable mean for me?
It changes the goal of treatment and testing. Curable infections need complete treatment, partner treatment, and a retest to confirm the cure. Manageable infections need ongoing monitoring, suppression, and prevention of transmission. Either way, knowing your status is the first step. A comprehensive STD panel plus hepatitis testing tells you which category you are dealing with.

Frequently asked questions
Can herpes ever be cured?
No. Herpes is not curable, but antiviral medications suppress outbreaks and reduce transmission by about 50 to 70%.
Is HIV curable?
No, but antiretroviral therapy makes it manageable. Undetectable viral load means the virus cannot be transmitted.
