Quick Answer

Eight STIs are fully curable with antibiotics or antiparasitics: chlamydia, gonorrhea, syphilis, trichomoniasis, pubic lice, scabies, molluscum contagiosum, and mycoplasma genitalium. Four remain incurable but manageable: HIV, herpes, HPV, and hepatitis B — though hepatitis C, once incurable, now clears in over 95% of cases with modern antivirals.

  • Bacterial STIs cure completely when treated — no residual infection, no chronic carrier state.
  • Hepatitis C transformed: direct-acting antivirals since 2014 cure what was previously lifelong.
  • HPV mostly self-clears within 1–2 years; persistent strains are managed through monitoring.
  • HIV and herpes lack cures but modern suppression renders both transmission-fragile and symptom-light.

The Landscape

Curability follows organism biology: bacteria and parasites die when antibiotics disrupt their specific machinery. Viruses integrate into host cells or hide in ganglia — clearing them means clearing your own tissue, which medicine hasn't solved for these four.

Fully curable

  • Chlamydia
  • Gonorrhea
  • Syphilis
  • Trichomoniasis
  • Pubic lice ("crabs")
  • Scabies

Treatable, not curable

  • HIV — daily antiretroviral therapy (ART) that can make the virus undetectable
  • Genital herpes (HSV) — antivirals such as acyclovir or valacyclovir to shorten outbreaks or suppress them
  • HPV (human papillomavirus) — no virus-killing drug; warts and abnormal cells are treated directly, and most infections clear naturally within 1–2 years
  • Hepatitis B — antivirals for chronic infection; a highly effective vaccine prevents it
  • Hepatitis C — modern direct-acting antivirals cure over 95% of people in 8–12 weeks

Cured ≠ immune

Successful chlamydia treatment grants zero future immunity — reinfection happens immediately upon re-exposure. Cure addresses this infection, not all infections.

The hepatitis C lesson

Medical dogma said incurable until 2014; science moved. People living with 'incurable' labels today should track research — therapeutic vaccines and gene-editing approaches target HIV and herpes actively.

Treatment Windows by Infection

Bacterial infections clear with antibiotics measured in days: a single 500 mg intramuscular ceftriaxone dose for gonorrhea (doxycycline is added only if chlamydia has not been ruled out), seven days of doxycycline for chlamydia, penicillin injections for syphilis staged by duration. Viral infections play a longer game — suppressive antivirals for herpes, daily ART driving HIV to undetectable, and 8–12-week antiviral courses curing over 95% of hepatitis C cases.
