Quick Answer
Rarely. Trichomoniasis occasionally clears spontaneously (~10-20% of cases), HPV clears naturally within 1–2 years in most people thanks to immune response, and molluscum resolves over months. But chlamydia, gonorrhea, syphilis, HIV, herpes, and hepatitis persist indefinitely without treatment — silently causing damage meanwhile.
- Waiting lets treatable infections climb upward: chlamydia toward tubes, syphilis toward brain.
- HPV's natural clearance is real but unpredictable — high-risk strains persisting past 2 years need monitoring.
- Syphilis 'disappears' deceptively: the chancre heals while treponemes disseminate systemically.
- Immune systems contain but don't eradicate herpes and HIV — suppression requires medication.
The Landscape
Self-resolution stories usually describe one of three phenomena: immune clearance (HPV warts), stage transitions masquerading as cure (syphilis), or symptom fluctuation mistaken for elimination (herpes). None represent verified eradication without testing.
The cost of waiting
Every untreated month compounds risks: PID infertility, neurosyphilis, neonatal transmission, onward spread to partners. Antibiotics cost less than consequences by orders of magnitude.
When observation is legitimate
New HPV infections without lesions warrant monitoring rather than immediate intervention — there's no virus-killing drug anyway. Everything else curable deserves actual curing.
Treatment Windows by Infection
Bacterial infections clear with antibiotics measured in days: single-dose azithromycin or a ceftriaxone shot for gonorrhea, 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.
