Quick Answer
Yes — both partners need treatment simultaneously, or reinfection becomes near-certain. Most states support expedited partner therapy (EPT): clinicians prescribe medication for partners without examining them, breaking reinfection cycles efficiently.
- Reinfection rates without partner treatment run 15–30% within months.
- EPT is legal in most U.S. states for chlamydia and gonorrhea specifically.
- Health-department disease intervention specialists notify partners for reportable conditions free.
- Partners may harbor identical infections asymptomatically — 'they feel fine' proves nothing.
The Landscape
Ping-pong dynamics make solo treatment futile: you cure, they reinfect, repeat. Simultaneous treatment collapses the cycle mathematically — which is why EPT exists as public-health policy rather than being left to awkward negotiation.
Delivering the news
Script beats improvisation: 'I tested positive for [X]; the CDC says you need testing/treatment too — here's what worked for me.' Text acceptable; anonymous notification services exist for harder conversations.
Different-infection scenarios
Partners of syphilis/HIV diagnoses need clinical evaluation beyond EPT scope — staged workups, PEP consideration for HIV exposure, serologic staging for syphilis contacts.
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.
