Prevention Gaps in Nepal
- HPV vaccination coverage is low — many adults never offered it; adult catch-up still helps up to 45.
- Hepatitis B vaccination is patchy in adults — a vaccine-preventable chronic infection still acquired regularly.
- PrEP awareness is minimal — high-risk individuals rarely know the option exists.
- PEP is time-critical and missed — exposures within 72 hours present late because nobody said "come in now."
- Prevention counseling is rare — the post-treatment "how to avoid next time" conversation is almost never had.
Prevention Is the Smartest Money in Sexual Health
Every STI we treat has a cheaper, easier prevention that came earlier. Chlamydia before condoms and screening; cervical cancer before HPV vaccination; HIV before PrEP; syphilis before condoms and partner testing; hepatitis B before a vaccine that has existed for forty years. The prevention visit is the highest-return visit in all of sexual health care — and the one almost nobody schedules.
A prevention clinic does more than lecture about condoms: it assesses your actual risk and deploys the matching tools — vaccines where eligible, PrEP where warranted, PEP urgently when needed, screening intervals that fit your life, and counseling that is practical rather than moralizing.
This page covers each prevention tool, who it is for, and how a prevention consultation works.
The Prevention Toolkit
HPV Vaccination (Gardasil-9)
Protects against the types behind ~90% of cervical cancer and most warts — for teens and adults through 45 after assessment.
Hepatitis B Vaccination
Three-dose course protecting against a chronic liver-attacking STI — essential for unvaccinated sexually active adults.
HIV PrEP
Daily or on-demand pre-exposure prophylaxis — ~99% effective at preventing sexual HIV acquisition for people at ongoing risk.
HIV PEP
Post-exposure prophylaxis within 72 hours of a risk event — 28 days of medication. Time-critical: do not wait.
Screening Schedules
Risk-matched intervals that catch what prevention missed — the backstop for everything else.
Condoms & risk counseling
Practical barrier strategy — honest about what condoms do and do not protect against.
PrEP: Prevention for People at Ongoing Risk
PrEP is daily (or event-based) antiretroviral taken by HIV-negative people that reduces sexual HIV acquisition risk by ~99% when taken correctly. Candidates include serodiscordant partners, MSM with condomless sex, sex workers, and others with ongoing exposure risk. The pathway: baseline testing (HIV must be confirmed negative, plus renal function), the prescription, and 3-monthly monitoring with repeat HIV testing. We assess eligibility honestly and manage the monitoring rhythm.
PEP: The 72-Hour Emergency Option
Post-exposure prophylaxis is emergency prevention — 28 days of antiretrovirals after a specific risk event (unprotected sex with a positive or unknown-status partner, condom break, assault, needle-stick). It must start within 72 hours and works best within 24. If you are reading this after a recent exposure — do not research further; come in now.
Vaccines That Prevent STIs
- HPV (Gardasil-9): cervical/anal/penile/throat cancer prevention plus most warts — 2–3 doses depending on age; assessable for adults to 45.
- Hepatitis B: 3-dose series — protects against a sexually-transmitted chronic infection for life.
- Hepatitis A: for MSM and other risk groups — fecal-oral but relevant to sexual exposure patterns.
- We review your vaccination history and fill the gaps — the simplest prevention medicine offers.
Risk Counseling That Is Actually Useful
Practical, non-judgemental risk reduction: which acts carry which risks, what condoms do and do not cover (skin-to-skin infections transmit around barriers), how to combine tools (vaccine + condom + screening + PrEP), and how to talk to partners about it. The goal is a plan you will actually use — not a lecture you will ignore.

Frequently Asked Questions
Is it too late for me to get the HPV vaccine?
Possibly not — benefit is assessed by age and exposure history through 45. Many adults still benefit significantly; we evaluate honestly rather than defaulting yes.
Who should consider PrEP?
HIV-negative people with ongoing risk — serodiscordant partners, MSM, sex workers, condomless sex with unknown-status partners. A consultation determines eligibility.
I had a risk exposure last night — what now?
Come in immediately — PEP must start within 72 hours, best within 24. This is genuinely time-critical.
Do condoms protect against everything?
No — excellent for fluid-borne infections (HIV, gonorrhea, chlamydia) but incomplete for skin-to-skin infections (herpes, HPV, syphilis). Layered prevention covers what condoms miss.
I'm already vaccinated — what prevention remains?
Screening schedules, condom strategy, PrEP if risk warrants, and behavior planning — vaccination is one layer of several.
