HIV Incidence Rising in Bangkok – Thailand is projected to record 7,991 to 9,000 new HIV infections in 2026 — a number that has barely moved in five years despite a national target of under 1,000 a year — and people aged 15 to 24 now make up roughly a third to half of new cases in provinces from Bangkok to Chiang Mai.

That gap between target and reality is exactly what PrEP (pre-exposure prophylaxis) exists to close: a prevention medication, taken daily or as a bimonthly injection, that reduces the risk of getting HIV from sex by up to 99% when used correctly. It’s available same-day in Bangkok, and this article covers what the current data shows and how to start.
How Common Is HIV in Thailand in 2026?
According to Thailand’s HIV Info Hub, an estimated 557,993 people were living with HIV in the country as of 2026. New infections are projected at 7,991 to 9,000 for the year — a slow decline from the roughly 10,000-a-year pace of previous years, but still far short of the national strategy’s target: fewer than 1,000 new infections annually. For the past five years, that figure has held steady in the 8,000–9,000 range regardless of the target on paper.
Thirteen provinces account for over half of all cumulative cases nationwide — roughly 285,393 people. Bangkok leads with 88,535 cases, followed by Chonburi (31,072) and Chiang Mai (23,949). But cumulative case counts and new infections tell different stories, and that difference is the whole point of prevention: cumulative cases are everyone currently living with HIV, while new infections are this year’s additions — the number PrEP is designed to bring down.
Why Youth Aged 15–24 Are Driving New HIV Infections — Not Just in Bangkok
This is the shift that should change how anyone under 30 in Thailand thinks about their own risk. Government data cited by AIDS Healthcare Foundation Thailand’s “Just Use It” campaign showed that people aged 15–24 account for more than a third — 35% — of all newly reported HIV infections nationwide. This isn’t a Bangkok-specific trend: Chiang Mai’s Provincial Public Health Office reports an even higher share locally, with 49% of the province’s roughly 700–723 new HIV cases a year occurring in the same 15–24 age bracket — an average of almost two new infections a day in that province alone.
Officials in both cities point to the same drivers: changing sexual behaviour, inconsistent condom use, low awareness of prevention options like PrEP, and limited access to youth-friendly sexual health services. The pattern holds across the 13 provinces carrying the heaviest case load — this is a national youth trend, not a single-city problem, which is why PrEP access needs to be as easy in Chiang Mai, Chonburi, and Pattaya as it is in Bangkok.
The 50,000 People in Thailand Who Don’t Know They Have HIV
Behind the case counts sits a harder number: an estimated 50,000 people in Thailand are living with HIV without knowing it. Untreated, HIV progresses over five to ten years to AIDS, at which point opportunistic infections such as tuberculosis follow and treatment becomes considerably more difficult and expensive. Modern treatment turns an HIV diagnosis into a manageable long-term condition — but only if it’s caught early.
This is the other half of the prevention picture alongside PrEP: regular HIV testing, ideally every three to six months for anyone sexually active with new or multiple partners, closes the gap between infection and diagnosis before it has years to widen.
What Is PrEP and Why Is It Thailand’s Most Effective HIV Prevention Tool?
PrEP is medication taken by HIV-negative people to prevent infection before it happens — different from PEP (post-exposure prophylaxis), an emergency 28-day course started within 72 hours after a possible exposure. Two forms are available in Thailand:
- Daily oral PrEP — one tablet a day, highly effective when taken consistently
- Injectable PrEP — given every two months, with a six-monthly option becoming available, removing the need for a daily pill entirely
Thailand’s Department of Disease Control now recognises PrEP as a basic service available at any hospital without prerequisites, and access has expanded to roughly 29,000 users across around 300 hospitals and key-population health sites nationwide. That’s real progress — but set against 8,000–9,000 new infections a year, it’s still a fraction of who could benefit.
One rule matters more than any other: you must test HIV-negative before starting PrEP. It’s a preventive medication, not a treatment — someone who is already HIV-positive and takes PrEP risks developing drug resistance that makes future treatment harder to manage. This is exactly why PrEP should always start with a proper consultation and test, not a script picked up without one.
HIV Prevention and Treatment: PrEP, PEP, and Condoms Together
None of these tools work in isolation, and Thailand’s own case data — youth infections rising even after decades of sex education — makes the case for using more than one:
- PrEP for ongoing protection if you have new or multiple partners
- PEP as emergency backup within 72 hours of a specific exposure
- Condoms as the baseline, still inconsistently used — provincial data shows the pattern clearly, with a majority of men who have sex with men in Chiang Mai reporting they meet partners through dating apps, often without prior testing history
- Regular testing, since PrEP and PEP both depend on knowing your status first
What Is the Ministry of Public Health Doing About HIV in Thailand?
Thailand’s Ministry of Public Health, through its Department of Disease Control, has recognised PrEP as a basic service available at any hospital without prerequisites. It has helped expand PrEP access to roughly 29,000 users across some 300 hospitals and key-population sites, and backed a public-private push that has distributed around 260,000 free HIV self-testing kits nationwide. Youth-focused screening drives run with UNICEF, WHO, and UNAIDS reached close to 95,000 young people in a single year, catching over 560 new HIV cases early.
The Ministry has also targeted the youth trend directly — partnering with AIDS Healthcare Foundation Thailand on the “Just Use It” school campaign, and launching a 2024 HIV Response Sustainability Roadmap to keep services funded past 2030. Even so, these programmes haven’t closed the gap: Thailand still logs 8,000–9,000 new infections a year, missing its own target of under 1,000. That’s the gap private clinics with same-day access — like HealthDeliver — help fill.
HIV and TB: Why Preventive Care Still Matters
One consequence of untreated HIV that gets less attention than it deserves: tuberculosis. Thailand is one of the countries the World Health Organization classifies as having the world’s highest TB burden, and TB remains a leading cause of death among people living with HIV. For anyone diagnosed with HIV, asking a clinician specifically about TB screening — not just antiretroviral treatment — is worth raising early. For anyone HIV-negative and starting PrEP, it’s a reminder that prevention now is considerably simpler than treatment later.
How to Start PrEP at HealthDeliver Clinic in Bangkok
Given how much of Thailand’s rising HIV picture concentrates in exactly the demographic most likely to be reading this — sexually active adults under 35 — starting PrEP is a same-day, straightforward process:
- Book a consultation. HealthDeliver Clinic’s PrEP and PEP service covers the required HIV-negative test, a risk discussion with a doctor, and prescription in one visit.
- Choose your format. Daily oral tablets or the injectable option, depending on what fits your routine — your doctor will walk through both.
- Get your prescription filled same-day, in-clinic or via HealthDeliver’s discreet at-home delivery option if you’d rather not visit in person.
- Follow up on schedule — quarterly check-ins are standard for anyone on PrEP, combining a repeat HIV test with a prescription renewal.

Frequently Asked Questions HIV Incidence Rising in Bangkok
Is Thailand high risk for HIV?
Thailand’s overall HIV prevalence is low and new infections have fallen sharply since the 1990s, but the country is still recording 8,000–9,000 new infections a year against a government target of under 1,000 — and that number hasn’t improved meaningfully in five years, concentrated heavily in people aged 15–24.
What percent of Thai people have HIV?
An estimated 557,993 people are living with HIV in Thailand as of 2026, out of a population of roughly 66 million — concentrated disproportionately in 13 provinces, led by Bangkok, Chonburi, and Chiang Mai, which together hold over half of all cumulative cases.
Why is HIV increasing?
New infections aren’t increasing overall — they’re plateaued at 8,000–9,000 a year — but the share among people aged 15–24 is rising, now 35% of new cases nationally and up to 49% in provinces like Chiang Mai. Officials attribute this to changing sexual behaviour, inconsistent condom use, and low awareness of prevention tools like PrEP.
Is Bangkok HIV free?
No. Bangkok has the highest cumulative number of HIV cases of any province in Thailand at 88,535, though it also has the country’s best access to testing, PrEP, and treatment.
Is there a 100% cure for HIV?
No, there is currently no cure for HIV. Modern antiretroviral therapy allows most people living with HIV to reach an undetectable viral load and live a normal lifespan, and PrEP, taken before any exposure, reduces the risk of acquiring HIV by up to 99%.
What age is HIV most common?
New HIV infections in Thailand are increasingly concentrated among people aged 15–24, who account for roughly a third of new cases nationally — and closer to half in provinces like Chiang Mai — alongside adults aged 25–49, who remain the largest group by absolute case numbers.
Does Thailand accept HIV positive immigrants?
Thailand does not require an HIV test for tourist visas or most short-stay visas. Requirements can differ for long-term visas and work permits, so anyone applying for longer-term status should check current requirements directly with the Thai embassy or consulate handling their application.Thailand is projected to record 7,991 to 9,000 new HIV infections in 2026 — a number that has barely moved in five years despite a national target of under 1,000 a year — and people aged 15 to 24 now make up roughly a third to half of new cases in provinces from Bangkok to Chiang Mai.
