01 — The short answer
HIV in Pattaya: what the numbers say.
There is no official, current figure for the HIV rate in Pattaya, so any single percentage you read online should be treated with caution.
What does exist is solid national data. According to UNAIDS estimates, about 1 in 100 adults aged 15–49 in Thailand live with HIV, and most of them are on effective treatment. There is also limited survey data for some groups in Chonburi province, which includes Pattaya.
The more useful point is this: your own risk depends on what happened and which prevention you used, not on the name of the city. If you had condomless sex or a condom broke in the last 72 hours, don’t wait for statistics. Ask about HIV PEP in Pattaya today.
02 — Thailand’s numbers
Is HIV common in Thailand? The verified figures.
HIV is present in Thailand at a moderate level, and new infections have roughly halved since 2010.
The figures below are UNAIDS estimates for 2023, published in the UNAIDS Data 2024 country profiles. Estimates are rounded and revised each year as models improve, so treat them as a picture of scale rather than exact counts.
HIV in Thailand: the key numbers
| Measure | Estimate | Year |
|---|---|---|
| People living with HIV | About 580,000 | 2023 |
| Adults aged 15–49 living with HIV | About 1% | 2023–2024 |
| New HIV infections | About 9,100 (18,000 in 2010) | 2023 |
| AIDS-related deaths | About 12,000 (35,000 in 2010) | 2023 |
| People on HIV treatment | About 475,000, roughly 8 in 10 | 2023 |
So the honest answer to “is HIV common in Thailand” is: present, well monitored and falling. The HIV infection rate in Thailand dropped by 49% between 2010 and 2023.
03 — Local data
Is there a Pattaya figure? Not really.
Thailand estimates HIV nationally and runs surveys in selected provinces, but no official source publishes a Pattaya HIV prevalence for the general population.
The closest local data comes from surveys among specific groups. The AIDS Data Hub Thailand snapshot reports that in 2020 about 8% of transgender people surveyed in Chonburi were living with HIV, compared with 4.2% across four survey sites. That tells you something about one community’s needs, not about the whole city.
What the data can and can’t tell you
| Type of data | What it shows | What it can’t show |
|---|---|---|
| National estimates | Scale and trends across Thailand | Differences between cities |
| Province surveys of key groups | Where one group needs more support | The rate for residents or visitors overall |
| Clinic or hospital caseloads | Who came in for testing | How common HIV is in the population |
| Your own exposure | Your real, personal risk | Nothing about anyone else |
04 — Scary headlines
Why “30%” claims don’t hold up.
Some articles say a huge share of people in Pattaya have HIV, but these claims rarely say who was counted or how.
One widely shared story quoted “about 30%” without saying 30% of what. A figure like that usually describes patients already attending an HIV service, where you would expect many positive results. It is not a population rate, and presenting it as one spreads fear and stigma.
Myths vs facts about HIV in Pattaya
| Myth | Fact |
|---|---|
| A third of Pattaya has HIV | No official source supports this; national adult prevalence is about 1% |
| HIV is rising fast in Thailand | New infections fell by about half between 2010 and 2023 |
| Being in Pattaya is itself the risk | Risk comes from specific exposures, wherever they happen |
| You can tell who has HIV | You can’t; testing is the only way to know |
The Pattaya HIV rate you see on forums is usually an opinion, an old number or a misread statistic.
05 — Who is affected
Key populations, without the stigma.
In Thailand, as in most countries, HIV is more common in some communities, mainly because of barriers to prevention and care.
Surveys summarised by the AIDS Data Hub found higher levels among gay and bisexual men, transgender people and people who inject drugs. In 2020, about 7.3% of men who have sex with men surveyed across three sites had HIV, while the national survey figure for female sex workers was about 1.1%.
These numbers describe networks and access to services, not anyone’s worth or character. Higher figures are also why prevention programmes, PrEP and testing are focused on these communities. Stigma keeps people away from testing, which is exactly what helps HIV spread.
06 — Your real risk
HIV risk in Pattaya depends on the encounter.
Your personal risk comes down to three things: the type of exposure, your partner’s HIV status and treatment, and the prevention you used.
- Type of exposure. Condomless anal sex carries a higher risk than vaginal sex; oral sex carries a very low risk.
- Your partner’s status. Someone living with HIV who has an undetectable viral load on treatment does not pass HIV on through sex (U=U).
- Prevention used. A condom used correctly, or PrEP taken as prescribed, protects you very well.
That is why the HIV risk in Pattaya is the same as in any other city for the same encounter. If a condom broke, read what to do if a condom breaks and act within hours.
07 — Progress
HIV in Pattaya in 2026: a country that treats it well.
Thailand has one of the stronger HIV responses in Asia, and that shapes the picture for anyone looking at HIV in Pattaya in 2026.
UNAIDS reports that more than 80% of people living with HIV in Thailand were on treatment in 2023, and about 465,000 had a suppressed viral load. AIDS-related deaths fell by 65% since 2010. More people on effective treatment means fewer onward infections.
PrEP is also growing: about 27,000 people received it at least once in 2023, up from roughly 15,000 in 2022. If you are staying a while or visit often, PrEP in Pattaya is worth a conversation.
08 — Prevention
Your prevention toolkit, whatever the statistics.
Four tools cover almost every situation, and you can combine them.
Your prevention options compared
| Option | When you use it | What it does |
|---|---|---|
| Condoms | Every time you have sex | Protect against HIV and many other STIs |
| PrEP | Before and during periods of possible exposure | Prevents HIV when taken as prescribed |
| PEP | Within 72 hours after an exposure | Greatly reduces the chance of infection |
| Testing | Regularly, and at set times after a risk | Tells you your status so you can act |
If you are unsure which fits, compare PEP vs PrEP side by side. After 72 hours, PEP is generally not recommended, but HIV testing in Pattaya and advice still matter.

Questions
HIV in Pattaya: quick answers.
Written by the HIV PEP Pattaya team, based on UNAIDS and AIDS Data Hub data. Last updated 29 September 2026.
What is the HIV rate in Pattaya?
No official source publishes a current HIV rate for Pattaya’s general population. National UNAIDS estimates put adult prevalence in Thailand at about 1%, and local surveys only cover specific groups.
What is the HIV infection rate in Thailand?
UNAIDS estimated about 9,100 new infections in 2023, around half the 2010 level. About 580,000 people were living with HIV that year.
Is Pattaya high risk for HIV?
The place matters far less than the encounter. Condomless sex with a partner of unknown status carries the same risk in Pattaya as anywhere else, and condoms, PrEP and PEP work just as well here.
Is HIV increasing in Thailand?
No. New infections and AIDS-related deaths have both fallen substantially since 2010, while treatment coverage has risen above 80%.
What should I do if I think I was exposed in Pattaya?
If it was within the last 72 hours, contact a clinic about PEP straight away. You can check the 72-hour PEP window and read how HIV PEP works, or see our HIV prevention services.
