Many countries around the world have laws that criminalise HIV transmission, non-disclosure or exposure. These laws vary enormously — from broad statutes that punish failing to disclose before sex, to narrower provisions that only apply to intentional transmission. The impact on people living with HIV can be significant, affecting disclosure decisions, access to testing and engagement with healthcare.
Here’s an overview of how different countries approach HIV criminalisation and what the UK law says.

Types of HIV Criminalisation
| Type | What It Means | Examples |
|---|---|---|
| Transmission | Punishes actually passing HIV to another person | UK (England & Wales), some US states |
| Exposure | Punishes putting someone at risk, even if no transmission occurs | Canada, many US states, some African countries |
| Non-disclosure | Punishes failing to tell a partner about HIV status before sex | Canada, some US states |
| HIV-specific statutes | Dedicated criminal offences for HIV | Many sub-Saharan African countries, some US states |
UK Law
England and Wales
There is no specific HIV offence. Prosecutions happen under general offences against the person (GBH). They require proof that transmission actually occurred and that the person who transmitted HIV did so recklessly — meaning they knew their status and took no steps to prevent transmission. Being on effective treatment (U=U), using condoms or the partner being on PrEP would all be relevant defences.
Scotland
Similar principles apply under Scots law, though the legal framework differs slightly.
Northern Ireland
Follows similar precedents to England and Wales.
UK prosecutions for HIV transmission are rare and require strong evidence of reckless behaviour.
International Picture
- Canada — has prosecuted non-disclosure even without transmission. Recent reforms have narrowed the law to require “realistic possibility of transmission”
- United States — laws vary hugely by state. Some still criminalise spitting or biting (which pose no HIV risk). Several states have modernised their laws
- Sub-Saharan Africa — many countries have HIV-specific criminal laws. Some criminalise exposure or non-disclosure broadly
- Australia — varies by state. Some have prosecuted under assault laws
Why Criminalisation Is Controversial
Public health experts and organisations including UNAIDS and the WHO argue that criminalisation:
- Discourages testing — you can’t be prosecuted for what you don’t know
- Increases stigma
- Disproportionately affects marginalised communities
- Often reflects outdated science (e.g. criminalising spitting, or ignoring U=U)
- Pushes people away from healthcare and disclosure
There is a growing global movement to reform these laws.

Frequently Asked Questions
Can I be prosecuted in the UK for having HIV?
Having HIV is not a crime. Prosecutions only arise if you recklessly transmit HIV to another person — and being on effective treatment, using condoms or the partner being on PrEP would all be relevant to your defence.
Does U=U protect me legally?
In practice, yes. If you are on effective treatment with an undetectable viral load, transmission is not possible and prosecution for reckless transmission would not succeed.
Should I travel to countries with HIV criminalisation laws?
Many countries with strict laws do not enforce them against travellers. However, it’s sensible to research local laws before travel, particularly if you carry HIV medication. Terrence Higgins Trust and NAM aidsmap have country-specific guidance.
