HIV Disclosure and the Law in South Africa: What the 2026 Proposals Mean

← Haven News

South Africa is one of the few countries with a high HIV burden that does not have specific HIV disclosure legislation. Instead, disclosure issues are handled under common law — general legal principles that apply to any harmful act.

In 2026, the Law Commission and the SA Council of Churches have proposed changes that would criminalize non-disclosure of HIV status to sexual partners. The proposals are not yet law, but they are being actively debated.

What the current law says

South Africa has no law that specifically requires HIV disclosure. However, common law principles can apply:

• Attempted murder — if someone knows they are HIV-positive, knows they are not on treatment, and has unprotected sex with the specific intent to infect their partner
• Assault — if someone transmits HIV through negligence
• Failure to disclose — has been prosecuted in a small number of cases, with mixed outcomes

In practice, prosecutions have been rare. The law is applied inconsistently, and there is no clear legal standard for what "disclosure" requires.

What the proposed changes would do

The Law Commission has proposed legislation that would:

• Create a specific legal duty to disclose HIV-positive status before sexual contact
• Criminalize non-disclosure, with penalties potentially rising to the level of rape under the Criminal Law (Sexual Offences and Related Matters) Amendment Act
• Provide a defence if the person living with HIV is virally suppressed (undetectable)

Why this is controversial

Arguments for criminalization

• It protects people from being exposed to HIV without their knowledge
• It creates a clear legal standard that currently does not exist
• It recognises the harm of non-disclosure as a form of assault

Arguments against criminalization

• It discourages testing. If testing means you now have a legal duty to disclose, some people will avoid testing entirely.
• It increases stigma. Criminalization reinforces the idea that HIV-positive people are dangerous.
• It is applied unevenly. In countries with HIV criminalization laws, prosecutions disproportionately target women, migrants, and men who have sex with men.
• It ignores U=U. If someone is undetectable, they cannot transmit HIV. The proposed defence recognises this, but not all legal systems do.
• It assumes disclosure is always safe. Disclosing to a partner carries real risks — violence, abandonment, loss of housing or employment. The law would force people to choose between legal risk and physical risk.

What UNAIDS says

UNAIDS has consistently opposed the criminalization of HIV non-disclosure. Its 2023 guidance states that criminalization "creates a disincentive to testing and disclosure, and undermines public health efforts to end the AIDS epidemic."

UNAIDS supports legal frameworks that protect people from intentional transmission but recommends these be narrow and evidence-based, with clear defences for undetectable status.

What this means for you

Right now, nothing changes. The proposals are not law. The current legal position — that non-disclosure may be prosecuted under common law, but rarely is — remains in place.

Three practical points:

• Keep taking your treatment. If you are undetectable, you cannot transmit HIV. That is the strongest legal and ethical defence you can have.
• Consider disclosure timing. There is no legal requirement to disclose on a first date. But before sex, in most cases, disclosure is both ethically appropriate and legally safer.
• Stay informed. If the proposed legislation becomes law, the details will matter enormously. What counts as disclosure? What is the standard of proof? What defences are available? These will be clarified if and when a bill is passed.
