Understanding the Legal Landscape Around HIV
In Singapore, HIV is treated not just as a medical condition but also as a public health matter with legal implications. For years, people diagnosed with HIV have faced specific obligations under the Infectious Diseases Act. These include disclosure requirements to sexual partners and, in some cases, potential criminal penalties for non-disclosure.
These laws were introduced to protect public safety, but critics have long debated whether they also contribute to stigma and discourage people from getting tested. At the same time, major advancements in HIV treatment have changed the way the virus behaves and how it is managed. Today, people living with HIV who adhere to their medication can become undetectable and untransmittable through sex.
In 2024, Singapore introduced an important legal update that reflects this medical reality. This article breaks down what the law says, what has changed, and what it means for individuals living with HIV or concerned about their legal responsibilities.

What Changed in 2024 and Why It Matters
In 2024, Singapore amended Section 23 of the Infectious Diseases Act to exempt certain individuals living with HIV from the legal requirement to disclose their status to sexual partners. This change only applies if they meet a strict set of medical conditions.
The revised law acknowledges the principle of Undetectable = Untransmittable (U=U). This means that someone whose viral load is suppressed through medication cannot pass the virus on through sexual contact.
To qualify for this legal exemption, the person must:
- Have been on HIV treatment continuously for at least six months
- Have a viral load test result from the last nine months confirming undetectable status
- Have obtained test results from a recognised laboratory
- Have adhered to their medication and have no reason to believe their viral load has changed
This change marks a shift in Singapore’s HIV policy, from risk-focused to science-informed. It also affirms that people who are on treatment and undetectable should not be punished for posing no risk to others.

What Hasn’t Changed in Singapore’s HIV Law
While the 2024 amendment provides legal protection for people with an undetectable viral load, it does not remove disclosure requirements for everyone. Individuals who do not meet the criteria for exemption are still legally required to inform their sexual partners about their HIV status before engaging in sexual activity.
This means disclosure is still mandatory if:
- You are newly diagnosed and have not completed six months of consistent treatment
- Your most recent viral load test is outdated or not undetectable
- You are unsure whether your viral load remains suppressed
- You have not been following your medication regimen
In these situations, failing to disclose can result in serious penalties under the Infectious Diseases Act, including imprisonment of up to 10 years or fines of up to $50,000.
Is Condom Use Enough to Avoid Disclosure?
Some may assume that using condoms provides a legal safeguard, but under Singapore law, condom use alone does not exempt someone from the duty to disclose their HIV-positive status. The law focuses on the risk of transmission, and unless your viral load is undetectable and meets the criteria mentioned earlier, disclosure remains legally required.
This can be confusing for individuals who practice safer sex consistently. It also highlights the importance of staying on treatment and getting regular HIV testing to document your viral load status through proper channels.
If you believe you may have been exposed to HIV, you should seek HIV PEP within 72 hours of exposure. For more details, refer to our guide “HIV PEP Frequently Asked Questions”.
Why Singapore Updated Its HIV Law
The decision to revise the law reflects years of global medical research and advocacy. Evidence shows that people on antiretroviral treatment who achieve viral suppression do not transmit HIV sexually. This has been validated through multiple large-scale studies and is now a foundational principle in HIV care.
By aligning the law with current science, Singapore sends a clear message: HIV is a manageable condition, not a public threat. This legal shift also supports the country’s broader goal of meeting the UNAIDS 95-95-95 targets — which aim for 95 percent of people living with HIV to know their status, 95 percent of those to be on treatment, and 95 percent of those treated to achieve viral suppression.
Updating the law is not just about legal language. It is about improving health outcomes, reducing fear, and encouraging people to get tested and treated earlier.
Reducing HIV Stigma Through Policy
For many years, criminalisation and mandatory disclosure laws have been a source of fear for people living with HIV. Even those committed to treatment felt uncertain about what might happen if they slipped up or missed an appointment. Some avoided getting tested altogether out of fear of the legal consequences.
By acknowledging that people with an undetectable viral load are not a transmission risk, the law helps reduce stigma and promote trust in the healthcare system. It also empowers people with HIV to live openly and responsibly, without being treated as a legal liability.

What Health Advocates Are Saying
Singapore’s HIV advocacy groups, including Action for AIDS (AfA), have welcomed the change. They note that the amendment brings the law closer to modern medical understanding and will likely boost early testing and treatment uptake. It is also seen as a step toward more humane, rights-based healthcare policies.
However, some experts caution that public education must keep pace. There is still confusion around what it means to be undetectable and who is legally protected. Clearer outreach to healthcare providers and the general public will be key to ensuring that the law does not leave anyone behind.
Self-Testing: A Game Changer on the Horizon
Singapore is also planning to introduce HIV self-test kits at pharmacies nationwide. These kits will allow individuals to check their status in private, without needing to visit a clinic. This complements legal reform by making it easier for people to take charge of their health without fear or stigma.
Self-testing is expected to increase uptake, especially among younger individuals and those who feel nervous about traditional testing environments. When combined with access to PrEP, PEP, and judgment-free care, self-testing could play a major role in Singapore’s long-term HIV prevention strategy.
What This Means for You
If you are living with HIV in Singapore, the recent legal changes mean that the law now recognises what your treatment is already doing — keeping you healthy and protecting others. Staying on antiretroviral therapy, going for regular viral load tests, and working with your healthcare provider ensures that you meet the legal exemption criteria while also protecting your long-term health.
If you are at risk of HIV or simply want peace of mind, routine testing and early access to PrEP or PEP can help you stay protected. You do not have to wait for symptoms or a scare to get tested. At Shim Clinic, confidential and non-judgmental testing is always available.
For partners, family members, and friends of people living with HIV, understanding the science behind U=U helps build trust and reduce stigma. When we treat HIV as a manageable medical condition rather than a moral issue, we create space for healthier conversations, better relationships, and safer communities.
A Law That Listens to Science
Singapore’s amendment to its HIV law is a significant step toward integrating science, policy, and compassion. By recognising that people with undetectable viral loads do not pose a transmission risk, the law now supports public health goals without unnecessarily punishing individuals who are managing their condition responsibly.
There is still more to be done – from education to legal protections against discrimination — but this change lays the groundwork for a better future. One where getting tested is encouraged, treatment is supported, and people living with HIV are treated with dignity, not fear.
