On 13/03/2026 survivors, advocates and legal teams continued to challenge a category of statutes often called exposure laws, laws that in many states still criminalize nondisclosure of an HIV diagnosis. These statutes frequently force people living with HIV into the machinery of the criminal justice system: testing, arrest or mandatory placement on a sex-offender registry. For those affected, the choice can be described bluntly as “take the test, risk arrest.” The debate around these laws centers on the tension between historical public fear and contemporary medical knowledge.
The people most often targeted are not a random cross-section of the population. Attorneys, public-health experts and civil-rights groups note a pattern: enforcement usually lands on the shoulders of LGBTQIA+ Americans of color and those with the least access to legal resources. Activists describe the statutes as relics from the early days of the epidemic, preserved in criminal codes despite advances in treatment and prevention. Campaigns now seek to reconcile criminal law with the science of antiretroviral therapy and the undetectable equals untransmittable (U=U) principle.
Origins and persistence of exposure laws
Many of the statutes in question were written decades ago when HIV carried a far different prognosis and public understanding. At that time, lawmakers framed criminal penalties around fear of transmission and a desire to deter nondisclosure. The language often criminalizes the act of exposure itself, which advocates label as an outdated legal concept that fails to reflect modern epidemiology. Despite newer scientific consensus, legislatures have been slow to revise or repeal these provisions, leaving a patchwork of rules across states that continue to govern behavior in ways that medical experts say are ineffective and counterproductive.
Because these laws remain on the books, prosecutors retain wide discretion. That discretion can magnify existing biases within policing and judicial systems. Where statutes are vague about what constitutes harmful conduct, enforcement becomes uneven: similar conduct that might be treated as a public-health matter in one jurisdiction is prosecuted as a felony in another. Legal scholars argue that this inconsistency undermines both public health goals and the fair application of criminal law.
Science, stigma and the law
Modern treatment has transformed HIV from a likely fatal illness into a manageable chronic condition for many people. Antiretroviral therapy can suppress viral load to the point that transmission is effectively eliminated, a concept summarized by the U=U message. Yet many statutes do not account for viral suppression, condom use, or other risk-reduction measures. That legal mismatch means that individuals who pose negligible or zero transmission risk under contemporary science may still face criminal penalties. Public-health professionals warn that criminalization can discourage people from getting tested and seeking care, counteracting prevention efforts.
Disparate enforcement and communities harmed
Data and case studies show that enforcement disproportionately burdens LGBTQIA+ Americans of color, people with unstable housing and those involved in sex work. These groups often encounter law enforcement more frequently, and when charged, they face the severe collateral consequences of being listed on a sex-offender registry: restricted housing, loss of employment opportunities and social ostracism. Civil-rights organizations argue that when public policy intersects with poverty, racism and homophobia, criminal statutes become tools of marginalization rather than instruments of public safety.
Legal battles and paths to reform
Litigation, legislative repeal campaigns and public-education efforts are the main strategies advocates are using to challenge the status quo. Some lawsuits assert that enforcement violates constitutional protections; others push for statutory amendments that align legal language with scientific evidence, including explicit references to viral suppression and intent to transmit. Lawmakers in several states have introduced bills to narrow or eliminate exposure-related offenses, while public-health groups promote alternatives that prioritize treatment and prevention. Advocates emphasize that law reform coupled with robust access to healthcare offers a more just and effective response than criminalization.
