HIV criminalization laws are criminal statutes that punish people for knowing they have HIV — either by making otherwise-legal conduct a crime, or by stacking harsher penalties onto an existing offense. Thirty-two states still had such laws at the end of 2025[2]. Most require no intent to transmit, no actual transmission, and no conduct capable of transmitting HIV at all[5].
What these laws actually do
The Williams Institute at UCLA School of Law defines HIV criminalization as a term for “laws that either criminalize otherwise legal conduct or increase the penalties for illegal conduct based on a person's HIV-positive status,” and notes that more than two-thirds of U.S. states and territories have enacted them[1]. That is the whole architecture in one sentence: the thing being punished is knowledge of a diagnosis.
The Center for HIV Law and Policy (CHLP) counts 32 states that criminalize people living with HIV and 28 states with penalty enhancements that elevate charges based on a person's knowledge of their HIV status[3]. CHLP's map set, released in February 2025 and updated November 12, 2025, grades laws on an “HIV specificity scale” because many statutes reach people living with HIV through indirect “communicable disease” language rather than by naming HIV; the November update added a Donation Offenses map, showing donation offenses at the federal level and in 14 states[3].
The U.S. Department of Justice's own summary of the category describes laws reaching non-disclosure of known HIV status while sharing needles, while engaging in sex work “regardless of risk of the act,” or during the commission of a sex crime; laws reaching “behavior such as biting, spitting, and the throwing of bodily fluids”; and laws reaching non-disclosure before “adult consensual sexual behaviors of various types.” In some states the consequences include sex offender registration and involuntary civil commitment after incarceration[5].
No intent, no transmission, sometimes no risk at all
This is the part that surprises people most. The Williams Institute states plainly that “most HIV-related criminal laws do not require actual HIV transmission or intent to transmit HIV,” and that “some laws criminalize conduct that cannot transmit HIV and ignore mitigation and prevention strategies”[2].
DOJ's 2014 guidance put numbers to the mismatch: antiretroviral treatment reduces transmission risk by up to 96%, consistent condom use by about 80%, and the two together by 99.2% — while CDC classifies biting, spitting, and throwing body fluids as negligible risk. DOJ also cited a March 2014 DOJ/CDC analysis in AIDS and Behavior finding that most of these state laws criminalize behaviors CDC regards as posing “either no or negligible risk for HIV transmission”[5].
The science has moved further since. HIV.gov states that a person who takes HIV medicine as prescribed, reaches and keeps an undetectable viral load, and stays in care will not transmit HIV to sexual partners — vaginal, anal, or oral — and that large studies of thousands of couples recorded no transmissions from a partner who was virally suppressed[6]. Most of these statutes were written before any of that was known, and were never rewritten.
Who these laws actually land on
Criminalization does not fall evenly. In February 2026 the Williams Institute reported that Black Americans were about 12% of the U.S. population but 39% of people living with HIV and 38% of new diagnoses in 2023, while prison incarceration rates for Black Americans run nearly five times those for white Americans — two disparities that multiply where HIV-specific criminal laws exist[2]. Between 2015 and 2025 the Williams Institute studied enforcement of HIV-related criminal laws in 16 states[2].
The Sero Project, the national organization built by and for people living with HIV on this issue, describes its work as centering “PLHIV leadership to end HIV criminalization, mass incarceration, racial and social injustice,” and is “focused on ending inappropriate criminal prosecutions” of people living with HIV for non-disclosure, potential or perceived exposure, and transmission[8]. That framing matters: these are not neutral public-health tools that happen to have side effects. They are a mechanism of punishment aimed at a diagnosis.
Where the federal government stands
In July 2014 the DOJ Civil Rights Division published its Best Practices Guide to Reform HIV-Specific Criminal Laws to Align with Scientifically-Supported Factors, which states that “the best practice would be for states to reform these laws to eliminate HIV-specific criminal penalties” — with only two narrow exceptions: where a person who knows they have HIV commits a non-HIV-specific sex crime carrying transmission risk, and where the evidence clearly shows intent to transmit plus conduct posing significant risk[5]. CHLP maintains the record for that guidance in its resource library[11]. The guide counted 33 states with HIV-specific criminal laws at the time — a reminder to always date the count you are quoting[5].
CDC leaders have been blunter still. Writing on HIV.gov, the directors of CDC's Division of HIV Prevention and of NCHHSTP wrote that “all state laws and practices should be informed by science, and in the case of HIV criminalization laws, most are not,” and that “the implementation of HIV criminalization laws was not associated with reduced HIV incidence.” CDC released an HIV Criminalization Legal and Policy Assessment Tool in 2022, and the National HIV/AIDS Strategy encourages states to reform these laws[7].
How to find out what your own state does
Two tools do this properly, and both are free. CHLP's HIV Criminalization in the United States: A Sourcebook on State and Federal HIV Criminal Law and Practice — third edition, updated January 2024 — covers all 50 states plus the military, federal prisons, and U.S. territories, with statutory text, case law, sentence enhancements, and registration requirements[4]. CHLP's map set is the faster visual answer[3], and the Williams Institute publishes state-level enforcement briefs that show how a law is actually used, not just how it reads[1].
One caution worth carrying: repeal of an HIV-specific statute does not always remove a state from the map. After North Dakota and Maryland fully repealed their HIV-specific exposure offenses in 2025, CHLP reported that “the overall count of states with HIV-specific exposure and transmission laws remains the same at 32,” because both states kept health-code offenses that still reach people living with HIV through “communicable disease” and “infectious disease” language[3].
Florida: all four categories at once
Florida is one of the 32 states. CHLP's Florida profile records that Florida holds all four categories CHLP tracks simultaneously: an HIV-specific exposure and transmission offense, an HIV-specific donation offense, a sex work penalty enhancement, and a general criminal law penalty enhancement[9].
Florida's central provision, Fla. Stat. § 384.24(2), is a third-degree felony and requires neither intent to transmit nor actual transmission, and the Williams Institute notes Florida's laws were never updated to account for barrier protection or an undetectable viral load[10]. Put that next to HIV.gov's statement that sustained viral suppression means HIV is not transmitted sexually[6] and the gap is the story. This page is general information, not legal advice.
Related questions
How many states criminalize HIV right now?
Thirty-two states, as of the end of 2025, according to the Williams Institute and CHLP, and 28 states have penalty enhancements tied to knowing your HIV status. Counts drift as states reform their laws, so always check the date on any number you see — DOJ counted 33 states back in 2014.
Do these laws require that HIV was actually transmitted?
Usually not. The Williams Institute reports that most HIV-related criminal laws require neither actual transmission nor intent to transmit, and some reach conduct that cannot transmit HIV at all. A handful of reformed states now require intent plus real risk plus actual transmission, but they are the exception.
Does an undetectable viral load protect me legally?
Scientifically it is decisive; legally it depends entirely on your state. Only a small number of states have written treatment and viral suppression into their statutes, and most have not. CHLP's Sourcebook is the place to check your own state's text, and a lawyer licensed where you live is the place to get an answer about your situation.
Has the federal government said anything about these laws?
Yes. DOJ's Civil Rights Division called on states in 2014 to eliminate HIV-specific criminal penalties except in two narrow circumstances, and CDC leaders wrote on HIV.gov that most HIV criminalization laws are not informed by science and were not associated with reduced HIV incidence. CDC also published an assessment tool in 2022 to help states review their own laws.
