HIV criminalization means using HIV status to criminalize otherwise lawful conduct or increase penalties for an offense. Having HIV is not itself a crime. Many provisions require neither intent to transmit nor actual transmission; some reach conduct with no transmission risk. The requirements vary by jurisdiction and by statute.[2][5]
What these laws actually do
The Williams Institute uses the term for laws that change whether conduct is criminal, or how severely it is punished, because a person has HIV. Knowledge of status can be an element, but a diagnosis alone is not the prohibited conduct.[1]
CHLP’s September 15, 2026 maps distinguish 32 states with exposure/transmission offenses from 40 with any covered offense or enhancement. Categories overlap and include laws using broader disease terminology.[3][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 documented a mismatch between criminal penalties and the transmission evidence then available. That is a historical policy source, not the best source for today’s treatment-effectiveness estimates. Current CDC guidance supports U=U for sexual transmission; risks through other routes require separate assessment.[5]
Current CDC guidance states that maintaining viral suppression on treatment prevents sexual HIV transmission. That clinical finding does not establish a universal legal exemption. Both medical evidence and the requirements of a particular law matter.[6]
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 — disparities that provide context for examining unequal enforcement[2]. Between 2015 and 2025 the Williams Institute studied enforcement of HIV-related criminal laws in 16 states[2].
Sero Project centers the leadership of people living with HIV in organizing against criminalization and mass incarceration. Its work includes support networks and advocacy against unjust prosecutions. Communities affected by these laws should have a central role in deciding how reform is pursued.[8]
Federal guidance on reform
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’s archived HIV Criminalization Legal and Policy Assessment Tool (2022) helps jurisdictions compare laws with scientific evidence and examine privacy and equity. It recommends considering updates or repeal and notes that criminalization may discourage testing. This is published public-health guidance, not a statement that a state law has changed.[7]
How to find out what your own state does
CHLP’s Sourcebook offers statutory text, case law and legal analysis. Its chapters are updated at different times: check the relevant chapter’s date, then consult current official statutes and court decisions. CHLP’s maps provide an overview, while Williams Institute studies describe historical enforcement. These are starting points for research, not substitutes for qualified legal advice.[4][3][1]
Repeal of a particular HIV-specific offense does not necessarily remove other applicable criminal or health-code provisions. CHLP’s maps therefore include broader disease laws. Read reform announcements alongside the remaining law.[3]
Florida: all four categories at once
Florida’s CHLP profile identifies exposure/transmission and donation provisions, plus enhancements involving sex work and other listed offenses. These are distinct categories, with different statutory prerequisites.[9]
Florida §384.24(2) concerns sexual intercourse when the person knows their HIV status and has been informed about possible transmission. The partner must be informed and consent to intercourse. Section 384.34(5) specifies felony penalties. The intercourse provision contains no express viral-suppression exemption; this does not decide every possible evidentiary argument or defense. U=U remains the science of sexual transmission. Read the Florida guide.[10][6]
Fair treatment beyond an undetectable result
U=U is important evidence, but rights must not depend on a lab result. CHLP, SERO and partner organizations warn that reform limited to people who can document suppression leaves others behind. Unequal access to care is part of that concern.[12]
A lawyer may use relevant medical evidence in an individual defense. That is different from making suppression the condition for fair treatment in the law. Read about the viral divide and barriers to care, including housing, costs, mental health and substance use. These circumstances do not establish anyone’s viral load or intent.
Related questions
How many states criminalize HIV right now?
CHLP’s September 2026 maps identify 32 states with exposure/transmission offenses and 40 with at least one covered offense or enhancement. These are different, overlapping categories, including some broader disease laws. Check the dated map and current law.
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?
Maintained viral suppression prevents sexual HIV transmission. Its legal significance depends on the law and facts. Florida’s intercourse provision has no express viral-suppression exemption. Consult a qualified lawyer rather than assuming U=U automatically prevents prosecution.
Has the federal government said anything about these laws?
Yes. DOJ published reform guidance in 2014, and CDC published a legal and policy assessment tool in 2022. These historical guidance documents support evaluating laws against scientific evidence and equity; they do not themselves repeal state statutes.
