HIV and STD Criminalization Laws

As of 2020, 37 states have laws that criminalize HIV exposure.
The laws for the 50 states and the District of Columbia were assessed and categorized into four categories.

  1. HIV-specific laws that criminalize or control behaviors that can potentially expose another person to HIV.
  2. Sexually transmitted disease (STD), communicable, contagious, infectious disease (STD/communicable/infectious disease) laws that criminalize or control behaviors that can potentially expose another person to STDs/communicable/infectious disease. This might include HIV.
  3. Sentence enhancement laws specific to HIV, or STD that do not criminalize a behavior but increase the sentence length when a person with HIV commits certain crimes.
  4. No specific criminalization laws.

General criminal statutes, such as reckless endangerment and attempted murder, can be used to criminalize behaviors that can potentially expose another to HIV and or an STD. Many states have laws that fall into more than one of the categories listed above. For this analysis, only HIV-specific laws are captured for states with both HIV-specific laws and STD/communicable/infectious disease laws. Only HIV or STD/communicable/infectious disease laws are captured for states with both HIV or STD/communicable/infectious disease laws and sentence enhancement statutes.

During the early years of the HIV epidemic, many states implemented HIV-specific criminal exposure laws to discourage behavior that might lead to transmission, promote safer sex practices, and, in some cases, receive funds to support HIV prevention activities. These laws were passed at a time when very little was known about HIV including how HIV was transmitted and how best to treat the virus.  Many of these state laws criminalize behaviors that cannot transmit HIV – such as biting or spitting – and apply regardless of actual transmission, or intent. After over 30 years of HIV research and significant biomedical advancements to treat and prevent HIV transmission, many state laws are now outdated and do not reflect our current understanding of HIV. In many cases, this same standard is not applied to other treatable diseases. Further, these laws have been shown to discourage HIV testing, increase stigma, and exacerbate disparities.

Criminalization of potential HIV exposure is largely a matter of state law, with some Federal legislation addressing criminalization in discrete areas, such as blood donation and prostitution. These laws vary as to what behaviors are criminalized or what behaviors result in additional penalties. Several states criminalize one or more behaviors that pose a low or negligible risk for HIV transmission.

In 21 states, laws require people with HIV who are aware of their status to disclose their status to sex partners, and 12 states require disclosure to needle-sharing partners.

The maximum sentence length for violating an HIV-specific statute is also a matter of state law. Some states have a maximum sentence length up to life in prison, while others have maximum sentence lengths that are less than 10 years. However, only 9 states have laws that account for HIV prevention measures that reduce transmission risk, such as condom use, and antiretroviral therapy (ART).

Since 2014, at least five states have modernized their HIV criminal laws. Changes include removing HIV prevention issues from the criminal code and including them under disease control regulations, requiring intent to transmit, actual HIV transmission, or providing defenses for taking measures to prevent transmission such as viral suppression or being noninfectious, condom use, and partner PrEP use.
