Criminalization and Public Health Implications of HIV Transmission

Criminalization of HIV transmission, notably through laws that mandate disclosure or penalise non-disclosure, sits at the fraught intersection of legal policy and public health. Originally enacted to deter behaviours perceived as high risk and to protect uninfected individuals, many of these statutes rely on outdated conceptions of HIV epidemiology. Advances in antiretroviral therapy have transformed HIV into a chronic, manageable condition and, when viral suppression is achieved, reduced transmission risk to negligible levels. However, punitive legal frameworks often discourage individuals from seeking testing or disclosing their status, for fear of criminal penalties. This, in turn, perpetuates stigma, erodes trust in health services and impedes progress across the continuum of care—from early diagnosis and linkage to treatment to long-term adherence. The impact is disproportionately borne by marginalised groups, including women, migrants and key populations, exacerbating existing social inequities. Evidence suggests that aligning legal approaches with current scientific understanding, and adopting a rights-based framework, is essential to foster environments in which people living with HIV are empowered to access services, disclose status voluntarily and sustain engagement in effective prevention and treatment programmes.
