The HAVANA Act of 2021: Congressional Recognition and Compensation for Anomalous Health Incidents

Legislative Origins: From Embassy to Capitol Hill

The path to the HAVANA Act began in 2016 when US Embassy personnel in Havana, Cuba began reporting a constellation of neurological symptoms following exposure to unexplained auditory and sensory phenomena. By 2017, the State Department had evacuated a significant portion of its Havana staff, and Congressional oversight committees had begun requesting classified briefings on the incidents. The Senate Select Committee on Intelligence and the House Permanent Select Committee on Intelligence both held closed hearings on AHI between 2018 and 2020, establishing the legislative groundwork for eventual statutory action.

The 2020 National Academies of Sciences report, which concluded that directed pulsed radio-frequency energy was the most plausible mechanism for the core AHI cases, provided the scientific foundation that legislators needed to justify a compensation framework. Prior to the NASEM report, the absence of a scientific consensus on mechanism had complicated efforts to establish eligibility criteria for compensation — a challenge that the report's findings substantially addressed, even while leaving attribution questions unresolved.

Key Provisions of the HAVANA Act

The Helping American Victims Afflicted by Neurological Attacks (HAVANA) Act of 2021 (Pub. L. No. 117-46) passed the Senate by unanimous consent on September 21, 2021, passed the House by voice vote on September 29, 2021, and was signed by President Biden on October 8, 2021. Its primary provisions authorized the Director of the CIA and the Secretary of State to pay compensation to covered individuals who suffered qualifying injuries from AHI.

Implementation Challenges and the Compensation Backlog

Despite the law's unanimous passage, implementation proved contentious. By mid-2022, numerous affected CIA officers reported that their compensation claims had been denied or delayed, prompting Congressional intervention. A July 2022 hearing before the Senate Intelligence Committee revealed that the CIA had approved only a small fraction of submitted claims, with agency officials citing evidentiary standards that critics argued were inconsistently applied.

The CIA's subsequent 2023 assessment — which concluded that most AHI cases were unlikely to have been caused by a foreign adversary — further complicated the compensation landscape. Some affected personnel and their advocates argued that the attribution assessment was being improperly conflated with the injury determination required under the HAVANA Act, which does not require attribution to a foreign actor as a condition of eligibility. The law requires only that the injury resulted from an AHI, not that the AHI be attributable to a specific source.

In response to these concerns, Congress passed the Anomalous Health Incidents Transparency Act in 2023, which required the CIA and State Department to provide more detailed reporting on claim determinations and to establish clearer eligibility criteria. The legislation also created an independent review board to hear appeals from individuals whose claims had been denied.

Extension to the Broader Intelligence Community

The original HAVANA Act covered only CIA and State Department personnel. Subsequent legislation and executive action extended compensation eligibility to personnel from the National Security Agency, Defense Intelligence Agency, National Geospatial-Intelligence Agency, and other components of the intelligence community. The Department of Defense also established its own AHI compensation framework for military personnel and their families, modeled on the HAVANA Act structure.

As of early 2026, the total number of AHI claims filed across all agencies exceeds 1,500, with compensation determinations varying significantly by agency. The State Department has historically had a higher approval rate than the CIA, a disparity that has been the subject of ongoing Congressional scrutiny.

Significance for the AHI Research and Policy Landscape

The HAVANA Act's significance extends beyond its immediate compensation function. Its passage represented the first formal Congressional acknowledgment that AHI constitutes a real category of injury warranting governmental response — a recognition that has shaped subsequent research funding, medical protocol development, and interagency coordination. The law's unanimous passage in a deeply divided Congress reflected the bipartisan nature of concern about the welfare of government personnel and the seriousness with which legislators viewed the underlying incidents.

The HSDI HELIOS architecture tracks the HAVANA Act and its implementing regulations as Tier 1 political and legislative milestones in the Incident Timeline module, and incorporates the compensation framework's eligibility criteria as contextual data points in the Differential Diagnosis Engine's environment context step. This integration reflects HSDI's commitment to treating the legal and policy record as an integral component of the evidentiary landscape, not merely a background context.
