Meaning of human t-cell lymphotropic virus type-1 infection: For the purposes of this Statement of Principles, human T-cell lymphotropic virus type-1 infection means an infection that is caused by the retrovirus human T-cell lymphotropic virus type-1 (HTLV-1). (3) While human T-cell lymphotropic virus type-1 infection attracts ICD-10-AM code Z22.6, in applying this Statement of Principles the meaning of human T-cell lymphotropic virus type-1 infection is that given in subsection (2).

Reasonable Hypothesis (RH) — Statement of Principles No. 96 of 2018
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting human T-cell lymphotropic virus type-1 infection or death from human T-cell lymphotropic virus type-1 infection with the circumstances of a person's relevant service:
- (1)being exposed to HTLV-1 before the clinical onset of human T-cell lymphotropic virus type-1 infection;
Note: being exposed to HTLV-1 is defined in the Schedule 1 - Dictionary.
- (2)having: (a) herpes simplex virus type 2 anogenital infection; or (b) a genital ulcerative disease; or (c) a non-ulcerative anogenital sexually transmitted infection with clinical symptoms or signs, excluding genital warts; within the four weeks before the clinical onset of human T-cell lymphotropic virus type-1 infection;
- (3)having infection with human immunodeficiency virus at the time of the clinical worsening of human T-cell lymphotropic virus type-1 infection;
- (4)inability to obtain appropriate clinical management for human T-cell lymphotropic virus type-1 infection;
Aggravation-only factors: the factors in subsections 9(3) and 9(4) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
Balance of Probabilities (BoP) — Statement of Principles No. 97 of 2018
2 factors
At least one of the following factors must exist before it can be said that, on the balance of probabilities, human T-cell lymphotropic virus type-1 infection or death from human T-cell lymphotropic virus type-1 infection is connected with the circumstances of a person's relevant service:
- (1)being exposed to HTLV-1 before the clinical onset of human T-cell lymphotropic virus type-1 infection;
Note: being exposed to HTLV-1 is defined in the Schedule 1 - Dictionary.
- (2)inability to obtain appropriate clinical management for human T-cell lymphotropic virus type-1 infection;
Aggravation-only factors: the factors in subsection 9(2) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
