Reasonable Hypothesis (RH) — Statement of Principles No. 9 of 2017
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 ascariasis or death from ascariasis with the circumstances of a person's relevant service:
- (1)being exposed to Ascaris lumbricoides or Ascaris suum within the two years before the clinical onset of ascariasis;
Note: being exposed to Ascaris lumbricoides or Ascaris suum is defined in the Schedule 1 - Dictionary.
- (2)being in a tropical or subtropical region, where facilities for disposal of human waste are minimal and there is a high likelihood of the environment being contaminated with human faeces, within the two years before the clinical onset of ascariasis;
- (3)living or working in warm and damp conditions, in the presence of material contaminated with human faeces such as may occur in mines or tunnels, within the two years before the clinical onset of ascariasis;
- (4)inability to obtain appropriate clinical management for ascariasis;
Aggravation-only factors: the factors in subsection 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.

Note: being exposed to Ascaris lumbricoides or Ascaris suum is defined in the Schedule 1 - Dictionary.

- (3)living or working in warm and damp conditions, in the presence of material contaminated with human faeces such as may occur in mines or tunnels, within the two years before the clinical onset of ascariasis;
- (4)inability to obtain appropriate clinical management for ascariasis;
