- (2)for acute rheumatic fever manifesting as isolated chorea or as indolent subclinical carditis only, having a group A beta-haemolytic streptococcal infection of the skin or the pharynx within the nine months before the clinical onset of acute rheumatic fever;
- (3)having a group C or G streptococcal infection of the pharynx within the three months before the clinical onset of acute rheumatic fever;
- (4)experiencing crowded living or working conditions within the one year before the clinical onset of acute rheumatic fever;
- (5)having dental caries within the one year before the clinical onset of acute rheumatic fever;
- (6)inability to obtain appropriate clinical management for acute rheumatic fever;
Aggravation-only factors: the factors in subsection 9(6) 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.

- (2)for acute rheumatic fever manifesting as isolated chorea or as indolent subclinical carditis only, having a group A beta-haemolytic streptococcal infection of the pharynx within the nine months before the clinical onset of acute rheumatic fever;
- (3)experiencing crowded living or working conditions within the one year before the clinical onset of acute rheumatic fever;
- (4)inability to obtain appropriate clinical management for acute rheumatic fever;
