Terminology used in Tables/Figures

Age-specific rate Notification rate for a specified age group. Both numerator and denominator refer to the same age group. Expressed per 100,000 persons in that age group

Age-standardised rate (ASR) Notification rate adjusted to take account of differences in age composition when rates for different populations are compared. Expressed per 100,000 population

Crude rate Calculated by dividing the number of notifications by the population. Not adjusted for age or other factors. Expressed per 100,000 population

Infectious syphilis Primary syphilis + secondary syphilis + early latent (less than two years duration)

N/A Not applicable

Non-infectious syphilis Syphilis infection of more than two years or unknown duration

Notification rate See crude rate and age-standardised rate

Number Number of notifications reported to the DoH/state and territory health authorities

Rate ratio (Aboriginal:non-Aboriginal) Aboriginal to non-Aboriginal rate ratio = ASR (Aboriginal)/ASR (non-Aboriginal)

Rate ratio (Male:Female) Male to female rate ratio = ASR (male) / ASR (female)

Total hepatitis B notifications Newly acquired hepatitis B + unspecified hepatitis B

Total hepatitis C notifications Newly acquired hepatitis C + unspecified hepatitis C

Total syphilis notifications Infectious syphilis + non-infectious syphilis

The follow-up and allocation of cases to newly acquired hepatitis C is highly dependent on public health follow-up which is variable between jurisdictions. Trends between newly acquired and unspecified hepatitis C cases within jurisdictions and over time therefore need to be interpreted cautiously.
