Main Article

Figure

Age-specific pertussis notification rates per 100,000 population for persons 0–20 years of age, by year notified, New South Wales, Australia, 2015 and 2024. Because no population data were available for children 0–5 months and 6–11 months, the total population estimates for children <1 year of age in 2015 and 2024 was halved. These populations were used for the rate calculations.
