COVID-19 cases by age group and sex
This graph shows the number of COVID-19 cases for males and females by age group since the first case was reported.
This bar chart shows the number of COVID-19 cases for males and females by age group since the first confirmed cases were reported in late January 2020.
The horizontal axis shows the age breakdown in 10-year intervals from zero years old to greater than 90 years old.
The vertical axis shows the number of COVID-19 cases.
As per the COVID-19 national guidelines, a COVID-19 confirmed case is a person who:
- tests positive to a validated specific SARS-CoV-2 nucleic acid test or
- has the virus isolated in cell culture, with PCR confirmation using a validated method or
- undergoes a seroconversion to or has a significant rise in SARS-CoV-2 neutralising or IgG antibody level (e.g. four-fold or greater rise in titre).
The proportion of COVID-19 cases in males and females is roughly equal, however the ratio does differ across the age groups presented.
Cases have been reported across all age groups. The majority of all cases are reported in those aged 20 to 59 years. The number of cases is highest in the 20–29 years age group.
