Four-week reporting period (26 September – 23 October 2022)
As of report 62 onward, the case data provided in this report includes both confirmed and probable cases reported to the National Notifiable Diseases Surveillance System (NNDSS), unless otherwise specified. Case definitions for confirmed and probable cases are in accordance with the coronavirus disease 2019 (COVID-19) Series of National Guidelines for Public Health Units (SoNG).
At the time of extraction, probable cases were incomplete from Victoria since 29 July 2022. On 24 October 2022, Queensland commenced the transmission of all rapid antigen test (RAT) positive cases to NNDSS, which will be completed over the coming weeks; prior to 24 October 2022, Queensland only reported probable cases that had a RAT conducted in a clinical setting; probable cases who tested via RAT outside of a clinical setting were not reported to NNDSS. Therefore, interpretation of historical trends in Queensland should be undertaken with caution until the transmission of all RAT cases is complete.
Trends – Nationally, weekly case numbers have remained relatively stable since late September 2022. In the reporting period 26 September – 23 October 2022, there were 40,009 confirmed and 88,214 probable cases of COVID-19 reported in Australia to NNDSS. In the latter fortnight (10–23 October 2022) of the reporting period, 60,333 confirmed and probable cases were notified (an average of 4,310 cases per day), compared to 67,890 in the previous fortnight (4,849 cases per day); together, these mark the lowest case numbers observed in a reporting period during 2022.
