The quarterly trend of laboratory reports for Campylobacter species (spp.) and non-typhoidal Salmonella spp. for the period Q1 2023 to Q2 2025 are shown in Table 1, this data includes infections acquired overseas.
The data is accurate as of 20 August 2025 and, as extracted from live surveillance systems, is reported as provisional and may be subject to change due to late notifications and de-duplication. Previously published totals may therefore differ slightly.
