The quarterly trends of laboratory reports for Campylobacter species (spp.) and non-typhoidal Salmonella spp. (NTS) for the period Q1 2024 to Q2 2026 are shown in Table 1, this data includes infections acquired overseas.
The data is accurate as of 21 August 2026 and, as extracted from live surveillance systems, is reported as provisional and may be subject to change due to late notifications and de-duplication, therefore previously published totals may differ.
Key points
In the second quarter (Q2) of 2026 the numbers of confirmed Campylobacter spp. and NTS laboratory reports remained comparable to the same period in 2025.
The total number of confirmed Campylobacter spp. laboratory reports in 2025 was similar to the number in 2024, at 69,489 and 70,377 reports respectively (down 1.3%) (Table 1). Comparison of the number of confirmed Campylobacter spp. laboratory reports in the first quarter (Q1) of years 2024 and 2025 indicated a rise in the number of reports, from 12,985 reports in Q1 2024 to 16,031 in Q1 2025 (up 23.5%), then a decrease of 5.9% to 15,094 reports in Q1 2026. There was a slight decreasing trend in the number of confirmed Campylobacter spp. laboratory reports in Q2 of years 2024, 2025 and 2026, from 19,370 to 18,905 (down 2.4%) with a further decrease to 18,322 reports (down 3.1%).
The total number of confirmed NTS laboratory reports was comparable in 2024 and 2025, with 10,379 and 10,401 reports respectively (Table 1). Comparison of the number of confirmed NTS laboratory reports in Q1 of each year, 2024 to 2026, shows an increasing trend, from 1,541 reports in Q1 2024 to 2,021 reports in Q1 2026 (up 31.1%). There was a decrease of 1.6% in the number of confirmed NTS laboratory reports in Q2 2025 (n=2,348) when compared to the same period in 2024 (n=2,386), with an increase of 10.8% to 2,601 reports in Q2 2026.

Data sources
Data for this report was extracted on 21 August 2026 from the UKHSA live laboratory reporting database, the Second Generation Surveillance System (SGSS).
Data caveats
As data was extracted from SGSS, a live laboratory reporting system, the data is subject to change and historical totals may differ slightly.
Data cleaning
Regional classification in this report was based on ONS regional boundaries using patient residence postcode where available. Where patient residence or GP postcodes were not available, the referring laboratory postcode was used as a proxy. Previous reports used Nomenclature of Territorial Units for country and regional boundaries; therefore historical totals in previous publications may differ slightly. Updated regional totals were calculated for 2024 and 2025 for accurate comparison with 2026 data. These changes were made to ensure the same regional assignment methodology is used across all Campylobacter and NTS surveillance outputs.
