Variation in incidence and notification of Campylobacter and Salmonella by general practice in the Thames Valley area

Substantial variation in the diagnosed incidence and notification of Salmonella and Campylobacter by general practice in the Thames Valley area exists. Practice-level factors are likely to account for some of the difference in testing and under-notification. This is important for interpreting data from surveillance systems. Further research is needed to inform interventions designed to increase notifications or improve testing.
