Hypothesis
To estimate multipliers linking surveillance of salmonellosis, campylobacteriosis, and Shiga toxin–producing Escherichia coli (STEC) infections to community incidence.
Conclusion
The study estimated that a significant number of cases of salmonellosis, campylobacteriosis, and STEC infections go unreported in Australia.
Supporting Evidence
- Estimated multipliers for salmonellosis, campylobacteriosis, and STEC were found to be 7, 10, and 8 respectively.
- Annual community incidence rates were estimated as 262 for salmonellosis, 1,184 for campylobacteriosis, and 23 for STEC per 100,000 population.
- High prevalence of these diseases was indicated by the multipliers derived from the study.
Takeaway
This study found that many people with foodborne illnesses don't get counted in official reports, so the real number of sick people is much higher than what we see.
Methodology
The study used data from a gastroenteritis survey and other sources to estimate multipliers for severe and milder cases of infections.
Potential Biases
Potential biases may arise from the reliance on self-reported data and the accuracy of laboratory testing.
Limitations
The study relies on existing data and may not capture all cases due to underreporting.
Participant Demographics
The study included a random stratified sample from all states in Australia.
