Hypothesis
What is the source of the trichinellosis outbreak in northern Thailand?
Conclusion
Eating undercooked wild boar meat was strongly implicated as the source of this trichinellosis outbreak.
Supporting Evidence
- All 28 case-patients had myalgia and other symptoms.
- An environmental study linked the outbreak to eating wild boar meat.
- Laboratory tests confirmed the presence of Trichinella papuae in a muscle biopsy.
Takeaway
Some villagers got sick after eating wild boar meat that wasn't cooked enough, which made them very ill.
Methodology
The study involved reviewing medical records, interviewing patients, and conducting a case-control study with environmental investigations.
Potential Biases
Potential bias from self-reported symptoms and exposure history.
Limitations
The study was limited by the lack of available uncooked wild boar meat for laboratory analysis.
Participant Demographics
The study included 82 participants, with a median age of 34 years, and 18 were male.
