Hypothesis

Conclusion
The prevalence of A. cantonensis in wild rats and snails in Shenzhen poses a substantial risk for future outbreaks of human eosinophilic meningitis.
Supporting Evidence
- A. cantonensis larvae were found in 15.6% of examined snails.
- P. canaliculata had a significantly higher infection rate than A. fulica.
- A. cantonensis adults were recovered from 12% of examined rats.
- Infection rates were higher for female rats than for male rats.
Takeaway
In Shenzhen, snails and rats can carry a parasite that makes people sick, especially if they eat undercooked snails.

Survey of A. cantonensis in wild rats and snails using standardized procedures.
Participant Demographics
Population of Shenzhen is approximately 10 million, with a subtropical climate.
