Hypothesis
Is there an unrecognized reservoir for malaria in Espírito Santo, Brazil?
Conclusion
The study suggests the possibility of a simian reservoir for malaria due to low incidence and asymptomatic cases.
Supporting Evidence
- 95% of patients were experiencing their first episode of malaria.
- Asymptomatic residents showed positive results for malaria antibodies.
- The majority of patients had low parasite counts.

Methodology
The study surveyed 65 patients and 1,777 residents using blood tests and questionnaires over three years.
Potential Biases

Limitations
The study may have information bias regarding travel and forest visits.
