Hypothesis
Does human cysticercosis cluster around tapeworm carriers?
Conclusion
Human cysticercosis seroprevalence is significantly higher near tapeworm carriers, but seizures do not cluster around them.
Supporting Evidence
- Seroprevalence was 24% among 803 individuals tested.
- Seroprevalence increased from 21% at >50 m from a carrier to 64% at the carriers' homes.
- Seizure prevalence was 3.0% among the participants.
Takeaway
People living close to tapeworm carriers are more likely to have cysticercosis, but having seizures doesn't seem to be related to living near these carriers.
Methodology
The study assessed seroprevalence of cysticercosis and seizure prevalence in relation to distance from tapeworm carriers in rural Peru.
Potential Biases
Potential exposure misclassification due to missed tapeworm carriers.
Limitations
The study did not use a sensitive test for detecting tapeworm carriers, which may have led to exposure misclassification.
Participant Demographics
Participants were from seven rural communities in Peru, with a total of 898 individuals analyzed.
