Background  Neurocysticercosis is a leading cause of seizures and epilepsy in most of the world, and it occurs when  Taenia solium  larval cysts infect the central nervous system.  T. solium  tapeworm infection is endemic in much of Peru, but there are scarce data on the prevalence in many rural highland communities where it is likely to be hyper-endemic. Peace Corps Volunteers live and work in these communities; however, to our knowledge, they have not been used to facilitate public health research.    Materials and Methods  We utilized Peace Corps Volunteers to estimate the prevalence of  T. solium  tapeworm infection in seven rural communities in northern Peru. A convenience non-random sampling frame was used. Peace Corps Volunteers facilitated the collection of stool samples (N = 2,328), which were analyzed by sedimentation and microscopy. Niclosamide treatment and purgation preceded species identification, which was done by PCR-REA.    Results    Taenia  sp. egg-positive stool samples were found in three of the seven communities we surveyed. The overall prevalence of  Taenia  sp. egg positivity was 2.1% (49/2,328) (95% CI = 1.6–2.8%) with prevalence up to 4.3% (42/977) (95% CI = 3.1–5.8%) by community. All 34 of the specimens tested by PCR-REA were  T. solium . The overall prevalence of  T. solium  tapeworm infection was 1.5% (34/2,328) (95% CI = 1.0–2.0%). Prevalence up to 2.9% (28/977) (95% CI = 1.9–4.1%) by community was observed.    Conclusion/Significance  This study recorded high  T. solium  tapeworm prevalence, and identified hyper-endemic rural communities. It demonstrates that synergy between researchers and Peace Corps Volunteers can be an effective means to conducting large-scale, community-based studies in remote areas of Peru.
