Participants will travel to Iquitos, Peru. The first two weeks will be spent in Iquitos at local hospitals and health care centers working with local physicians on inpatient and outpatient services. At least one day will be spent in the lab working with local technicians on diagnostic testing of tropical diseases. At least one day in Iquitos will be spent doing outreach clinics to the underserved population of the city. After completion of the first week the team will move to a remote location up the Amazon river to a tributary of the Yarapa river which will serve as our base. From there the team will visit 15-20 villages providing primary and urgent care to patients of all ages. Students will have an opportunity to work in our mobile lab and to work with portable ultrasonography. The team will be conducting multiple research projects and students will be able to participate in the development and implementation of those projects.
