Syllabus


WEEK 1


Welcome and Course Overview



Welcome to Tropical Parasitology: Protozoans, Worms, Vectors, and Human Diseases! In this course, students will develop an understanding of important human parasitic diseases, including their life cycles, vectors of transmission, distribution and epidemiology, pathophysiology and clinical manifestations, treatment, and prevention and control. Tropical Parasitology is taught by Kilimanjaro Christian Medical University College faculty -- Drs. Frank Mosha and Mramba Nyindo (and two lecturers, Drs. Johnson Matowo and Jovin Kitau). They are joined by Dr. John Bartlett, Professor of Medicine, Global Health and Nursing at Duke University. To get started, view the video "Welcome to Tropical Parasitology," read the Course Overview, read about how the course is structured in Course Clusters, and review the Course Resources. Then move on to study the first cluster, Protozoans. Please note that the Protozoans cluster constitutes the largest content cluster in the course, and we have allocated 3 weeks to complete the work for this cluster. The other course clusters will take one week (each) to complete. We hope you enjoy the course, and we look forward to your contributions to our learning community.

Protozoans



We are excited to begin our Protozoa cluster, focusing on malaria, trypanosomiasis, toxoplasmosis, and leishmaniasis. Despite advances in prevention and treatment, protozoal diseases contribute substantially to the global burden of morbidity and mortality. This cluster has a total of 153 minutes of video and 85 pages of reading spread out over the four lessons. Each lesson has all of the readings, lectures, and additional materials to help you understand the topic. You will have unlimited opportunities to take an untimed quiz after you’ve mastered the material in each lesson, and you have four quizzes to complete in this cluster. (Note: this cluster includes a case study practice quiz, ungraded, which is optional). This cluster kicks off with a close look at malaria vectors and the fascinating research being done on diagnosing, treating, and vaccinating against malaria. This is by far the largest cluster in the course, so you have up to 3 weeks to complete this cluster.
