Tropical Parasitology: Protozoans, Worms, Vectors and Human Diseases

The Trematodes cluster focuses on schistosomiasis and fascioliasis. It is estimated that almost 60 million people are infested with trematodes globally. This cluster has a total of 79 minutes of video and 31 pages of reading spread out over the two lessons. You will have unlimited opportunities to take an untimed quiz after you’ve mastered the material in each lesson, and you have two quizzes to complete for this cluster. This cluster begins by looking at schistosomiasis, a common intravascular infection caused by parasitic trematode worms in contaminated water.

The Nematodes cluster focuses on filariasis, ascariasis, hookworm, and strongyloidiasis. Nematode infestations may impact up to 185 million people in recent estimates of the global burden of disease. This cluster has a total of 90 minutes of video and 8 pages of reading spread out over four lessons. 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 for this cluster. This cluster kicks off by examining lymphatic filariasis and the fundamental need for compassion as a core value in global health practice.

We are now into our final cluster, Ectoparasites, focusing on fleas, ticks and mites, lice, and pathophysiology of infestation with ectoparasites. In addition to causing annoying symptoms on their own, ectoparasites may be important vectors of human disease. This cluster only contains one lesson (Ectoparasites) and has 30 minutes of video and 33 pages of reading. You will have unlimited opportunities to take an untimed quiz after you’ve mastered the material, and you have one quiz to complete for this cluster We begin by looking at how to prevent Lyme disease through protective measures, tick reduction, and various vaccines for humans, ticks, and even reservoirs.

The final exam is a graded 3-part exam, and each part includes information from all of the disease clusters covered throughout the course. The final exam consists of 45 questions, in total. You will have unlimited attempts for each part of the final exam, with the highest scoring attempt counting toward the course grade. The final exam will contribute 60% to your total course grade (with each part of the exam having a weight of 20%).
