Students anticipating a career in preventing and treating diseases and conditions throughout the world will find this course interesting. We will begin by sharing our backgrounds and interests, to guide future discussions. We will review basic epidemiological concepts that will appear in the scientific studies presented later in the course. We will then explore several diseases and conditions that commonly challenge global public health. Topics will include malaria, polio, parasites, tuberculosis, pandemic preparedness, and general health conditions. Geographic areas will include Haiti, Iraq, Kosovo, Nigeria, and the United States. I will share my real-life experiences seeing patients and studying these diseases scientifically. Guest speakers will participate as well, on such topics as coronavirus and Ebola. Students will be expected to prepare a presentation on a selected infectious disease or health condition affecting a developing area of the world, based on prior experience or current interest. I hope this course inspires you to become involved in international public health and medicine.
