Global Health and Tropical Medicine Course (GHTM)

Learn the basics of practicing tropical medicine in low-resource settings

CHSC’s Global Health and Tropical Medicine (GHTM) Course provides an overview of diagnosing and treating tropical diseases in a case-based format, using evidence-based best practices.

Our tropical medicine course faculty have decades of combined experience practicing in low-resource settings. Students will learn the necessary skills for short and long-term global health work.

The course is conducted virtually over Zoom LIVE and spans six weeks. Sessions will be held on Monday and Wednesday evenings from 5:00 to 7:00 PM Central Time. The last day of the course is a Saturday from 9:00 AM to 1:00 PM.

Virtual attendance is required to meet the course’s continuing education certification requirements, and we cannot accommodate any exceptions. This course offers 26 continuing education credits if all requirements are met.

Sarah is a board-certified ER physician who graduated from the Virginia College of Osteopathic Medicine and then completed residency training at the Geisinger Health System in Danville, PA in 2011. She was awarded her PhD from Virginia Tech in Health Promotion with an emphasis on international health and completed her dissertation on HIV awareness and education in El Salvador in 2009. She has worked extensively around the world in low resource settings and has been a part of medical care in over 20 different countries, having engaged in several disaster responses including natural disasters and infectious outbreaks.

She has completed her Masters in Disaster Healthcare from the University of South Wales and has a passion to see high-quality care delivered, regardless of the setting. Her goal is to elevate the care that mission hospitals deliver through this new partnership with CHSC. “Quality care everywhere is achievable, and we exist to come alongside others to make this a reality. For we are all made in the image of God and what better way to honor that than to strive to deliver the very best care possible in each setting.”
