The Health Protection course is the fourth instalment of the wider Foundations of Public Health Practice specialisation from Imperial College London's Global Master of Public Health (MPH). The scope and content of this course has been developed from the ground up by a combined team of academics and practitioners drawing on decades of real-world public health experience as well as deep academic knowledge. Through short video lectures, practitioner interviews and a wide range of interactive activities, learners will be immersed in the world of public health practice. Designed for those new to the discipline, over three modules (intended for three weeks of learning), learners will become familiar with the scope, principles and nuances of health protection in the context of public health practice. Beginning with the basics of Water, Sanitation and Health (WASH) based interventions, the course will introduce learners to the science and principles of practical microbiology, before examining vaccines, incident management and the threat posed by a wide range of manmade and natural environmental threats. By the end of this course, learners will be familiar and conversant with core health protection principles and approaches, and confident in discussing health protection issues when they move into practice.
