Many people only think about health when they are sick. This course provides the foundational knowledge necessary to understand the biological mechanisms behind disease and how to proactively protect your health. By the end of this course, you will understand the differences between infectious and non-infectious diseases, the basic principles of immunology, and effective public health and personal strategies for prevention. What you'll learn: * Understand the fundamental classifications of human diseases, including acute, chronic, infectious, and non-communicable conditions. * Learn the roles of various pathogens (viruses, bacteria, fungi, protozoa) and how they cause illness in the human body. * Master the foundational concepts of the immune system and the body’s natural defense mechanisms against disease. * Apply principles of hygiene and vaccination to effective disease prevention and community health. * Examine the critical role of lifestyle factors and the gut microbiome in long-term health and immunity. * Analyze the challenges posed by antimicrobial resistance and its impact on modern medicine. This course begins with key terminology and definitions related to health and disease, gradually building up to the mechanisms of infection, the immune response, and practical prevention strategies. Learners will engage with written explanations and practice exercises to solidify their knowledge. This course is designed for absolute beginners interested in biology, health science, or general wellness. No prior knowledge of medicine or biology is required to start.
