How Germs Spread and How to Stay Healthy

Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive introduction to germs, scientifically known as pathogens, and their impact on human health. Hosted by Kaylee, the lesson breaks down the microscopic world of disease-causing organisms, distinguishing between viruses, bacteria, parasites, and fungi. It carefully explains that while some microorganisms cause sickness, others (like bacteria in yogurt or mushrooms on pizza) can be beneficial, helping students understand the complexity of the microbial world rather than viewing all "germs" as bad. The video details the four primary modes of pathogen transmission: food and water contamination, insect bites, direct contact between humans, and indirect contact through surfaces. It introduces essential scientific vocabulary such as "contagious," "infectious disease," and "transmitting" in an accessible way. Specific examples like Salmonella, malaria, the flu, and athlete's foot are used to illustrate how different pathogens operate and spread within the human body. For educators, this resource serves as an excellent foundation for health and science units focusing on hygiene and disease prevention. It offers practical, actionable advice for students, such as the proper technique for handwashing (20 seconds with warm soapy water) and the importance of not touching one's face. The video also touches on building a strong immune system through sleep, exercise, and nutrition, making it a holistic tool for teaching students how to take ownership of their personal health and safety.
