Health: Viruses & Fungi (HIV, Ebola & Ash Dieback) | GCSE Biology

How do viruses and fungi cause disease — and why are viral infections so hard to treat?In this episode of GCSE Science Simplified, we complete our Pathogens Explained series by focusing on fungal and viral pathogens. Using clear GCSE-level explanations and key specification examples, we explore how diseases like Chalara ash dieback, HIV/AIDS, and Ebola affect organisms and disrupt normal biological processes.You’ll learn:The GCSE definition of a pathogenHow fungal diseases damage tissues and transport systems in plantsHow viruses invade host cells and cause diseaseWhy HIV destroys white blood cells and leads to AIDSHow Ebola causes haemorrhagic feverKey differences between fungal and viral infectionsIdeal for GCSE Biology revision, Health and Disease topics, and students preparing for exam questions that require clear explanation and application.🎧 Next up: How the body defends itself — barriers, immune responses, and vaccinesGCSE Biology, Pathogens, Viruses, Fungi, HIV, AIDS, Ebola, Chalara Ash Dieback, Communicable Disease, Health and Disease, GCSE Revision, Biology Podcast, Science Revision, GCSE Science Simplified
