We live in a world shaped by infectious disease. What does that mean? Over the course of five units, let’s explore the history and science of diseases like smallpox and the common cold to better understand how our own bodies work and what we can do to avoid dying of future plagues.
Unit 1
Why should we care about infectious disease?
Lesson 1: What is an infectious disease and why do we care?
Lesson 2: How infectious disease has molded history – including ours
Lesson 3: Bacterial structures
Lesson 4: Viral sizes and structures
Lesson 5: So why aren’t we always sick? Our body’s defenses
Bacterial Pathogen Pronunciation Station
Visit the Bacterial Pathogen Pronunciation Station site to listen to the pronunciations of most, if not all, of the microbial names you will encounter throughout ID.
Unit 2
What does it mean to have an infectious disease?
Lesson 1: Infectious Disease Detectives – Typhoid Mary
Lesson 2: What are the patterns of infectious disease?
Lesson 3: How do infectious diseases spread?
Lesson 4: How can we prove infection causes disease?
Lesson 5: Do bacteria cause stomach ulcers? Applying Koch’s postulates
Unit 3
When does a microbe become pathogenic?
Lesson 1: The zoo in you – our microbial ecosystem and Ebola
Lesson 2: Reservoirs and vectors – Lyme disease and Malaria
Lesson 3: Invasion of the body snatchers – Fighting back after infection
Unit 4
How do pathogens make us sick?
Lesson 1: Why we feel sick – how pathogens cause direct and indirect damage
Lesson 2: Toxins – Botox, tetanus, hamburger disease, and MRSA
Lesson 3: How do bacteria adapt to become pathogens? – The adaptation auction
Lesson 4: How viruses make us sick – Viral replication
Lesson 5: How do viruses adapt? – Antigenic shift and drift and the flu pandemic
Lesson 6: Designing an antiviral drug – The challenge of HIV
Unit 5
How do we get better?
Lesson 1: Our body’s barriers – the innate immune system
Lesson 2: Evolving pathogens – the adaptive immune system
Lesson 3: Evolving pathogens – our body’s responses – B and T cells
Lesson 4: Our body’s responses – putting it all together!
Lesson 5: What makes a good vaccine?
