Practical Examples

1. The development of penicillin

   Tregoning describes Alexander Fleming's accidental discovery of penicillin and the ensuing efforts by scientists and industry to mass-produce it. He explores how this breakthrough revolutionized the treatment of bacterial infections and saved millions of lives, while also detailing the collaborative nature of scientific progress.

2. How vaccines work

   A clear, narrative walkthrough of how vaccines trigger the immune system to recognize and neutralize pathogens. The book uses historical and contemporary vaccine development as examples, demonstrating vaccine efficacy in eradicating or controlling diseases such as smallpox and polio.

3. The SARS-CoV-2 pandemic

   Recent events are dissected to show how quickly new pathogens can spread in a globalized world. Tregoning examines the global response, the role of scientific cooperation, and the challenges faced in developing effective diagnostics, treatments, and vaccines amid uncertainty.

4. Antibiotic resistance

   The book provides an in-depth discussion about the causes and consequences of antibiotic resistance, incorporating real-world examples where overuse and misuse of antibiotics led to the emergence of tough, untreatable infections. Tregoning highlights the urgent need for novel therapies and responsible stewardship.

5. The 1918 Influenza Pandemic

   Tregoning uses the deadly Spanish Flu as an example to explain the societal impact of pandemics, from overwhelmed healthcare systems to misinformation and public fear. He draws parallels to current challenges in pandemic preparedness and response, emphasizing lessons learned and forgotten.

6. Zoonotic spillover

   The book describes how pathogens jump from animals to humans, citing examples like Ebola, HIV, and coronaviruses. Tregoning discusses the factors that make zoonotic spillovers more likely, including changing land use and global trade.

7. Citizen science and public engagement

   An encouraging account of how ordinary people contribute to disease surveillance, data collection, and even problem-solving via crowdsourcing efforts. The book highlights successful initiatives, such as influenza tracking apps and community reporting systems.

8. The politics of pandemics

   Through examples like the handling of HIV/AIDS and COVID-19, Tregoning shows how political decisions and public trust (or lack thereof) can have profound impacts on disease control efforts, vaccine rollouts, and mortality.

9. CRISPR and new therapies

   He explores how techniques like CRISPR gene editing have been repurposed from bacterial defense systems to revolutionary medical tools, giving new hope for combating certain infectious diseases and diagnosing them more rapidly.
