Understanding Viruses

Explore the Invisible World of Viruses 🦠

Viruses shape human health, agriculture, and even our ecosystems—often without visible warning. Understanding Viruses, Third Edition, by Teri Shors, offers a rigorous and accessible tour through this dynamic field. Written for students and anyone curious about the biology of infectious agents, this edition balances foundational principles with contemporary examples and recent outbreaks.

From Molecular Architecture to Real-World Impact

The text moves logically from viral structure and classification to the molecular biology of infection, host defenses, and the spread of disease. Later chapters focus on specific viruses, including influenza, hepatitis, herpesviruses, HIV, rabies, and poxviruses, while also covering emerging viruses, viruses and cancer, prions, plant viruses, and bacteriophages.

Built for Learning

Each chapter emphasizes key concepts, clinical relevance, and current research. Appendices provide quick-reference properties of human viruses and the Baltimore classification system. A detailed case study on the Ebola epidemic connects course material to one of the most important public health challenges of recent years.

Why This Edition Matters

The third edition updates content to reflect modern virology and includes expanded coverage of new and reemerging viruses. Students in microbiology, nursing, and public health programs will find the presentation clear, while independent learners can follow the progression without a prior background.
