This book proposes a concrete path to bring an end to pandemics and achieve a world without infectious diseases, suggesting an escape from the long history of infectious diseases that have brought misery and confusion to humanity. The book presents an Mikawa-Kase-AQIP model to illuminate the generation of infection units originating from the lungs, where viral proliferation occurs. It further elucidates the theoretical distribution of viruses entrapped within aerosol particles. It is entirely possible to avoid infection using today's science and technology, if we all understand, share, and implement an air ventilation approach which will stop viruses from entering the body. The challenge to eradicate future pandemics must be confronted now. The aim in this book is to present the answer.
