This paper critically evaluates the foundational principles of virology, focusing on viral transmission, which underpin the broader scientific claims about the existence and pathogenicity of viruses. A thorough examination reveals significant empirical gaps and methodological limitations. Historical and contemporary studies are reviewed to highlight the lack of consistent evidence supporting person-to-person viral transmission, often relying on proxies such as molecular detection rather than direct causality. By addressing these shortcomings, this paper challenges the conventional paradigms of virology and their implications for public health strategies, including vaccination and quarantine measures. This work aims to foster a critical reassessment of virological methods and assumptions, promoting a more robust scientific framework for understanding diseases.
