Fundamentals of Virology and Viral Diseases: From Basic Concepts to Clinical Insights in Infections

Fundamentals of Virology and Viral Diseases presents a clear understanding of viruses, their structure, classification, and role in causing diseases. Viruses are microscopic, acellular particles containing either DNA or RNA, surrounded by a protein coat and sometimes an envelope. They are obligate intracellular parasites that replicate only inside host cells through stages such as attachment, penetration, biosynthesis, assembly, and release. The book outlines the historical development of virology and explains concepts like host specificity and viral evolution.It also covers major viral diseases including HIV/AIDS, COVID-19, and Zika Virus Infection, detailing their transmission, pathogenesis, symptoms, diagnosis, treatment, and prevention. Emphasis is placed on immune system impact, diagnostic techniques, antiviral therapies, and public health measures. The book connects basic virology with clinical practice, highlighting the importance of prevention, early diagnosis, and global disease control.
