Basics of Virology
Virus biology, replication, immunity, vaccines, global health, Life Sciences, Microbiology, Biomedical Science, Public Health
Virology is the study of viruses—tiny infectious agents at the frontier between living and non-living entities. This course explores the core principles of virology, beginning with what viruses are, how they are classified, and their evolutionary significance. Learners will study the structural elements of viruses, modes of transmission, and methods by which viruses enter and replicate inside host cells.
The progression of modules details the viral life cycle, replication strategies for DNA and RNA viruses, host–virus interactions, and the molecular basis of infection. The practical impact is emphasised through chapters on immunity, vaccines, antiviral medications, and global health concerns related to viral outbreaks, zoonotic viruses, and viral evolution. Students will become familiar with the scientific methods used to diagnose and study viruses, and will learn how cutting-edge biotechnology uses viruses as genetic tools.
