The scientific study of viruses is referred to as virology. This branch of microbiology focuses on the structure, classification, and evolution of viruses, as well as their effects on host organisms. Virologists examine how viruses infect cells, replicate, and interact with the immune system. The study of virology is particularly significant in understanding viral diseases, developing vaccines, and improving treatments. Recent global health challenges, such as the COVID-19 pandemic, have highlighted the importance of virology in public health and disease prevention.
