Explanation

The branch of science that deals with the study of viruses is called virology. Virology is a specialized field of microbiology that focuses on understanding the structure, classification, genetics, and replication of viruses, as well as their interactions with host cells and the diseases they cause. This field also studies how viruses spread, how the immune system responds to them, and how antiviral drugs and vaccines can be developed to prevent or treat viral infections. Since viruses occupy a unique position at the border of living and non-living entities, virology plays a crucial role in medicine, biotechnology, and public health.
