Virológia is the scientific study of viruses and virus-like agents. It is a sub-discipline of microbiology and an important field of medicine, veterinary science, and botany. Virologists investigate the structure, classification, evolution, and mechanisms of infection and replication of viruses. They also study the diseases viruses cause and the methods for their prevention and treatment.

Viruses are obligate intracellular parasites, meaning they can only replicate inside living host cells. They possess a simple structure, typically consisting of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell membrane. The study of virology is crucial for understanding infectious diseases, from common colds and influenza to more severe conditions like HIV/AIDS and COVID-19.

Key areas within virology include the development of vaccines and antiviral drugs, diagnostic techniques for identifying viral infections, and understanding the complex interactions between viruses and their hosts. Research in virology also contributes to fields like molecular biology and genetics, as viruses are often used as tools to study cellular processes. The ongoing emergence of new viral threats necessitates continuous research and advancement in the field of virology.
