Virologists are medical doctors that oversee the diagnosis, management and prevention of infection. They’re also scientists, who may drive research on various aspects of viruses. A virologist may be both a scientist and a physician. Virologists study viruses that affect humans, animals, insects, bacteria, fungi and plants, in community, clinical, agricultural and natural environments. Virology is the scientific study of viruses – sub microscopic, parasitic organisms of genetic material contained in a protein coat – and virus-like agents. It focuses on the following aspects of viruses: their structure, classification and evolution, their ways to infect and exploit host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. Virology is a subfield of microbiology.
