The scientific study of viruses is known as virology. This field encompasses the examination of the structure, classification, evolution, and behavior of viruses, including their interactions with host organisms. Virologists investigate how viruses replicate, spread, and cause diseases in humans, animals, and plants. This knowledge is crucial for developing vaccines, antiviral therapies, and understanding viral epidemiology. Virology plays a significant role in public health, especially in responding to outbreaks of infectious diseases caused by viral agents.
