Virology is the science of viruses and the diseases they cause. Many virology experts have studied the way the Covid-19 virus mutates and spreads.
The field of virology is vital to understanding infections caused by viruses — not only Covid-19 and influenza, but also rubella, hepatitis, and AIDS. Scientists who specialize in virology are virologists, and they research the way viruses behave, change, and spread between people or animals. Virology experts are also key to developing cures and treatments for viral illnesses. Virology derives from virus and its Latin root, which means "poison."
