Virus research focuses on studying the structure, function, replication, transmission, and impact of viruses on various organisms, including humans, animals, and plants. Researchers in this field work to understand the mechanisms by which viruses infect cells, evade the immune system, and cause disease. They also investigate how viruses can be controlled and treated through vaccines, antiviral drugs, and other interventions. Additionally, virus research plays a crucial role in the development of diagnostic tests and surveillance programs aimed at monitoring viral outbreaks and preventing the spread of infectious diseases.
