Virus-host interaction is a broad research area that focuses on understanding how viruses interact with their host organisms. This includes studying the molecular mechanisms by which viruses infect host cells, replicate within them, and evade host immune responses. Researchers in this field also investigate how host cells respond to viral infections, including the development of antiviral strategies and immune responses. Overall, virus-host interaction research aims to uncover the intricate relationships between viruses and their host organisms, with the ultimate goal of developing new therapies and interventions to combat viral infections. Topics of study in this field can range from the molecular details of virus replication to the evolutionary dynamics of virus-host coevolution.
