Viral diversity is the study of the wide range of viruses that exist in the world. Viruses are diverse in terms of their genetic makeup, host specificity, transmission methods, and impact on their hosts. Understanding viral diversity is important for predicting and preventing disease outbreaks, developing treatments and vaccines, and studying the evolution of viruses. Research in viral diversity involves identifying and characterizing new viruses, studying their interactions with hosts and the environment, and analyzing their genetic diversity and evolution.
