The first viruses were discovered in 1898 and were identified by their ability to pass through filters that were toos small to allow the passage of bacteria. Since then, scientists have been studying viruses to better understand how to prevent epidemics and pandemics, and research on viruses has revelaed and abundance of information on how living systems works.
