The virus-host relationship describes those interactions which occur when a virus infects a cell. Infection converts the metabolically inert virion into the dynamic, metabolically active intracellular form of the virus. A common outcome of infection is multiplication of the virus with the concomitant death of the host cell. This is the productive cycle of virus infection. There are alternative modes of interaction in which the virus exists with the host cell in a long term, non-productive association which is non-lethal to the cell.
