It then discharges its DNA or RNA, which smashes the original genetic material and functioning of the cell. But before the victimized cell expires, it leaves or releases more of that virus. The virus multiplied in such a fashion impedes the growth and working of other healthy cells too, so much so that sooner or later the entire body comes in its grips.
