This is the all-time cumulative hit count for a virus name appearing in the all-time top-viruses table. Comparing this all-time count to the same virus's current-period count tells an admin whether a threat is newly resurgent or just adding modestly to an already-large historical tally, which changes how urgently it needs investigating. For example, an all-time count of 50,000 versus a current-period count of only 2 would indicate a threat that was once a major outbreak but is now largely dormant on this gateway.
