The definition of a retrovirus here seems rather long and detailed and, while correct, I doubt that much (if any) of the information appeared in the episode cited. Should it be trimmed down significantly? -- Renegade54 17:30, 12 August 2006 (UTC)

In TNG:"Future Imperfect" Beverly Crusher describes Will Riker's memory loss as the result of a retrovirus. This scene later proves to be generated by the Romulan equivalent of a Holodeck.--Samuel Pengraff 18:57, July 4, 2010 (UTC)
