[Name] Epideme [Source] Red Dwarf [Symptoms] 
An intelligent virus, originally devised as a smoking cure. It was intended as a cure nicotine addiction, but in practice it rapidly consumes the host before hijacking the body, and then attempting to transfer itself to another suitable host via bites or saliva transmission. If no hosts are available, epideme can force its host into a state of hibernation, encasing the body in a tomb of ice-like material until it detects life nearby and thaws. Epideme steals the knowledge from every host it consumes, which has crafted it into an extremely smart, eccentric and deadly virus.
