Orion flu
From Tardis Wiki, the free Doctor Who reference
Orion Flu was a dangerous disease, fatal and resistant to all forms of treatment.
Commander Paul Keele of Dark Space 8 contracted Orion flu while trying to stop a silicon-based lifeform from enslaving all carbon-based life. Despite Dr Eleanor Harcourt's best efforts, he died from it. (AUDIO: Bang-Bang-a-Boom!)
