A simple and minor issue that is blown way out of porportion by the media when there is nothing else to report. The public becomes deathly worried about something that is no more dangerous than the common flu.
ie. SARS, Bird Flu, Mad Cow, Killer Bees, etc.
Person A: "Did you hear about the SARS epidemic?"
Person B: "Epidemic? It's killed less people than the flu. Its nothing more than slow news day virus."
