I find it suspicious that i've heard zilch of it here in Denmark. Nothing in the TV, radio or newspaper. And the news here are usually looking for disasters in foreign countries to plague us with, because there's not enough bad stuff going on here. >.>
For all i know, this could be a serious threat or just another widespread april fools joke, i'm not going to care about it anyhow, since i'm not infected. And because of the current date. =P
