I have never heard this term before.
What does it infect and what are the symptoms and side effects?
Is this just some made up name to sound scary in the media?
What does /sci/ think of this? Im sure theres doctors on here.
I think its just a new form of the flu and the media is calling it something scary to push more vaccines.
Pic semi-related.
