That is an incredible statement. I would think you’d want a symbol that represents danger to be intuitive.
Probably wanted to avoid something you could be used to, or confuse or dilute with some other form of danger. I think they wanted to make sure this particular form of danger was known to be especially silent, horrible, and potent.
It did not turn out meaningless though. Looks like a virus with spikes.
