Apparently, Wuhan Flu is about 70% SARS. Which itself is most likely a bioweapon (also targeted at Oriental persons).
The enemy's main objective is not "to paralyze with fear". That's just a means to an end. The enemy's objective is to steal, kill, and destroy. Some are paralysed with fear and indecision and do nothing and get hit by the truck bearing down on them. Others have been taught to bury their head in the sand or put on Ju Junta 2000 Peril Sensitive Sunglasses so they can't see the truck bearing down on them with the same end result.
The way some folks talk keeping a fire extinguisher in the house, learning CPR, or locking your door at night are symptoms of being "paralysed with fear".

But in actuality, implying that people who pay attention to things and who might be taking precautions are in reality "paralysed by fear" and possibly outside the will of God is really no different than what the ten spies did in discouraging Israel from taking action, just in a sort of reverse manner. Thankfully, such people weren't around to successfully discourage Noah as he was hammering nails.
