It is the Flu my darling, or some other sort of creeping crud that travels around this time of the year.
WNV does not hide out in your body waiting to pop out. Once you have it, you will know you have it in less than 20 days.
Really, one of the main symptoms to look for with WNV is what I call the googlie eye. (I actually volunteered at a Raptor Rehab starting the year WNV hit Kentucky, it was very scary.)Our director ended up being one of the first five to contract WNV in Kentucky, and we really thought he was going to die by his symptoms and behaviour.
In humans and adults, that was one of the obvious main symptoms. Others for humans were : high fevers, confusion (and I mean SEVERE confusion), muscle weakness (sometimes to the point that you just fall down), severe headaches, stiff neck, or if your eyes become sensitive to light aka googlie eye.
I really thought, with as many headlines this was making that it would only make sense for it to grow bigger and more bad, by spreading to other wildlife, such as deer, and rabbits. But it never did, and all the hype reminded me of the Killer Bee scare years ago...although, I know, WNV is still on the lose killing TONS of birds in all States now.
