I got West Nile last summer. Symptoms are very different depending on the individual, but a few things seem to be common. First, before you know you are sick, you break out in a rash. It seems most people get some form of the rash. Mine was horrible, I couldn't imagine what it was. Then I got flu like symptoms, but my worst symptom was fatigue. In my case the fatigue has persisted for coming up on one year. My doctors and specialists (infectious disease folks) say what I have now is chronic fatigue that was instigated by the virus.
I know of 2 other cases where the patient had partial paralysis of the legs that persisted for several months, while some people get it and don't even know they had it. The range of symptoms is huge and varied. There is a LOT the doctors don't know about West Nile virus. I hope your husband doesnt have it. I don't know if I'll ever get over the condition I got from this thing.
