Stomach Virus (stiff Neck) Do I Have The West Nile Virus?

Do I have the West Nile virus? - stomach virus (stiff neck)

I just (again from Nicaragua on Wednesday there never was), and two days before my return, I developed the red dots on their bellies, which are still weak there. Started my ribs hurt when I breathe on Thursday and Friday, when I was very dizzy, headaches, and awoke my fever 100.7. My skin hurts to touch it, as if the muscle pain. The temperature rose to 101,8, but today it is down, my muscles are not as bad, but my neck is stiff, my head feels very heavy and I have a sore throat. Do you think you have caught a virus in Nicaragua?
