Rick - I did a lot of research after my bout with dengue. I thought I had caught something on the plane which is common in the closed cabin atmosphere. When I stated my symptoms the doctor knew better. I had a hell of a time keeping my body temperature under 104F. The doctor had blood tests taken to confirm his belief and my white blood cell count was only a fraction of normal. For me it was a 3 day incubation period then a week of high fever, the second week with the rash and pains wasn't too bad because I knew they weren't going to kill me.
Prevention is your friend with dengue!!! I know some people sail thru it without much difficulty yet others get more severe cases and for about 1% it proves fatal.
