Where were they? If they were in the Caribbean there is a nasty bug down there that has those systems and if the South, it could be he was bitten by that "new" mosquito. Both have those systems. Sorry for him.
They went to a campground in TN called "NickaJack" or something like that but he got sick as soon as they got there. Whatever bit him did so at their home a little south of Huntsville.
