Chikungunya, or Chick-V, is spread by infected mosquitoes, and they can only become infected by biting an infected and contagious person. A person can only be contagious for about a week. We have not heard of any cases in Negril or elsewhere on the island since the last week of January/first week of February. I am not discounting what you had, but there are the usual flus going around Negril like the ones in North America. Just yesterday I was talking with two Boardies who said "we probably brought it down" as one was still sick. Lisa (Bnewb) has been down this past week with the flu, and with it came a rash. But it was not Chick-V.
To quote a friend who contracted Chick-V back in December when it was at its height in Negril, "Chick-V is not something you think you have. You KNOW you have it." The most common symptoms are fever and severe joint pain, often in the hands and feet. If you felt normal flu-like aches, chances are you had the flu that has been going around town. Sorry about you both being sick, it does suck on vacation, but from your description, I think it sounds likes the same flu Lisa had.
