I met an amazing number of Jamaicans who had contracted the mosquito borne Chikungunya. Wow! Incredible pain that can persist in the joints for an extended period of time. It's definitely something to avoid so we kept the DEET handy and kept the screens secure as much as possible. We both got a couple of bites, but not sure who were the culprits. Off! wipes are very popular with people I know. I also recommend After Bite, too.
