Why weren't neighboring countries affected by Haiti Quake?

Why arent neighboring countries such as the Dominican Republic and Jamaica affected by the quake, or are they merely not talked about since Haiti was already an economic disaster already?
Update: Ahh, ignore the second already...
Update 2: Thank you michael, and for those of you who need some touching up on your geography, the dominican republic shares a border with Haiti
Update 3: Haha, @ peacepoet

I wouldn't doubt it, i know they used to have zombies lol
