Pat yourself on the back if you answered "c". Chikungunya is a tropical disease transmitted by the daytime bite of a mosquito. Dubbed "break-bone disease" because of the joint pain it causes, it is similar to malaria. Its symptoms are usually more severe but less long-lasting. Chikungunya appeared for the first time ever in Haiti last year, apparently via mosquitoes carried in inadvertently by visitors. All the MBB staff in Haiti suffered from it for a few days before it mercifully ebbed.
