A survey of 219 patients showed that 11 percent suffered internal hemorrhage, plasma leakage, shock, and thrombocytopenia (low platelet count in the blood).
A controversial way to prevent dengue is to kill off the mosquito population with genetically modified insects. Bijal P. Trivedi reported in the November 2011 issue of Scientific American that testing is already underway for a gene mutation that kills the biting females of one species of mosquito, while leaving the males healthy enough to compete with unmodified males.
