A study in Iquitos, Peru, is focusing on how asymptomatic human carriers contribute to the spread of dengue fever, transmitted by the Aedes aegypti mosquito. "This information is important," says Emory University disease ecologist Gonzalo Vazquez-Prokopec, "because Latin America is more than 80 percent urban and the Aedes aegypti mosquito is in every town."
