Andrews Researchers Study Fever in Peru

Disease ecologists working in the Amazonian city of Iquitos, Peru, have quantified for the first time how a fever affects human mobility during the outbreak of a mosquito-borne pathogen. The findings were published by Proceedings of the Royal Society B.

"When you are sick with dengue, or another illness causing fever, your behavior can change," says Gonzalo Vazquez-Prokopec, an assistant professor in Emory University's Department of Environmental Sciences, and senior author of the study. "We've found that people with a fever visit 30 percent fewer locations on average than those who do not have a fever, and that they spend more time closer to home. It may sound like stating the obvious, but such data have practical applications to understand how human behavior shapes epidemics. No one had previously quantified how a symptom such as fever changes mobility patterns, individually and across a population, in a tropical urban setting like Iquitos."
