A machine-learning approach to track how yellow fever mosquito moves through the environment The yellow fever mosquito ( Aedes aegypti) is a main vector of deadly diseases like dengue fever, chikungunya, and the Zika virus, which result in hundreds of thousands of deaths worldwide each year. Because Ae. aegypti prefers to bite humans and there are no vaccines for many of these diseases they carry, developing methods to control these insects is imperative in the fight to control illness. In a study recently published in Proceedings of the National Academy of Sciences, a Yale-led research team developed a new method to track how
