Novel Network Approach to Mosquito Control Distribution Yields Insights for a City in Southern Ecuador

Posted on February 24, 2020

GAINESVILLE, FL – Fighting mosquito-borne disease can be costly – in both health and financial resources. While mosquito control is an effective way to combat the spread of diseases like dengue fever, the cost of spraying every house in a city quickly adds up.
