Insecticide Resistance Threatens the Control of Mosquito-Borne Disease in Ecuador

GAINESVILLE – In the battle against vector borne disease, mosquito control using insecticides is an essential tool. But what happens when that tool starts to fail, and how do you know it? Insecticides are regularly used by public health agencies to reduce populations of blood-sucking mosquitoes. Effective control programs are important to public health because, […]

New maps show where mosquitoes will invade Ecuador’s Andes mountains

GAINESVILLE – Blood sucking insects such as the Yellow fever mosquito, Aedes aegypti, are more than just a nuisance in Ecuador, they also spread diseases such as dengue fever, chikungunya and Zika. A warming world means that public health officials must decide where to direct surveillance and mosquito control efforts not only today, but also […]

Social-Ecological Factors Drive Dengue and Mosquito Presence in the Galapagos

GAINESVILLE, FL – With its turquoise waters and abundant wildlife, Ecuador’s Galapagos Islands have long been a vacation dream of many. Tourist guides highlight playful sea lions and giant tortoises, but they do not talk about the mosquitoes. For the more than 30,000 people who live there, emerging epidemics of mosquito-borne disease such as dengue, […]

Geography Grad student receives best PhD paper at the 2018 SEDAAG annual meeting!

Second-year PhD student Stephanie Mundis of the Quantitative Disease Ecology & Conservation Lab, advised by Dr. Sadie Ryan, was recognized for her paper and presentation at the 2018 SouthEastern Division of the American Association of Geographers. Her presentation, “Spatial analysis of pyrethroid resistance genotypes in Aedes aegypti mosquitoes in Florida,” focused on spatial patterns in […]

Temperature drives Zika virus transmission: evidence from empirical and mathematical models

UF Researchers Refine Zika Transmission Models

GAINESVILLE, FL – A University of Florida Medical Geography researcher recently participated in a study that found that current estimates of Zika virus transmission vastly over predict its possible range. Temperature is a major driver of vector-borne disease transmission, but current transmission models rely on untested assumptions about life history of Zika infected Aedes aegypti […]

UF Researchers Make New Strides in Predicting Dengue Fever Outbreaks

GAINESVILLE, FL – Medical Geography researchers from the University of Florida recently participated in a study that successfully predicted dengue fever outbreaks on the Caribbean island of Barbados, using climate data. This paper is part of a special issue of PLOS MEDICINE, focusing on the impacts of climate change on health, and is a result […]

Farewell to summer MedGeo researcher

This summer, Geography’s Ryan Lab and the Emerging Pathogens Institute were proud to host Lauren Fregosi as a summer research intern working on Dr. Sadie Ryan‘s National Science Foundation’s Ecology and Evolution of Infectious Diseases (NSF EEID) grant. The internship, which was offered through the NSF Research Experience for Undergraduates (REU) program, was focused on modelling approaches […]
