By comparing experimental Zika transmission data to annual […]

Effects of changes in temperature on Zika dynamics and control

RYAN – Effects of changes in temperature on Zika dynamics and control Article first published online: 05 MAY 20212 Journal of the Royal Society Interface DOI: 10.1098/rsif.2021.0165 ABSTRACT: When a rare pathogen emerges to cause a pandemic, it is critical to understand its dynamics and the impact of mitigation measures. We use experimental data to […]

Flying Under the Radar

GAINESVILLE, FL – University of Florida Associate Professor of Medical Geography Dr. Sadie Ryan (Emerging Pathogens Institute, Quantitative Disease Ecology & Conservation Lab) spoke with WUFT News about vector-borne disease in the time of coronavirus in Flying Under the Radar. “It’s not like mosquitoes went on hold because of COVID,” she said. “The message needs to stay alive.” […]

Machine Learning Predictions of Dengue Patients Outcomes Yield Promising Results

GAINESVILLE, FL – Helping patients with dengue can be challenging – especially in countries with multiple diseases spread by mosquitoes. Dengue, chikungunya, and Zika are viruses spread by the same type of mosquito; all three viruses are present in Ecuador and many other countries in Latin America and the Caribbean. Patients infected with one of […]

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, […]
