International Scholar Speaks about Aedes Aegypti Mosquito at USciences

Published on February 24, 2020

Elizabet L. Estallo, PhD, from the Institute of Biological and Technical Investigations at the National University of Cordoba in Argentina spoke to students during an event on February 13.

Dr. Estallo, a collaborator of Michael Robert, PhD, assistant professor of mathematics, physics and statistics at USciences, spoke about the influence of environmental changes including climate change on the spread of dengue in Cordoba, Argentina. 

More about their work:

Argentina is located at the southern range of arboviral transmission by Aedes aegypti (a small container-breeding mosquito that transmits dengue, Zika, chikungunya, yellow fever, and other viruses) and has experienced a rapid increase in arbovirus transmission in recent years. We have been investigating recent arbovirus transmission in the temperate area of Córdoba city by developing a series of mathematical and statistical models. With the aid of species distribution models for Ae. aegypti,we have generated risk maps to identify vulnerable areas that exhibit conditions appropriate for vector development in the city area and how land cover could be influencing Ae. aegypti populations. We have also developed models that use remote sensing data to understand the impacts of environmental variables on oviposition (egg-laying) activity of mosquitos, temporal dynamics of the mosquito, and dengue cases. We present the results of these studies as well as findings from statistical analysis of the first 9 years of an entomological surveillance work that began in the temperate Córdoba following the emergence of dengue in 2009. Our findings taken together suggest increasing the risk of arbovirus transmission in this temperate region. These results can guide targeted vector control interventions and the development of climate services for the public health sector to reduce the burden of arboviral diseases.
