TRANSMISSION HETEROGENEITY

OVERVIEW

Over a decade of research on the role of heterogeneity (individual, spatial, temporal) on arbovirus transmission dynamics has unveiled the critical role of specific traits on pathogen transmission. We have developed a novel framework to study the overlapping nature of couplings between functional heterogeneities relevant for vector-borne disease transmission. We argue that research efforts should move beyond considering the impact of single sources of heterogeneity and account for complex couplings between conditions with potential synergistic impacts on parasite transmission. Using theoretical approaches and empirical evidence from various host–parasite systems, we investigate the ecological and epidemiological significance of couplings between heterogeneities and discuss their potential role in transmission dynamics and the impact of control.

FUNDING

2019 - 2021

Emory University MP3 Initiative

The Sum of the Parts: Understanding the Interaction between Individual and Population Immunity to Dengue, Viral Diversity, and Transmission Dynamics

This project will integrate high resolution immunological information on recent and prior dengue virus infections with whole-genome sequencing and spatial analysis with the ultimate goal of developing susceptibility landscapes that may help predict the risk of future virus transmission.

2014 - 2019

National Institutes of Health

Quantifying Heterogeneities in Dengue Virus Transmission Dynamics

NIH/NIAID/P01AI098670

The goal of this project is to quantify heterogeneities in human variables that affect dengue virus transmission dynamics and prevention by studying people across the entire continuum of disease, including people with clinically inapparent and mild infections.

Our Role: Co-Investigator

National Science Foundation

Macro-Ecology of Infectious Disease

NIH/NSF/FIC (EEID) 1316223

The goal of this project is to extend the ecological discipline of macro-ecology to the study of parasites and rules defining their distribution, emergence, and epidemiological role.

2016 - 2018

Emory University Research Council (URC)

Urban Ecology of West Nile Virus in Atlanta, GA

Emory University Research Council Grant

The goal of this project was to characterize the role of host and mosquito species community composition, spatial heterogeneity, and seasonality on West Nile virus transmission dynamics.
