Predators, environment and host characteristics influence the probability of infection by an invasive castrating parasite

Not all hosts, communities or environments are equally hospitable for parasites. Direct and indirect interactions between parasites and their predators, competitors and the environment can influence variability in host exposure, susceptibility and subsequent infection, and these influences may vary across spatial scales. To determine the relative influences of abiotic, biotic […]

Anticipating the emergence of infectious diseases

In spite of medical breakthroughs, the emergence of pathogens continues to pose threats to both human and animal populations. To address this challenge, members of the Rohani lab, along with a collaboration with John Drake, present candidate approaches for anticipating disease emergence prior to large-scale outbreaks. Through use of ideas from […]

Assessing real-time Zika risk in the United States

Steven Bellan, a biostatistician from UGA’s College of Public Health, developed a quantitative framework for real-time ZIKV risk assessment that captures uncertainty in case reporting, importations, and vector-human transmission dynamics. His findings, published recently in BMC Infectious Diseases, reveal that though large metropolitan regions of the United States (such as the […]

New model maps likelihood of Ebola spillovers by location and month

Ecologists at the Center for the Ecology of Infectious Diseases have developed a model that maps the likelihood of Ebola virus “spillovers”—when the virus jumps from its long-term host to humans or animals such as great apes—across Africa on a month-by-month basis. Their findings, published recently in the journal Emerging […]

More mosquito species than previously thought may transmit Zika

Zika virus could be transmitted by more mosquito species than those currently known, according to a new predictive model created by ecologists at the University of Georgia and the Cary Institute of Ecosystem Studies. Their findings, published today in the journal eLife, offer a list of 26 additional potential candidate […]

Waiting time to infectious disease emergence

Bifurcation delay is a phenomenon that occurs when dynamical systems go through a critical transition. Bifurcation delay occurs because the state of the system may continue to follow the path provided by one basin of attraction even after the stability landscape of the system has changed. For emerging infectious diseases, […]

Global patterns of zoonotic disease in mammals

The majority of infectious diseases currently emerging in humans originated in mammals. Yet we still know very little about the global patterns of mammal-to-human pathogen transmission. As a first step, researchers at the Cary Institute of Ecosystem Studies and the University of Georgia have assembled world maps of what’s on record […]
