Superspreading in macroparasites

Maya Risin, a student from Emory University, worked with Dr. John Drake to study superspreading in macroparasites. Abstract: It is widely understood that host populations harboring macroparasites, which include parasitic helminths and arthropods, typically exhibit skewed infection burdens that give rise to “superspreading”. On the individual level, concurrent infections by multiple parasitic species within an individual

Environmental variability and mosquito-borne disease

Karin Ebey, a student from Eckerd College, worked with Dr. Kyle Dahlin and Dr. John Vinson on modelling the effects of demographic and environmental noise on mosquito-borne disease. Abstract: Mosquito-borne diseases are a significant and growing public health burden globally. Predictions about the future spread and impact of mosquito-borne disease outbreaks can help inform direct control

Who infected whom? Creating a database of transmission trees for comparative outbreak analysis

Juliana Taube, a student at Bowdoin College, worked with Paige Miller and Dr. John Drake. Abstract: Transmission trees contain valuable details about who infected whom in infectious disease outbreaks. We created a database with 81 published, standardized transmission trees consisting of 12 directly-transmitted pathogens (mostly viruses). We also demonstrated how the database could be used

Age-structured model for Tuberculosis intervention planning

Kennedy Houck, a junior from Ursinus College, worked with Paige Miller in the lab of Dr. John Drake to study age-based interventions for Tuberculosis. Abstract:  Tuberculosis (TB) represents a widespread public health concern.  The World Health Organization’s “End TB Strategy” has set the goal for global TB eradication by 2050.  Previous studies have suggested that

Differences in age distribution patterns in urban and rural counties of São Paulo state, Brazil

Magdalene Walters, a student from the University of Notre Dame, worked with Dr. John Drake to study the age distribution of a measles outbreak. Abstract:  In 1997, São Paulo, Brazil experienced a measles outbreak with an unusually high average age of infection. It has since been hypothesized that this high age of infection was due

Visualizing the Effect of Interventions during the 2014-2015 West Africa Ebola Outbreak

Timothy Wildauer, a student from Bethany Lutheran College, worked with Dr. John Drake to test new methods of determining time of infection for Ebola patients. Abstract: Data recorded during the 2014-2015 West Africa Ebola Outbreak indicates when patients presented themselves at a hospital for treatment. However, to know if interventions were successful, we need to

Protective Population Behavior Change in Outbreaks of Emerging Infectious Disease

Evans Lodge, a student from Calvin College, worked with Dr. John Drake to measure how human behaviors change during disease outbreaks. Abstract: In outbreaks of emerging infectious disease, public health interventions aim at increasing the speed with which infected individuals are removed from the susceptible population, limiting opportunities for secondary infection. Isolation, hospitalization, and barrier-nursing

Effectiveness of low sensitivity interventions in west Africa Ebola epidemic

Richard Williams, a student from Morehouse College, worked with Dr. John Drake to develop a model examining the effectiveness of low-sensitivity interventions in disease outbreaks. Abstract: We conducted a theoretical study to investigate the effect of low sensitivity interventions on the containment of an emerging pathogen. Low sensitivity interventions  such as thermal scans for febrile

Development of deterministic and stochastic models for a T7 phage-E. coli system with vaccination strategy implementation

Abigail Smith, from Carnegie Mellon University, worked with Reni Kaul in the lab of Dr. John Drake to develop models to study the effectiveness of vaccination strategies. Abigail L. Smith1, RajReni B. Kaul2 and John M. Drake2 1Carnegie Mellon University, 2Odum School of Ecology, University of Georgia Vaccination is widely considered the most effective method

Effects of pH and Temperature Variability on Fungal Pathogen Development and Population Survival in Daphnia

For this project, based in the lab of Dr. John Drake, Trianna Humphrey worked with Tad Dallas to study the effect of changing environmental conditions on a host-parasite relationship. Trianna Humphrey, Tougaloo College Tad Dallas, Odum School of Ecology, University of Georgia  Extreme environmental conditions can have an influence on host-parasite relationships and capable of

When ideas go viral: Early warning signals in theoretical and real-world social contagion systems

Lexi Lerner, a biology major from Brown University, worked with Dr. John Drake to look for critical slowing down in consumer fad systems. Abstract: Consumer fads are often characterized by unpredictable explosive outbreaks. Early warning signals have been retroactively successful at anticipating critical phenomena of complex systems such as infectious disease epidemics, but they have

Quantifying the Performance of Spatial and Temporal Early Warning Signals of Disease Elimination

Dominic Gray, a student from Norfolk State University, and Dr. John Drake from the Odum School of Ecology examined the use of temporal early warning signals in disease dynamics. Dominic Gray, Norfolk State University John Drake, Odum School of Ecology, University of Georgia Early warning signals of disease emergence and elimination seek to forecast changes

Using the power ratio as an early warning signal to detect critical transitions for disease emergence and eradication

Paige Miller, from Gustavus Adolphus College, and Dr. John Drake in the Odum School of Ecology, examined early warning signals in disease systems. Paige Miller, Gustavus Adolphus College John Drake, Odum School of Ecology, University of Georgia  Infectious diseases have ravaged the human population since the beginning of time. Eradication of human infectious diseases has
