Improving Early Detection and Prevention of Yellow fever
Yellow fever ecological transmission cycles in Africa
Multiple recent yellow fever outbreaks in Africa and South America have caused concern for further epidemics. Additionally, delayed detection of yellow fever may cause increased morbidity and mortality. We are working with public health officials in Ghana to develop risk maps and predictive models to help improve early outbreak detection.

Predicting Local West Nile Risk
West Nile virus causes the greatest morbidity and mortality of any arbovirus in North America. We are working with local public health officials and clinicians in California and Maryland to develop tools to predict which patients and communities are at greatest for neuroinvasive disease.
