Estimating Movement Rates Between Eurasian and North American Birds That Are Vectors of Avian Influenza
Avian influenza (AI) is a zoonotic disease that will likely be involved in future pandemics. Because waterbird movements are difficult to quantify, determining the host-specific risk of Eurasian-origin AI movements into North America is challenging. We estimated relative rates of movements, based on...

Avian influenza (AI) is a zoonotic disease that will likely be involved in future pandemics.
