Avian Flu



The goal of our research is to use epidemiological modeling to better understand the dynamics of low-pathogneic avian influenza virus (LPAIv) in waterfowl populations.  By combining laboratory and field data on infection, prevalence, and shedding patterns of AIv, we have been able to determine the rate of disease transmssion in wild poplations and how these factors might affect potential outbreaks of highly-pathogenic avian influenza (HPAIv).  Our results show that better understanding of AIv transmission requires information on both current infection and previosu serological exposure of wild birds.
