RESTON, Va. — Waterfowl in California can spread low pathogenic avian influenza viruses during summertime when wetland temperatures are warm and waterfowl densities are low, according to a recent U.S. Geological Survey study.
Scientists from the USGS National Wildlife Health Center, the Wisconsin Cooperative Wildlife Research Unit, the USGS Western Ecological Research Center and the University of Wisconsin-Madison found that, rather than persisting primarily in colder northern wetlands as previously thought, low pathogenic avian influenza viruses can be carried within low-density waterfowl populations in high water temperatures. These findings indicate a previously unknown reservoir for low pathogenic avian. . .
