Persistence of low pathogenic avian influenza virus in waterfowl in a Southern African ecosystem

Ecohealth. 2011 Mar;8(1):109-15. doi: 10.1007/s10393-010-0356-4. Epub 2010 Dec 2.

Abstract

Waterfowl were counted and sampled in a Zimbabwean wetland over 24 months. LPAI strains were detected during 20 consecutive months, providing evidence of regional yearly persistence of LPAI. We discuss the role of Afro-tropical ducks in viral maintenance and transmission, and attempt to explain the observed patterns.
