Caron A., Abolnik C., Mundava J., Gaidet N., Burger C.E., Mochotlhoane B., Bruinzeel L.W., Chiweshe N., De Garine-Wichatitsky M., Cumming G.S.. 2011. Ecohealth, 8 (1) : p. 109-115. International One Health Congress. 1, 2011-02-14/2011-02-16, Victoria (Australie).

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. (Résumé d'auteur)
