Abstract
We detected West Nile virus (WNV) nucleic acid in crocodiles (Crocodylus niloticus) in Zambia. Phylogenetically, the virus belonged to lineage 1a, which is predominant in the Northern Hemisphere. These data provide evidence that WNV is circulating in crocodiles in Africa and increases the risk for animal and human transmission.

West Nile virus (WNV) was detected in snakes (2), and antibodies against WNV were found in farmed crocodiles (Crocodylus niloticus) in Israel and Mexico and in alligators (Alligator mississippiensis) in the United States (3)
Phylogenetic analysis of the complete polyprotein amino acid sequence of Croc110/2019/ZM grouped the virus in lineage 1a
