Intercontinental Spread of Eurasian Highly Pathogenic Avian Influenza A(H5N1) to Senegal

Fatou T Lo et al. Emerg Infect Dis. 2022 Jan.

Abstract

In January 2021, Senegal reported the emergence of highly pathogenic avian influenza virus A(H5N1), which was detected on a poultry farm in Thies, Senegal, and in great white pelicans in the Djoudj National Bird Sanctuary. We report evidence of new transcontinental spread of H5N1 from Europe toward Africa.

Keywords: HPAI H5N1 virus; Senegal; influenza; poultry; transcontinental spread; viruses; white pelicans; zoonoses.

Origin and spread of the highly pathogenic avian influena H5N1 virus. Five discrete geographic regions, namely Central Asia, Northern Europe, Eastern Europe, Southern Europe, and Senegal, are defined and marked with different colors. The routes of migration supported by a Bayes factor >10 are displayed in the map as thin dashed lines; thicker dashed lines indicate Bayes factor >20.
