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

In January 2021, Senegal detected the spread of Eurasian highly pathogenic avian influenza A(H5N1) to its territory, marking a significant intercontinental jump from Europe. The virus was identified on a poultry farm in Thies and in great white pelicans within the Djoudj National Bird Sanctuary. This study provides evidence for the transcontinental movement of H5N1, highlighting the role of migratory birds in viral dissemination across continents. Researchers analyzed samples to trace the virus's origin and spread, emphasizing the need for enhanced surveillance and control measures at World Heritage Sites like Djoudj to mitigate risks associated with avian influenza.
