Evolution of Highly Pathogenic Avian Influenza A(H5N1) Virus in Poultry, Togo, 2018.

In 2015, highly pathogenic avian influenza A(H5N1) viruses reemerged in poultry in West Africa. We describe the introduction of a reassortant clade 2.3.

Surveillance for influenza viruses in poultry and swine, west Africa, 2006-2008.

To determine the extent of animal influenza virus circulation in Côte d'Ivoire, Benin, and Togo, we initiated systematic year-round active influenza surveillance in backyard birds (predominantly chickens, guinea fowl, and ducks) and pigs. A total of 26,746 swab specimens were screened by using reverse transcription PCR. Animal influenza prevalence was estimated at 0 (95% CIs for each of the 2 study years 0-0.
