Continuing evolution of H6N2 influenza A virus in South African chickens and the implications for diagnosis and control [post]

2019 unpublished
The threat of poultry-origin H6 avian influenza viruses to human health emphasizes the importance of monitoring their evolution. South Africa's H6N2 epidemic in chickens began in 2001 and two co-circulating antigenic sub-lineages of H6N2 could be distinguished from the outset.
