Abstract
Recently, the emergence of a novel reassortant H7N2 avian influenza virus (AIV) was reported in this journal, and the genetic characteristics suggested this novel H7N2 AIV was a reassortant virus of H7N9 and H9N2 AIVs that are circulating in China. 1 Qiu Y. Sun R. Hou G. Yu X. Li Y. Li J. et al. Novel reassortant H7N2 originating from the H7N9 highly pathogenic avian influenza viruses in China. J Infect. 2019; 79 (PubMed PMID: 31473272.

Cui S. Sun Y. Zhang X. Ma C. Shi W. et al. Human infection with H9N2 avian influenza in northern China. Clin Microbiol Infect. 2018; 24 (PubMed PMID: 29104171.

Meanwhile, the H9N2 AIV continued to act as genetic donor to multiple novel AIVs, including H7N9, H10N8, H6N1, H6N2, and H5N1. 3 Liu D. Shi W. Gao G.F Poultry carrying H9N2 act as incubators for novel human avian influenza viruses. Lancet. 2014; 383 (PubMed PMID: 24581684.

In this study, we report a novel genotype ressortant H9N2 strain, A/chicken/Baise/0701/2019(H9N2) (BS/2019), isolated from an acutely ill chicken farm in Baise city, China during the routine surveillance.
