We have surveyed avian influenza virus (AIV) genomes from live poultry markets within
China since 2014. Here we present a total of 16,091 samples that were collected from May
2016 to February 2019 in 23 provinces and municipalities in China. We identify 2048 AIV-
positive samples and perform next generation sequencing. AIV-positive rates (12.73%) from
samples had decreased substantially since 2016, compared to that during 2014–2016
(26.90%). Additionally, H9N2 has replaced H5N6 and H7N9 as the dominant AIV subtype in …
