Live Poultry Market Closure and Control of Avian Influenza A(H7N9), Shanghai, China

To the Editor: China reported its first human infections with avian influenza A(H7N9) virus in late March 2013 (1). In the following weeks, 131 human infections were confirmed; 33 occurred in Shanghai (http://www. moh.gov.cn). Because infection with this novel virus had a high fatality rate and posed a pandemic risk, Shanghai disease control authorities launched rapid investigations to identify...

Effect of Live Poultry Market Interventions on Influenza A(H7N9) Virus, Guangdong, China

Since March 2013, three waves of human infection with avian influenza A(H7N9) virus have been detected in China. To investigate virus transmission within and across epidemic waves, we used surveillance data and whole-genome analysis of viruses sampled in Guangdong during 2013-2015. We observed a geographic shift of human A(H7N9) infections from the second to the third waves. Live poultry market...

Genome Sequence of a Novel H10N9 Avian Influenza Virus Isolated from Chickens in a Live Poultry Market in Eastern China

An H10N9 avian influenza virus (AIV) strain, A/Chicken/Jiangsu/RD5/2013, was isolated in China. The hemagglutinin (HA) and neuraminidase (NA) genes in this strain originated from H10N1 and H7N9 AIVs, respectively, and the other genes derived from H7N3 AIVs. Sequence analysis implies that the H10N9 AIV may be an NA gene donor for the human H7N9 influenza viruses.

H7N9 and H5N1 avian influenza suitability models for China: accounting for new poultry and live-poultry markets distribution data

In the last two decades, two important avian influenza viruses infecting humans emerged in China, the highly pathogenic avian influenza (HPAI) H5N1 virus in the late nineties, and the low pathogenic avian influenza (LPAI) H7N9 virus in 2013. China is home to the largest population of chickens (4.83 billion) and ducks (0.694 billion), representing, respectively 23.1 and 58.6% of the 2013 world s...
