Avian Influenza (H7N9) Viruses Co-circulating among Chickens, Southern China
نویسندگان
چکیده
In April 2017, three avian influenza (H7N9) viruses were isolated from chickens in southern China. Each virus had different insertion points in the cleavage site of the hemagglutinin protein compared to the first identified H7N9 virus. We determined that these viruses were double or triple reassortant viruses.

Infection with Possible Precursor of Avian Influenza A(H7N9) Virus in a Child, China, 2013
During the early stage of the avian influenza A(H7N9) epidemic in China in March 2013, a strain of the virus was identified in a 4-year-old boy with mild influenza symptoms. Phylogenetic analysis indicated that this strain, which has similarity to avian subtype H9N2 viruses, may represent a precursor of more-evolved H7N9 subtypes co-circulating among humans.

BACKGROUND In 2013, a novel H7N9 avian influenza virus (AIV) was isolated from ill humans in Shanghai and Anhui Province, China. Since then, the virus has spread quickly throughout China. Previous isolation of H7N2 virus from swine suggests that additional H7 subtype AIVs may be transmitted through pigs. However, prior to the recent zoonosis of H7N9, there were very few studies on the seropreva...

BACKGROUND On March 30, 2013, a novel avian influenza A H7N9 virus that infects human beings was identified. This virus had been detected in six provinces and municipal cities in China as of April 18, 2013. We correlated genomic sequences from avian influenza viruses with ecological information and did phylogenetic and coalescent analyses to extrapolate the potential origins of the virus and po...
متن کاملCirculation of Reassortant Influenza A(H7N9) Viruses in Poultry and Humans, Guangdong Province, China, 2013
Influenza A(H7N9) virus emerged in eastern China in February 2013 and continues to circulate in this region, but its ecology is poorly understood. In April 2013, the Guangdong Provincial Center for Disease Control and Prevention (CDC) implemented environmental and human syndromic surveillance for the virus. Environmental samples from poultry markets in 21 city CDCs (n=8,942) and respiratory sam...
متن کاملGenome 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.
