Genetic Characterization of Continually Evolving Highly Pathogenic H5N6 Influenza Viruses in China, 2012–2016
H5N6 is a highly pathogenic avian influenza (HPAI) and a zoonotic disease that causes recurring endemics in East Asia. At least 155 H5N6 outbreaks, including 15 human infections, have been reported in China. These repeated outbreaks have increased concern that the H5N6 virus may cross over to humans and cause a pandemic. In February, 2016, peafowls in a breeding farm exhibited a highly contagio...
متن کاملContinuing Reassortant of H5N6 Subtype Highly Pathogenic Avian Influenza Virus in Guangdong
First identified in May 2014 in China's Sichuan Province, initial cases of H5N6 avian influenza virus (AIV) infection in humans raised great concerns about the virus's prevalence, origin, and development. To evaluate both AIV contamination in live poultry markets (LPMs) and the risk of AIV infection in humans, we have conducted surveillance of LPMs in Guangdong Province since 2013 as part of en...
متن کاملCharacterization of Highly Pathogenic Avian Influenza Virus A(H5N6), Japan, November 2016
Highly pathogenic avian influenza viruses (HPAIVs) A(H5N6) were concurrently introduced into several distant regions of Japan in November 2016. These viruses were classified into the genetic clade 2.3.4.4c and were genetically closely related to H5N6 HPAIVs recently isolated in South Korea and China. In addition, these HPAIVs showed further antigenic drift.
متن کاملNew Reassortant H5N6 Highly Pathogenic Avian Influenza Viruses in Southern China, 2014
New reassortant H5N6 highly pathogenic avian influenza viruses (AIVs) were isolated from apparently healthy domestic ducks in Southern China in 2014. Our results show that the viruses grew efficiently in eggs and replicated systemically in chickens. They were completely lethal in chicken (100% mortality), and the mean death time was 6 to 7 days post-inoculation. The viruses could transmit in ch...
متن کاملAvian influenza A(H5N6): the latest addition to emerging zoonotic avian influenza threats in East and Southeast Asia
Context of new emerging subtypes of Avian Influenza viruses in eastern Asia The first reported appearance of a global zoonotic influenza of avian origin dates from 1996, when an outbreak of H5N1 highly pathogenic avian influenza (HPAI) occurred on a goose farm in Guangdong Province, China [Guan et Smith, 2013]. One year later, the H5N1 HPAI virus was recognised as a zoonotic agent with 18 human...
