Background and Objectives: Infection of birds to Highly Pathogenic Avian Influenza (HPAI) and their extinction impose heavily losses on the livestock and poultry industry along with public health. Nowadays, due to the volume and variety of data, the need of using location-based technologies and data mining sciences has become inevitable. This study aims to model the prevalence of avian influenz...

Highly pathogenic avian influenza virus A/H5N1 has been reported in 11 African countries. Migratory waterbirds have the potential of introducing A/H5N1 into east Africa through the Rift Valley of Kenya. We present the results of a wild bird surveillance system for A/H5N1 and other avian influenza viruses based on avian fecal sampling in Kenya. We collected 2630 fecal samples in 2008. Viral RNA ...

background and objectives: a number of different subtypes of avian influenza (ai) viruses have emerged in humans includingh5n1, h7n2, h7n7 and h9n2. these influenza viruses are excreted in the infected birds and in their respiratory secretions.the aim of this study was to investigate seropositivity against h9n2 and h7n7 viruses among poultry and slaughterhouse workers with occupational risk of ...

UNLABELLED Zoonotic avian influenza virus infections may lead to epidemics or pandemics. The 1918 pandemic influenza virus has an avian influenza virus-like genome, and its H1 hemagglutinin was identified as a key mammalian virulence factor. A chimeric 1918 virus expressing a contemporary avian H1 hemagglutinin, however, displayed murine pathogenicity indistinguishable from that of the 1918 vir...

objectives the aim of this was to indentify the presence of a/h9n2 virus among different high risk occupational groups, in tehran and qazvin provinces in seasonal outbreak in iran. background in the last decade h9n2 avian influenza viruses had caused outbreaks in poultry in many parts of the world. this subtype could infect other animals such as human and pig. avian h9n2 virus has acquired rece...

A reassortant influenza A virus was produced by mating an avian influenza A/Pintail/Alberta/119/79 (H4N6) virus with wild-type human influenza A/Washington/897/80 (H3N2) virus. The avian-human influenza A reassortant virus contained the genes coding for the hemagglutinin and neuraminidase surface antigens of the human influenza wild-type virus and the six other RNA segments (internal genes) of ...

Avian influenza viruses may cause mild or severe disease in birds. There have been five recorded outbreaks of highly pathogenic avian influenza in birds in Australia, all of which were caused by the H7 subtype. These were quickly controlled and similar coordinated responses are expected for possible future outbreaks of avian influenza. Migratory birds are not regarded as the source of these out...

T ongoing avian influenza (H5N1) pandemic poses risks to both human and animal health (1–5). The potential exists for cross-species transmission of avian influenza to humans and subsequent reassortment of avian and human influenza viruses in coinfected persons (6). Although atypical presentations of avian influenza (H5N1) have been reported (7,8), in most H5N1 case-patients pneumonia was the pr...

H6N1 influenza A is an avian virus but in 2013 infected a human in Taiwan. We studied the phylogeography of avian origin H6N1 viruses in the Influenza Research Database and the Global Initiative on Sharing Avian Influenza Data EpiFlu Database in order to characterize their recent evolutionary spread. Our results suggest that the H6N1 virus that infected a human in Taiwan is derived from a diver...
