H5n1 Hpai

We conducted active surveillance for avian influenza virus using sentinel ducks in central region of Mongolia (Khunt lake Saikhan soum, Bulgan province) that major wild bird habitat and outbreak site of H5N1 HPAI in wild birds in Mongolia from 2005 to 2011. Total of 39/104 (37,5%) samples were positive by insulated isothermal PCR (iiPCR) and 42/104 (40,38%) swab samples were positive by real time PCR (qPCR). In addition, AIV antibody detected in 35/104 (33,65%) serum samples tested by AIV NP ELISA kit. These results indicated that sentinel surveillance using domestic birds could be an effective method for avian pathogens including influenza in Mongolia. Enhanced sentinel surveillance in wild bird populations in Mongolia is therefore crucial for the understanding of global AIV transmission and epidemiology. Шувууны томуугийн тандах судалгаанд туршуул шувуу (Sentinel bird) байршуулах арга ашигласан дүнгээс Бид шувууны томуугийн тандах судалгаанд туршуул шувуу байршуулах арга зүйг ашиглах боломжийг судлах зорилгоор урьдчилсан туршилтыг 2019 оны 7-10 сард Булган аймгийн Сайхан сумын Хунт нууранд хийж гүйцэтгэв. Хунт нуур нь олон тооны нүүдлийн усны шувууд зусах болон дайрч өнгөрдөг ач холбогдолтой цэг бөгөөд 2005-2011 онд өндөр хоруу чанартай шувууны томуугийн (HPAI) A/H5N1 дэд хэвшлийн вирус илэрч байсан. Шувуунаас авсан арчдасны зарим дээжийг insulated isothermal PCR (iiPCR)-р шинжлэхэд 39/104 (37,5%), дээж эерэг, бүх дээжийг PCR (qPCR)-р шинжлэхэд 42/104 (40,38%) нь дээж эерэг дүн үзүүлсэн. Харин ийлдсэнд шувууны томуугийн эсрэг бием илрүүлэх ELISA-ийн шинжилгээгээр  35/104 (33,65%) дээжинд  эсрэг бием илэрсэн. Иймд энэ арга зүйг Монгол орны нөхцөлд тохируулан сайжруулж шувууны томуугийн үүсгэгчийг илрүүлэхэд ашиглах нь уг өвчний эпидемиологийн байдлыг танин мэдэхэд чухал ач холбогдолтой  юм.

AbstractThis paper takes a closer look at three interrelated areas of study: avian host biology, the role of human activities in virus transmission, and the surveillance activities centered on avian influenza in wild birds. There are few ecosystems in which birds are not found. Correspondingly, avian influenza viruses are equally global in distribution, relying on competent avian hosts. The immune systems, annual cycles, feeding behaviors, and migration patterns of these hosts influence the ecology of the disease. Decreased biodiversity has also been linked to heightened disease transmission in several disease systems, and it is evident that active destruction and modification of wetland environments for human use is impacting avian populations drastically. Legal and illegal trade in wild birds present a significant risk for introduction and maintenance of exotic diseases. After the emergence of HPAI H5N1 in Hong Kong in 1996 and the ensuing geographic spread of outbreaks after 2003, both infected countries and those at risk of introduction began intensifying avian influenza surveillance efforts. Several techniques for sampling wild birds for influenza viruses have been applied. Benefits, problems, and biases exist for each method. The wild bird avian influenza surveillance programs taking place across the continents are now scaling back due to the rise of other spending priorities; hopefully the lessons learned from this work will be preserved and will inform future research and disease outbreak response priorities.

Wild aquatic birds are the natural reservoir for avian influenza viruses (AIVs)1. Increased surveillance has revealed that Australia has its own lineages of these AIVs.

Abstract Background Several outbreaks of highly pathogenic avian influenza (HPAI) caused by influenza A virus of subtype H5N8 have been reported in wild birds and poultry in Europe during autumn 2020. Norway is one of the few countries in Europe that had not previously detected HPAI virus, despite widespread active monitoring of both domestic and wild birds since 2005. Results We report detection of HPAI virus subtype H5N8 in a wild pink-footed goose (Anser brachyrhynchus), and several other geese, ducks and a gull, from south-western Norway in November and December 2020. Despite previous reports of low pathogenic avian influenza (LPAI), this constitutes the first detections of HPAI in Norway. Conclusions The mode of introduction is unclear, but a northward migration of infected geese or gulls from Denmark or the Netherlands during the autumn of 2020 is currently our main hypothesis for the introduction of HPAI to Norway. The presence of HPAI in wild birds constitutes a new, and ongoing, threat to the Norwegian poultry industry, and compliance with the improved biosecurity measures on poultry farms should therefore be ensured. [MK1]Finally, although HPAI of subtype H5N8 has been reported to have very low zoonotic potential, this is a reminder that HPAI with greater zoonotic potential in wild birds may pose a threat in the future. [MK1]Updated with a sentence emphasizing the risk HPAI pose to poultry farms, both in the Abstract and in the Conclusion-section in main text, as suggested by Reviewer 1 (#7).
