SUMMARYWest Nile virus (WNV) is a zoonotic arthropod-borne pathogen with continued geographical expansion in Europe. We present and evaluate data on the temporal, spatial and bird species focus of the WNV surveillance programme in dead wild birds in Great Britain (2002–2009). During this period all bird samples tested negative for WNV. Eighty-two per cent of the 2072 submissions occurred during the peak period of vector activity with 53% tested during April–July before human and equine infection would be expected. Samples were received from every county, but there was significant geographical clustering (nearest neighbour index=0·23, P<0·001). Over 240 species were represented, with surveillance more likely to detect WNV in resident bird species (92% of submissions) than migrants (8%). Evidence indicates that widespread avian mortality is not generally a reported feature of WNV in Europe and hence additional activities other than dead bird surveillance may maximize the ability to detect WNV circulation before the onset of human and equine infections.

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.

H5n1 Hpai

SUMMARYHighly pathogenic avian influenza (HPAI) subtype H5N1 remains a public health threat as long as it circulates in wild and domestic birds. Information on the transmissibility of H5N1 HPAI from wild birds is needed for evidence-based public health advice. We investigated if transmission of H5N1 HPAI had taken place in people that had unprotected contact with infected wild mute swans during an incident at the Abbotsbury Swannery in Dorset, England. Thirteen people who had been exposed to infected swans were contacted and actively followed up for symptoms. Serology was taken after 30 days. We did not find evidence of transmission of H5N1 HPAI to humans during the incident. The incident provided a rare opportunity to study the transmissibility of the virus from wild birds to humans.
