[TD]Risk-based surveillance of H7N9 in targeted border Townships and live bird market in Yangon and Mandalay has been conducted since 2013 by cooperation between the Livestock Breeding and Veterinary Department and FAO. Until now, the 5th round of the risk based surveillance of H7N9 has been conducted and 16545 chickens and ducks oropharyngeal swabs, 7765 environmental swabs and 705 duck sera were collected from poultry collecting points, poultry processing sites, formal city markets and live bird markets. Those samples were tested in Mandalay and Yangon Diagnostic Laboratory and then confirmed and sequenced by the Australian Animal Health Laboratory, Geelong. From this 5th round of active surveillance, clade 2.3.4.4 H5N6 HPAI virus, which shares 99% similarity with A/chicken/Hubei/XG18/2015(H5N6) and 98% similarity with A/duck/Guangdong/GD01/2014(H5N6), was detected in the samples collected from chicken and environmental swabs in Monglar, which has a common border with China. H5N6 positive samples were taken from apparently healthy chickens imported from China, as well as from the environment. H5N6 positive samples were more concentrated geographically and temporally, and were found specifically in live bird markets, in ducks and chickens imported from China (unknown breeds).[/TD]
