        GLOBAL - The United States, Canada and some European Union countries took part in an on-line conference on PEDv last week, organized by the England Pig Health and Welfare Council.The United States reported continued outbreaks of PEDv, including secondary breakdowns, but no reported third breakdowns, and no spike in outbreaks so far this winter, reports the UK's National Pig Association (NPA).

      This is borne out by another on-line update last week, organised by the National Pork Board, when several experts said the recently announced year-on-year two per cent increase in the national pig inventory may reflect a sow herd that has gained some immunity from PEDv. There are still no reports of Asian-American PEDv spreading from the Ukraine to any European Union countries but low-pathogenic PED has been reported in Germany, the Netherlands and France, and there may have been some cases in Spain too, although this has not been confirmed.    

      全球——上周美国、加拿大和一些欧盟国家参加PEDv在线研讨会,这次会议由英国猪的健康和福利委员会组织。美国报道了PEDv的持续爆发,包括第二期的衰退,但没有公布第三期的衰退,今年冬天还没有出现PEDv病例激增的情况,英国全国养猪协会(NPA)报告。

      上周由国家猪肉委员会组织的另一个在线更新信息证实,一些专家表示,最近公布的全国猪库存同比增长2%,可能反映出母猪获得了一些PEDv豁免权。还有没有亚州-美洲PEDv从乌克兰传播到任何欧盟国家的报道,但据报道低致病性PEDv在德国、荷兰和法国出现,西班牙可能有一些病例,虽然这些信息尚未得到证实。
