MMWR Morb Mortal Wkly Rep. 2015 Feb 6;64(4):111.
During December 15, 2014-January 16, 2015, the U.S. Department of Agriculture received 14 reports of birds infected with Asian-origin, highly pathogenic avian influenza A (HPAI) (H5N2), (H5N8), and (H5N1) viruses. These reports represent the first reported infections with these viruses in U.S. wild or domestic birds. Although these viruses are not known to have caused disease in humans, their appearance in North America might increase the likelihood of human infection in the United States. Human infection with other avian influenza viruses, such as HPAI (H5N1) and (H5N6) viruses and (H7N9) virus, has been associated with severe, sometimes fatal, disease, usually following contact with poultry.
2014 年 12 月 15 日至 2015 年 1 月 16 日期间,美国农业部收到了 14 份报告,称鸟类感染了亚洲起源的高致病性禽流感病毒 A(HPAI)(H5N2)、(H5N8)和(H5N1)。这些报告代表了美国野生或家养鸟类首次报告感染这些病毒。尽管这些病毒目前还没有导致人类患病的记录,但它们在北美的出现可能会增加美国发生人类感染的可能性。人类感染其他禽流感病毒,如高致病性禽流感病毒(H5N1)和(H5N6)病毒以及(H7N9)病毒,通常与接触家禽有关,与严重甚至致命疾病相关。
