All cases were the workers who had been involved in culling birds, catching the bird flu virus through direct work with infected birds.Human symptoms among all infected workers were relatively mild, such as conjunctivitis and eye tearing, as well as some typical of a flu infection.
所有案例都是曾經參與撲殺禽類的工人，他們經由與受感染禽類的直接接觸，而感染禽流感病毒。所有受感染工人的症狀只有輕微的程度，像是結膜炎和眼睛流淚，以及一些典型的流感感染症狀。
Testing also showed that the virus was closely related to the strain spreading in cattle, raising concerns about a growing number of infections.
測試還顯示，這種病毒與在牛群中擴散的菌株密切相關，這引發對感染病例增長的擔憂。
CDC’s current assessment is that the risk to the public from H5N1 remains low and there have been no documented instances of human-to-human transmission.
目前CDC的評估認為，H5N1對公眾的風險仍然較低，且尚未有記錄有人傳人的案例。
