在中国发生人感染流感病毒 H7N9 的常见问题解答 5-7
过去全球发生人感染 H7 流感病毒的情况如何？
From 1996 to 2012, human infections with H7 influenza viruses (H7N2, H7N3, and H7N7) were reported in the Netherlands, Italy, Canada, United States of America, Mexico and the United Kingdom. Most of these infections occurred in association with poultry outbreaks. The infections mainly resulted in conjunctivitis and mild upper respiratory symptoms, with the exception of one death, which occurred in the Netherlands. Until now, no human infections with H7 influenza viruses have been reported in China.
1996 年到 2012 年，荷兰、意大利、加拿大、美国、墨西哥和英国均有人感染 H7 流感病毒 (H7N2, H7N3, 和 H7N7) 的报道，其中大部分感染发生在养禽场，主要症状是结膜炎和轻度的上呼吸系统症状，仅在荷兰发生一个死亡病例。至今为止，中国没有发现人感染 H7 流感病毒。
6. Is the influenza A(H7N9) virus different from influenza A(H1N1) and A(H5N1) viruses?
H7N9 和 H1N1 以及 H5N1 的区别？
Yes. All three viruses are influenza A viruses but they are distinct from each other. H7N9 and H5N1 are considered animal influenza viruses that sometimes infect people. H1N1 viruses can be divided into those that normally infect people and those that normally infect animals.
这三个都是甲型流感病毒且互不相同。 H7N9 和 H5N1 主要感染动物，偶见人流感。H1N1 分两种，一种通常感染人，一种通常感染动物。
7. How did people become infected with the influenza A(H7N9) virus?
人是怎么感染 H7N9 病毒的？
Some of the confirmed cases had contact with animals or with an animal environment. The virus has been found in a pigeon in a market in Shanghai. It is not yet known how persons became infected. The possibility of animal-to-human transmission is being investigated, as is the possibility of person-to-person transmission.
部分确诊病人曾与动物接触或处于动物环境中。上海某市场的一只鸽子身上发现该病毒，人被感染的途径目前不明。现在正在调查动物到人以及人到人的转播可能。
