据中国之声《央广新闻》报道，由我国和世界卫生组织组成的人感染H7N9禽流感防控联合考察组，今天（24日）上午卫生计生委召开通报会，通报本周考察的情况。

According to the voice of China[Epicenter wide news]reports,Made up of our country and the world health organization of human infection with H7N9 joint bird flu prevention and control teams,today(24,)Morning briefings held health and family planning commission,Situation of inspection this week.

　　记者在通报会上了解到，考察组在19-23日在北京和上海进行了考察，考察组成员包括世界和我国流行病学、病毒学及临床管理和公共卫生方面的专家，考察的目的是评估H7N9的形式并且提出建议。经过考察，专家组认为，迄今为止我国采取的一些措施，如关闭上海活禽市场，是及时合理的，从上海的情况来看，迄今为止禽类传染仅仅限于活禽市场。

The reporter understands in the briefing,B in Beijing and Shanghai on 19-23 was investigated,Team members include the world and epidemiology in China/Virological and clinical management and public health experts,H7N9 expedition is the purpose of evaluation form, and put forward the proposal.After investigation,Expert group thinks,Some measures taken so far in our country,Such as shut down live-bird markets in Shanghai,Are reasonable in time,Judging from Shanghai,Poultry infected so far limited to live poultry markets.

　　但考察组提醒，专家对疾病严重程度的理解仍然有限，有些情况特别让人关切。如病毒看起来不会引起禽类出现明显病症，但由于人对于H7N9禽流感病毒没有抵抗力，所以在人群上的症状非常严重，这就使得它的跟踪和控制实践比较困难。而且现在几乎所有的病例都是散发出现，但也出现了几起家庭聚集性病例，但专家也不能确定这些聚集病例是由于家庭成员都接触了病毒来源，还是病毒出现了有限的人传人。迄今为止的证据还不足以得出存在人际间传播的结论，也还没有发现持续的人传人病例。

But b remind,Expert understanding of disease severity remains limited,In some cases special concern.If virus won't seem to cause birds appear obvious symptoms,But due to people for H7N9 avian flu virus without any resistance,So in the crowd of symptom is very serious,This makes it to track and control practices are difficult.And now almost all of the cases have been send out,But there have been several families gather cases,But experts are not sure these cases are due to family members contact the source of the virus,Or virus appeared limited human-to-human transmission.So far the evidence is not enough to come to the conclusion that there is interpersonal communication,Also found no sustained human-to-human transmission cases.

　　现在已经出现的100多例散发病例，大部分症状都比较严重，有20多人死亡，但现在不清楚有多少人携带病毒，但没有表现出任何症状，如北京的一位病毒携带者，病毒能不能获得人际间的传播能力还不是很清楚，所以不能完全排除有可能发展为人传人的可能。（记者李欣）

Now has more than 100 cases of sporadic cases,Most symptoms are severe,More than 20 people were killed,But now I don't know how many people carry the virus,But did not show any symptoms,As a carrier of Beijing,The spread of viruses can gain interpersonal ability is not very clear,So can't completely rule out the possibility of descendants may develop a.(The reporter li xin)
