The author beriefly describes current situation about H7N9 and source of the virus.
1'54
There if no evidence of human-to-human transmission.
There is some good news to be gleaned from using online data sources for disease surveillance: the absence of an increase in flu-related searches before the H7N9 news broke indicates that there has not been an undetected surge in cases prior to the official announcement.
1'56
nCoV has raised concern.
The new serologic tests will help to identify more infected people, regardless of whether the symptoms are mild or severe.
While human-to-human transmission has occurred, it seems as though this is not an efficient method of transmission for the virus.
1'16
A wider distribution of testing will help ensure the broadest surveillance network to determine the true extent and severity of this novel illness.
While the threat of an epidemic is still present, these new advances will help public health officials be more prepared.
1'32
bNAbs are unlike regular antibodies because they can continually fight HIV even as it mutates.
Only about twenty percent of people produce this type of antibody as a response to infection with HIV.
If scientists can understand what triggers the production of these powerful antibodies, they could theoretically create a vaccine that could also initiate production of bNAbs.

MI：We are rapidly learning a lot about both of these viruses.There is no specific treatment, either, but the WHO states that H7N9 is susceptible (vulnerable) to certain drugs such as oseltamivir and zanamivir.
Structure:
>>>There is one key fact that remains unknown: what is transmitting this virus to humans? What is the reservoir for this virus?

1) The good news is that this virus is not well adapted to humans, so human to human transmission is rare, at least for the moment.Clearly, we will have to continue careful monitoring of the spread of H7N9.
   
   So why is it called ‘avian influenza’ or ‘swine flu,’ yet, people get sick?
   when the new influenza virus – that which has been produced inside the human host cell – is ready to bust out and infect other cells, it can be a combination of segments from two different influenza viruses.

2)The likelihood a host will be infected with two different influenza viruses depends on the host and the influenza viruses circulating.

>>>There is currently no vaccine for H7N9, but experts are debating the development of one.
There is no specific treatment, either, but the WHO states that H7N9 is susceptible (vulnerable) to certain drugs such as oseltamivir and zanamivir.

发现我总是在似曾相识的生词面前纠结。
越障回想了一下结构，然后重看了一遍，才发现自己理解有误。。。。。。

开头背景介绍：最近有H5N9和冠装病毒
提问方式来引出后文两大内容：病毒哪里来的；病毒怎么传染给人类的
后文分别叙述：先回顾HN系列各种分支，按时间顺序回顾爆发，然后生物学上如何传播给人类；是否研发疫苗

1.2'29 the H7N9 virus spread in China. and this brand new H7N7 is mainly from birrds and chicken. how can we protect ourself from this?
2.the H7N9 will not become a widespread disease. and some effective vaccine will not be used untill we found that H7N9 can be spreaded between human. Research on Baidu engine suggest that no commen flu cases exist before the official annoucement.
3.2'39 many methods have been developed to detect this kind of disease.
4.3'00 animal models are used in the research. the scientist are trying their best to know more about this noval disease.
5.2'25 scientist found that a kind of antibody calld bRNAbs can fight with HIVs even when HIV keep mutating in body. They are trying to find out what trigger the body to generat bNAbs.
5.5 rest 2'25 it is very difficult to develope effective vaccine for AIDS because HIV is good at hiding from immune system and mutating frequently. But the research on bANbs is very promising.
Obstacle:8'20

Firstly, H7N9 is attracting the attention of public. Government and scientists are taking actions in response to this new disease.2. there are many kind of virus in animals. how can they transfer to people? pigs play important roles. Finally..the whole society should try all means to debeat the disease....headache...don't want to read///
