H1N1?!

Influenza A virus subtype H1N1, also known as A(H1N1), is a subtype of influenzavirus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans and cause a small fraction of all influenza-like illness and a large fraction of all seasonal influenza. H1N1 strains caused roughly half of all human flu infections in 2006. Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza).

In June 2009, WHO declared that flu due to a new strain of swine-origin H1N1 was responsible for the 2009 flu pandemic. This strain is commonly called "swine flu".
In the 2009 flu pandemic, the virus isolated from patients in the United States was found to be made up of genetic elements from four different flu viruses – North American Mexican influenza, North American avian influenza, human influenza, and swine influenza virus typically found in Asia and Europe – "an unusually mongrelised mix of genetic sequences. This new strain appears to be a result of reassortment of human influenza and swine influenza viruses, in all four different strains of subtype H1N1.

Preliminary genetic characterization found that the hemagglutinin (HA) gene was similar to that of swine flu viruses present in U.S. pigs since 1999, but the neuraminidase (NA) and matrix protein (M) genes resembled versions present in European swine flu isolates. The six genes from American swine flu are themselves mixtures of swine flu, bird flu, and human flu viruses. While viruses with this genetic makeup had not previously been found to be circulating in humans or pigs, there is no formal national surveillance system to determine what viruses are circulating in pigs in the U.S.

On June 11, 2009, the WHO declared an H1N1 pandemic, moving the alert level to phase 6, marking the first global pandemic since 1968.










早上还在睡的时候，电话响一看原来是她，
叫我早起等下又迟到咯~~ 开心^^
就去冲凉咯，怎知身体还没适应淋了冷水，
结果=打喷嚏，伤风了~~XD
到学校礼堂集合，老师报告说有三个学生被隔离了，
说是患了最近流行的H1N1噢，
刚好我鼻塞，就被朋友说我也患了。=.=''
也因为酱，可以吓人了~~哈哈哈…
看到她，她好像很闷闷，不知道为什么，也没特意去问。
不过，她朋友也说她没什么讲话~



最讨厌是被老师抓来骂，我们去做东西，
却说我们逃课，还把我们臭骂。
好在过后没事，有个朋友却因为老师说他无礼，
扣了十分……

有上课的日子，大概都是将普通吧，
重重复复，重复又重复~
放学偷偷尾随她，然后看到两个男子去和他说话，
之前有邀她去拍外景的，不怎么想她去，
因为……不用说也知吧？
妈妈也很紧张我和弟弟，一听到说学校有人患H1N1，
就立刻打给我叫我不要呆在学校太久，
好幸福哦~~嘻嘻嘻嘻……

回到家，又冲了凉，就问她看她有答应去没，
她有去~~也有问我要跟没。
我要我要我要！
耶耶耶，可以跟她去了！

是时侯睡午觉了~~~~~~~~~~
睡个甜甜的午觉~~^^
