The death of a woman in northern Alberta is the first confirmed death in Canada associated with swine flu, Alberta health officials said Friday.

"We have our first fatality in Alberta that's associated with the H1N1 flu," Alberta's chief medical officer of health, Dr. André Corriveau said. "I would like to begin by offering my sincerest condolences to the family of a northern Alberta woman who passed away recently."

The woman had chronic pre-existing health problems and had not travelled to Mexico. She died on April 28. It is not clear what role, if any, the virus played in her death and that might never be clear, Corriveau said.

The cause of death at the time was linked to her existing medical condition, but she was tested for swine flu after another family member from the same community contracted a mild form of the illness. The confirmation came back from the provincial lab on Thursday afternoon, Corriveau said.

Earlier reports indicated an elderly woman had died, but Corriveau said the woman was in her 30s. He would not say what community the woman was from.

The relative who was sick lived in the same house as the woman who died. It is not clear who was ill first but there are indications the woman may have been sick first.

A pathologist will take a closer look at the woman's lung tissue but that report won't be available until next week, said Dr. Gerry Predy, the senior medical officer of health for Alberta Health Services. The province will not release what underlying medical condition the woman had.
About 300 people attended the woman's funeral, which took place in what Predy described as a remote community.

"At the funeral there was a lot of activity where there could have been exchange of respiratory secretions, people hugging, kissing," he said.
Nurses have been sent to assess people in the community. Anyone with symptoms who has an underlying medical condition that could be complicated by swine flu will be treated with Tamiflu, Predy said.

Alberta also announced an additional eight confirmed cases of swine flu on Friday, bringing the provincial total to 42.

艾伯塔省首席卫生官安德烈·科里弗8日说,这是加首例与甲型H1N1流感相关的死亡病例,不过,死者生前还患有其他病症。

  如何防疫:凡出现猪流感疫情的国家和地区不要去;与猪流感病毒传染疑似的人不要接触;尽量避免逗留人流稠密,通风条件差的场所;注意个人卫生,必须勤洗手。出现流感症状,特别是来势汹汹的流感症状,一定要马上就医。  
  

   上海市第六人民医院呼吸机管理中心主任孙策在接受早报记者采访时也透露,调查显示,猪流感的死亡率在2.5%~5%之间。与以往SARS和禽流感相比, 此次因病死亡的人中大多为29-50岁的青壮年人,产生这一现象的原因可能与免疫力过强有关。他解释,当病毒侵入人体时,人体自身免疫力就将与其抗争。在 抗争中,当人体的免疫力过强时,有些病毒也会“遇强则强”,以至最终人体抵抗不了。

  呼吸病专家、中国工程院院士钟南山日前接受媒体专访时也表达了类似观点。 

   出现在墨西哥的疫情猪流感,其病毒为何如此凶悍?猪流感可以通过猪传染给人,目前的现象是人际传播,由人传染给人。有人问会不会比猪传染给人的要轻一 些,不是的。这种人传人的猪流感是杂交型的,也就是说,它有3种基因:猪流感、禽流感和人流感混合,在出现猪流感的地区,这种流感的发展方向有可能会变得 明显,迅速地人传人,首先容易威胁青壮年。 

  目前已经有关于猪流感撂倒青壮年的报道。为什么越是体质好,免疫功能旺盛的人,反而容易被猪流感夺命? 

   钟院士解答说:越是年轻体质强壮的人,身体的免疫功能越敏感,发挥的免疫能量就越高。猪流感一旦侵犯这样的人,其人体的免疫细胞,就会迅速释放出来,而 且是因为免疫功能旺盛,一下子释放太多,这些过量释放出来的免疫细胞就产生了自杀效应,破坏人体自身免疫细胞的平衡,出现过度免疫。免疫平衡被破坏之后, 就造成对身体更大的损伤。青壮年一旦被病毒感染,尤其像猪流感这样严重的病毒,自身免疫功能的释放,给身体带来的反作用更大。 

  该如 何防疫?钟院士提出如下建议:密切关注与猪流感传染相关的信息,凡出现猪流感疫情的国家和地区不要去;与猪流感病毒传染疑似的人不要接触。比如目前的国际 体育项目,出现疫情的国家和地区,就有参赛国提出退出。其次就是尽量避免逗留人流稠密,通风条件差的场所,所处环境需空气流通良好。注意个人卫生,必须勤 洗手。出现流感症状,特别是来势汹汹的流感症状,一定要马上就医。</td></tr></tbody></table>
