Swine Flu Info Blog

My friend has it and he is terrible pain. I want to insure him that it won't happen again. But, I do not want to lie so please answer my question.

I read that the most reported deaths as a result of the swine flu have occurred in people with either severe long-term diseases or impaired immune systems although there is always risk of anyone becoming infected. So does this mean that swine flu is fatal to the elderly and to young children?
Apparently, there have been 141 deaths out of 27,737 cases.

I've heard that if you get infected with the more mild swine flu now, when it mutates and becomes a really dangerous disease, you'll be immune. Is that true?
