They [the US] have been through that in 2009 with H1N1 and many live thru it, so the new one won't be any different. If it doesn't kill you, it will only makes you stronger.
Let's face it, to contain the virus, it needs the whole world to work together. Sadly, there are many poor or developing countries that cannot fulfill this task due to economic problem and their healthcare system. One country fails, it means the virus will live on, God forbid it mutated, and someday it will find its way to your country no matter what your country has done to contain it. How long your country is willing to do it? a year? 2 years? your country's economy will fail! It will eventually get to you. Our only hope is a validated working vaccine, but as many outbreaks have shown in the past, the vaccine is always late. Maybe this is why the US and EU are reluctant to do anything about it, they let you have it and bet on your body develops the immune system to withstand the virus, wherever they may come from, without scarifying the economy and the cost trying to contain it. To the majority, this is merely a flu, some will have it harsher than the other, but most will survive given the fact that the fatality rate is only 2-3 %. Unfortunately, some people will die. But then again, it will mostly kill the unproductive old people with pre-existing disease, if they die, it will only save your tax money for the healthcare, and so, you see where this is going? Like what they say, life is unkind.
