did usa was affected by "swine flu"?

Well if I go by your title, then I guess swine flu started from USA and then it spread to to other parts of the world.......in my country till date the confirmed cases of swine fly has reached 98+ it is increasing at an alarming rate........and can get worse if precaution is not taken on time.......

yes, it has made it's way through this country. I suspect there are far more cases than officialy reported because many cases probably go unreported, it simply is not that bad an ilness. I'm pretty sure I came down with it a few weeks ago myself, but was fine after a few days, no meds, no trip to the hospital, etc. This really is being far over hyped.

We were affected just not as bad as some places. We had some schools close here towards the end of the school year.

No you're incorrect. If 1/3 of the world would be infected then every country would have applied military law including a curfew. It is true though that 1/3 of my country is said to be infected if we don't have vaccines ready at the end of the year. I am not worried though, the virus isn't more lethal than a normal flu.
