Corona Virus in perspective

From where did the 2009 'swine-origin' influenza A virus (H1N1) emerge?
The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents.

I’ve read conflicting things about where the first case was identified. Some say Mexico, some say the US, and I’m not sure which ones are using confusing wording. Either way, it’s not all that relevant to my original point, since it was discovered in both countries and Canada within a span of a couple weeks. The travel ban wouldn’t have done any good.

So what? It's here now and we aren't prepared to deal with it.

I went to my barber last evening for a hair cut. they had CNN on the flat screen talking about the travel ban. All of the barbers are of Asian decent. So I said to my barber that we have a saying for things like that:

"Shutting the barn door after the horse got out."

Everyone in the place erupted in laughter. They had never heard that before.

Why would Obama have issued a travel ban? It was first isolated in California and I’m not sure they know where it came from.

"The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents."

So not having travel ban from mexico once it was known - would not help?

Yes, I read your article. However, if you read the first article they cite, it sounds like it was first isolated in the US.

Again, that might be due to ambiguous wording somewhere. I’m now sure.

It strikes me as unlikely since it was already here by then.

but not in the 2009 instance according to the article

"The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents."

then we have

"Six of the genes are closest in sequence to those of H1N2 'triple-reassortant' influenza viruses isolated from pigs in North America around 1999-2000."

from your link

"On April 15 and April 17, 2009, novel swine-origin influenza A (H1N1) virus (S-OIV) was identified in specimens obtained from two epidemiologically unlinked patients in the United States. The same strain of the virus was identified in Mexico, Canada, and elsewhere.

Does not give a date/sequence for the Mexico cases relative to the US ones.
Does not say if Mexico and Canada had it before or after.
"The same strain of the virus was later found in Mexico" might have been a way to sequence it.
Or "first found in human beings on April 15 and 17 2009 " in your article would have been good in establishing that sequence as completely contradicting the first article. But it does not say that.
