Is There a Stronger Mutating H1N1 Virus in Brazil?

It is now reported: Brazil Champion in Swine Flu Deaths

Brazil's Health Ministry informed that 557 people have now died from swine flu in that country surpassing the US in the number of fatal victims of the AH1N1 virus and taking the first place from the United States.

As was reported in Brazil months back, and posted here and here.

The Mutating Virus: A/Sao Paulo/1454/2009(H1N1
Influenza A virus (A/Sao Paulo/1454/2009(H1N1))

The mutating virus from Brazil that the WHO continues to deny is mutating.

That would make the production of the current vaccine, basically useless this fall.

Some scientists have discounted the evidence on the newly found strain that according to scientists in Brazil, is a novel strain.

The CDC under the Obama administration continues to deny that the H1N1 virus has been mutating.

The H1N1 flu strain doesn't appear to be mutating as it makes its way through the Southern Hemisphere, the U.S. Centers for Disease Control and Prevention said today in a briefing.

One of the biggest fears has been that the virus, which first appeared in April in the U.S. and Mexico and which people don't have any built-up immunity to, might mutate into an even more dangerous form. Health officials have been keeping a close watch on the Southern Hemisphere, which is in its winter season now, to see what form of the virus is likely to travel north as fall comes to the U.S. and the rest of the Northern Hemisphere.

What should cause concern is the fact that the H1N1 virus jumped to another host by infecting Turkeys in Chile.

The question should be asked of the CDC and scientists who dispute the fact that the strain has jumped to new hosts and is mutating; why do they continue to deny the fact that the strain is getting stronger as indicated by the rise in deaths in Brazil?
