Tamiflu, the Roche Holding AG drug for influenza, can’t fight most infections that have been diagnosed in the U.S. flu season so far, health experts said.
More than half of the flu viruses that have been analyzed in the U.S. this season are of the H1N1 strain, said Joseph Bresee, chief of influenza epidemiology and prevention at the U.S. Centers for Disease Control and Prevention in Atlanta. Virtually all the H1N1 viruses the agency has tested, 72 of 73, are Tamiflu-resistant, he said.
The emergence of Tamiflu-resistant strains that can spread easily from one person to another makes it more difficult for doctors to use drugs to treat people who are at high risk of severe flu complications, such as pneumonia, he said.
Yep, that's evolution. The environment changes (Tamiflu is created) and the species (the H1N1 virus) has to adapt. The members of the species that can change and resist the new threat (Tamiflu) continue on, those who don't die off.
These changes occurred over the time frame of just a few years, imagine the changes that can be seen over millions (hundreds of millions) of years. It is quite simply evolution, the same forces that enabled the virus to change to survive exposure to Tamiflu have, over the eons, created the great diversity of life that we see on out planet.
I am left wondering just how ill-informed or downright dishonest all the evolution deniers are. How can you ignore all the evidence to pretend something so obvious is not occuring?
