Yea and the link says absolutely nothing about H1N1 mutating.
Why is all this FUD being allowed on here. Either you have credible supported evidence or don't make sensationalist threads. H1N1 in its current form is bad enough without people flying off the deep end.

Some 478,000 people were registered with national health authorities as suffering from the flu since mid-October, of whom 17 had confirmed cases of swine flu, Lyudmila Mukharska, Ukraine's deputy chief health officer, told a news conference in Kiev.
The nationwide death count from flu-related illnesses since mid-October stood at 86, while 24,000 people have been hospitalized, Mukharska said.
She said the authorities had confirmed that four of the dead had died of the H1N1 virus
Some 148,000 cases have been recorded in the past 24 hours, it added
Minsk. Virus A(H1N1) claimed seventh victim in Belarus, AFP reported. No case with lethal outcome as a result of A(H1N1) flu was registered in the state by the beginning of the month.

The suggestion is clear: the virus was frozen in a laboratory freezer since 1950, and was released, either by intent or accident, in 1977. This possibility has been denied by Chinese and Russian scientists, but remains to this day the only scientifically plausible explanation.

Whenever an organism reproduces, its genes try to make exact copies of themselves. But sometimes mistakes--mutations--occur in this process.
This is true whether the genes belong to people, plants, or viruses. The more advanced the organism, however, the more mechanisms exist to prevent mutations. A person mutates at a much slower rate than bacteria, bacteria mutates at a much slower rate than a virus--and a DNA virus mutates at a much slower rate than an RNA virus.
DNA has a kind of built-in proofreading mechanism to cut down on copying mistakes. RNA has no proofreading mechanism whatsoever, no way to protect against mutation. So viruses that use RNA to carry their genetic information mutate much faster--from 10,000 to 1 million times faster--than any DNA virus.
Different RNA viruses mutate at different rates as well. A few mutate so rapidly that virologists consider them not so much a population of copies of the same virus as what they call a "quasi species" or a "mutant swarm."
These mutant swarms contain trillions and trillions of closely related but different viruses. Even the viruses produced from a single cell will include many different versions of themselves, and the swarm as a whole will routinely contain almost every possible permutation of its genetic code.
Most of these mutations interfere with the functioning of the virus and will either destroy the virus outright or destroy its ability to infect. But other mutations, sometimes in a single base, a single letter, in its genetic code will allow the virus to adapt rapidly to a new situation. It is this adaptability that explains why these quasi species, these mutant swarms, can move rapidly back and forth between different environments and also develop extraordinarily rapid drug resistance. As one investigator has observed, the rapid mutation "confers a certain randomness to the disease processes that accompany RNA [viral] infections."
Influenza is an RNA virus. So is HIV and the coronavirus. And of all RNA viruses, influenza and HIV are among those that mutate the fastest. The influenza virus mutates so fast that 99 percent of the 100,000 to 1 million new viruses that burst out of a cell in the reproduction process (p. 106) are too defective to infect another cell and reproduce again. But that still leaves between 1,000 and 10,000 viruses that can infect another cell.
Both influenza and HIV fit the concept of a quasi species, of a mutant swarm. In both, a drug-resistant mutation can emerge within days. And the influenza virus reproduces rapidly--far faster than HIV. Therefore it adapts rapidly as well, often too rapidly for the immune system to respond.
