...global network of flu experts began to take a good look at the genetic structure of the H1N1 virus, there were indications that the bug might turn out to be little more dangerous than an average flu. Though scientists can't say exactly what genes make a particular strain of flu unusually deadly, all of the viruses that triggered pandemics over the past century - the catastrophic 1918 flu, but also the 1957 and 1968 pandemics - had a particular mutation in the gene that makes a protein called PB1-F2. The H1N1 virus also seems to lack mutations that make...
...Australia, it could cause real damage. And there are still open mysteries, like why the bulk of the infections in the U.S. - and the confirmed deaths thus far in Mexico - have been found in people who are relatively young, which is unusual for the flu, or why this strain seems to be spreading at a time of year when the flu usually levels off. "These viruses mutate, these viruses change, these viruses can further reassort with other genetic material," said Michael Ryan, the WHO's global alert and response director. "So it would be imprudent at this point to take...
...same time, Mexican media outlets have begun to question whether health officials moved quickly enough at the end of March and the beginning of April, when strange flu cases began emerging, to get the strain identified. (See the 5 things you need to know about swine...
...illness for hundreds of other patients showing up in Mexican clinics and hospitals, was A/H1N1. Lezana concedes that Mexican labs did not then have the rare and expensive form of PCR and RT-PCR analysis - a means of identifying a virus' genetic makeup - to pinpoint such an unusual strain. (They have such analysis...
...cooking, so there’s no danger in eating cooked meat of a pig that was sick before it died. The Feds have tried to explain this to Americans and have even started calling the virus “H1N1” (after the scientific name for its strain) to protect industry, but the damage has already been done...
