Swine Flu Genetics Suggest a Vaccine Is Possible 116

Kristina at Science News writes "The Centers for Disease Control and Prevention announced findings May 1 from genetic studies of swine flu virus from six different countries. A strong similarity from country to country suggests all the infections are from one strain, making a vaccine a strong possibility. It will be several months at least before such a vaccine would be developed, though."

      Too late for that. Everyone knows it as swine flu... having the media call it something else won't change a thing.

      The real thing that the media needs to be putting straight is just how little of a threat this flu is. It hasn't been any more lethal than seasonal flu, nor is it really spreading as fast as was originally believed.

      The media is causing a panic simply for ratings, which is quite despicable when you think about it.

              We have no idea of the mortality rate of this flu. We don't even have reliable ways of distinguishing it from run-of-the-mill flu on any significant scale. Nobody knows the infection rate.

              In fact this is nothing at all like 1918. That flu killed young, and old alike, and everyone in between. Strong young adults died by the thousands.

      Actually the H1N1 does not mean what you think it means.

      The H stands for Hemagglutanin, a glycoprotein; the N stands for Neuraminidase, a glycosilated enzyme. Both are found on the surface of the virus which can expose them as a good target to use. There are actually other abbreviations referring to different parts of the influenza A RNA based genome.

      H1N1 just indicates the type of Hemagglutanin and Neuraminidase... There are other H1N1 flu viruses as well, like the so called spanish flu which actually originated in the USA. H1N1 doesn't specify a strain originating from pigs and so swine flu might even be a better denomination.

      Only Mexicans seem to die from this influenza strain. The one baby that died in the USA was a Mexican child. Other people don't even get particularly ill from it and it seems to be milder than more common strains of flu. WTF?

      There are only two logical explanations:

      1 - The Mexican flu is a lot more contagious and less lethal than initially thought. Perhaps there are tens of thousands of people in Mexico sick with this flu, with a mortality of less than 1 in 100. In that case there haven't been enough cases outside Mexico for a lot of deaths yet.

      2 - Advanced medical care is keeping critically ill patients in the US alive

      The suggestion that a virus can only kill Mexicans is just retarded.

    • There is as yet no explanation for this.
      There is some speculation but for the moment we cannot say with any confidence why there have been no deaths outside of Mexico.

      It is worth noting that the number of infections outside of Mexico is not yet high enough to provide a reliable statistical sample.

      The sequencing of the complete genome may yield some clues.

    • Most of the deaths so far have been caused not by flu itself, but by secondary infections that are able to invade the body once the flu has weakened the immune system. If you are given antibiotics early on, then this is much, much, less likely to happen. Once the initial scare happened, everyone with flu-like symptoms started rushing to their doctor and was treated correctly. Before then, people just did what you normally do with flu and tried to wait it out.
