New Study Finds Flu Virus "Paralyzes" Immune System 84
mmmscience writes with this excerpt from Examiner.com: "A study coming out of Children's Hospital of Philadelphia, Pennsylvania, has found that the influenza virus manages to dysregulate the immune system, allowing other infections to thrive in the body. This discovery, coming at an opportune time as the world battles the new H1N1 flu outbreak, may be the first step in understanding why the flu can cause such high mortality rates in normally healthy individuals."

I would guess that it's more coincidence than symbiosis. Most of the things that an influenza virus would find helpful would also be helpful to, say, Streptococcus pneumoniae. Since most infectious organisms are vulnerable to similar immune system defenses, shutting them down just sort of accidentally helps out everyone.
But you could make the argument that these organisms evolved similarities to take advantage of just such strategies. Chicken or egg and all that.

Apparently, Ronnie Michael Smith at the Foundation for Studying Flu discovered this - it's called Glandular Proto-immune Limitation syndrome. Swine Flu is the third variant to be discovered so far, and by far the most pernicious, because it is immune to usual antivirals. It causes most fatailities among those of employable age but who get only limited excercise, with crippling consequences for businesses that do not take extreme measures to exclude it from their buildings.

Mortality rates and the flu (Score:5, Informative)
They speak generally about "the flu", but then use the extreme outliers of the Spanish flu of 1918, and the worst fears of the H1N1 virus, as their examples.
My understanding was that the flu virus hits the immuno-compromised much harder -- the young and the elderly being the most at risk, with it being a day or two off work for people with normal immune systems.
H1N1 is getting a lot of attention primarily because it was outside of the norm for the flu, hitting healthy individuals hard in Mexico, although not repeating that behaviour elsewhere.

Instead of vaccinating or using Anti-Virals (like Tamiflu) is there a way to suppress the Cytokine storm in young adults? I'm not for using immuno-suppressants if that is what it needs but I'm suggesting to inhibit such a reaction (Cytokine Storm) over the short period of time that the flu lasts?
Alternative Explanations from CDC (Score:2)
If you look at the CDC Research [cdc.gov], the major cause of death wasn't actually cytokine storms, but secondary bacterial infections, such as pneumonia, which could be extra-fatal because the immune system was busy dealing with the flu. These days, we have antibiotics which can actually treat those bacterial infections, and there are also vaccines for pneumonia which may be helpful.
Also, another major reason that so many young healthy people died was because the propagation vector was US soldiers returning from W

Actually the problem with the 1918 flu virus was that it had unusually high mortality rates for people with strong immune systems.
The reasoning was that a lot of people died not from the infection itself, but from an *excessive immune response* (cytokine storm).
The whole swine flu paranoia is getting out of hand, especially since so far the actual severity of the swine flu is nowhere near what people are making it out to be. I now have to eat offsite at work because all of the food that I like to eat has been pulled from the cafeteria (all self-serve foods have been pulled except prepackaged items, I almost always eat a build-your-own sandwich and a cookie).
Funny thing is, as a Type I diabetic, who is at unusually high risk for problems if I catch influenza, I'm far more worried about the health effects of this damn menu change than the possibility I might catch H1N1.

Constant vomiting is not likely to be caused by an influenza virus. People call a lot of different things a "stomach flu" but that's really a misnomer. It has nothing to do with influenza.

The latter is not only an accurate accounting of the result, it doesn't overgeneralize the implications. The mechanism studied is only part of the highly complex immune system. The results do not suggest, as does the headline, that the entire immune system gets hosed.

Most flu vaccination is at best a break-even business for drug companies, as are most childhood vaccines.
