New Flu Strain Appears In the US and Mexico 315

Combat Wombat writes with this excerpt from Reuters: "A strain of flu never seen before has killed up to 60 people in Mexico and also appeared in the United States, where eight people were infected but recovered, health officials said on Friday. Mexico's government said at least 20 people have died of the flu and it may also be responsible for 40 other deaths. [The government] shut down schools and canceled major public events in Mexico City to try to prevent more deaths in the sprawling, overcrowded capital. ... Close analysis showed the disease is a mixture of swine, human and avian viruses, according to the CDC. Humans can occasionally catch swine flu from pigs but rarely have they been known to pass it on to other people. Mexico reported 1,004 suspected cases of the new virus, including four possible cases in Mexicali on the border with California.

      I would guess that if a serious flu comes through, you will not be able to avoid it.

      However, if I understand correctly, flu typically kills by filling the lungs up with mucus, and preventing breathing -- a fatal pneumonia, if you will. However, such a symptom is entirely (and easily) treatable. The treatment is called PP &D, and it takes about 20 minutes to drain the lungs. In other words, in the time it would take the ambulance to get you and get you to the hospital, you could be in good enough condition to walk out the door.

      I've done this on my kid, and it does greatly improve breathing function.

      Therefore, my advice would be to simply be prepared to do PP & D on others, the price being that they learn to do it, and do PP & D on still others in a 2:1 ratio until the need is gone. That way, if you do get sick, you will have someone to do it on you, and the flu wonâ(TM)t be fatal.

      Here are two good sources on how to to PP&D.
      http://www.phoenixchildrens.com/emily-center/child-health-topics/handouts/CPT-55b.pdf

      http://www.questdiagnostics.com/kbase/as/ug1720/how.htm

      • Speaking from my nursing background here (20+ years as Registered Nurse in Intensive Care, Emergency Room, and medical wards).

        Postural drainage and percussion (PD&P) are appropriate when the "fluid in the lungs" is in the bronchial tree, as in cystic fibrosis and some kinds of bronchitis. It will do no good in pneumonia and may cause greater harm.

        In pneumonia the dangerous fluid is not within the lumens of the bronchial tree where it could be coughed out; it is the walls of the tree that are swollen with excess interstitial fluid that is the danger. The swelling increases the distance between the air sacs and blood vessels, and as it progresses, it collapses the air sacs. So you don't have gobs of stuff blocking the lungs; you've got less working lung area.

        If you start to come down with the flu a good plan would be to avoid exercise or any activity that would increase your O2 demand and your CO2 production. Spend your awake time mostly sitting, and rest in a semi-recumbent position rather than flat in bed. Do deep breathing exercises every half hour or so to help keep airways open. Go with sedentary activities like reading, watching tv, working on improving your slashdot karma, and so on. And remember that the hardware of your mind is now compromised by the illness, so you are not as sharp as usual, your judgment may be bad, and there are going to be more bugs in your code and logic.

    The reason why this strain is so bad is because it's transmissible from person to person with ease.

    On the plus side, it's not resistant to Tamiflu... yet. Given that strains of Tamiflu-resistant human flu are turning up, I wouldn't be surprised to see this one learn to dodge bullets as well.

    That's why this strain is seen as a potential pandemic.

          Unfortunately the difference this time is human to human transmission, which was very limited with the previous examples. The larger question is how much of a mutation has occurred and therefore how potentially dangerous it is.

          Also need to determine how far it has actually spread to get an indication of actually how dangerous it may or may not be - i.e. there's around 8 deaths out of 1004 cases, but if it turns out there's another 1000 unreported cases with no fatalities then it may not be that bad.
      • That's one of the milestones of a really dangerous pandemic

        I'm no infectious disease specialist but after reading the article on the Spanish Flu [wikipedia.org], I don't believe that death of young people is a milestone for a pandemic. Its more a milestone for an extremely deadly virus because thats a sign that its able to subvert or reverse a strong immune system. A pandemic, by definition, is just an infection disease that has a widespread number of cases. It doesn't require the disease to be deadly.

      /sigh. I was hoping to be able to stick with Mac virus jokes but....

      No.

      At this point in the epidemic cycle, that would be a premature panic reaction. Panic always and inevitably causes more harm than good.

      There's a number of factors that influence decision making to limit the spread of any disease. Variables that need to be filled in before far reaching decisions are made include the transmissability and virulence of this particular strain. In other words, things that not yet been established include the number people exposed, the number of people who were exposed who developed symptoms, the number of people who developed symptons that were severe enough to seek medical attention and the number of those who died.

      Some of those, you can make a guess at but you won't know with any reasonable degree of certainty for a while. Meanwhile, the public health system is keeping an eye out for new cases. Between the two, you continue to develop your model, which helps you determine just what the potential is.

      Now, to grossly oversimplify and at the risk of sounding a little callous here, seriously sick people will show up at the hospital, clinic, etc. There's a number of reasons that they might not, but you can bet that if a young adult gets sick of the flu and dies, someone's going to hear about it. With low awareness, this is the group that you catch, which is not okay because there are transmissive people out there wandering around infecting other people.

      The other side of that spectrum is just as bad and in the professional opinion many, can be worse. The moment that the authoritative reaction is severe, such as shutting down transportation systems, the population panics. Suddenly, you have every person with a cough and a runny nose swamping the public health system. Add to the fact that it's now SPRING and the beginning of allergy season in the southern US, and you've just made the difficult job of outbreak investigation and outbreak control much more difficult by several orders of magnitude.

      The response has to be measured in a way to balance numerous factors so NO. Cancelling ar flights at this juncture would be an example of a supremely BAD idea.

      Now, the moment you KNOW that it's spreading faster than you have the capacity to contain and control, THEN you take the drastic step of public alerts limited quarantine. Before then, it's just irresponsible.

    Flu viruses are named after the two main proteins on their surfaces, abbreviated H and N. They are also differentiated by what animal they usually infect. The H in the new virus comes from pigs, but some of its other genes come from bird and human flu viruses, a mixture that the US Centers for Disease Control and Prevention calls "very unusual".

      The problem is that in the absence of more information it could go either way. Mexico City is a great place to infect, if one wants a disease to end up in the US. OTOH, this sort of mixing to my understanding occurs frequently in natural influenza. All it takes is one cell infected simultaneously by two variants of the flu. That in turn just requires one farm simultaneously infected by those two viruses. It sounds like they caught the virus early enough (and it is sufficiently non-lethal) so that they can trace where the disease originated.

In the amount of time it took me to type this paragraph these bugger probably went through a couple hundred generations, and spawned untold mutations. Thats why viruses are so hard to fight. This is especially true with influenza, which is why we don't have a "cure" for it yet.
