Flu season in the Southern Hemisphere is almost over—and now it's heading back our way. At the time this issue went to press, there were more than 162,000 confirmed cases and 1,154 deaths worldwide from "novel H1N1," a.k.a. swine flu, but the Centers for Disease Control and Prevention believes this figure is a gross underestimate, especially since only a fraction of people who have the flu go to the hospital.
Now that the Northern Hemisphere is entering flu season, scientists fear that the virus may come back with a vengeance, compounding the impact of conventional flu, which alone kills about 36,000 people in the U.S. annually. The trouble is that this H1N1 is so genetically different from traditional flu strains that our bodies have few defenses against it and ordinary flu vaccines are useless. What will the virus look like this winter? How rapidly will it spread? How will it mutate? There are too many variables to accurately predict infection rates and death tolls, but our ability to contain the virus hinges heavily on four factors.
Four Keys to Containment
1. Make Vaccines
A vaccine could lower flu risk by 70 to 90 percent—if the virus doesn't evolve into a new strain first. As of press time, the first human trials of a vaccine were beginning in the U.S., and officials are hopeful large quantities will be available this winter. Five pharmaceutical companies are ramping up production under contract from the government. One of those, Novartis, has developed a much faster method for making vaccine, using individual cells instead of chicken eggs, the traditional method. Adapting a virus to grow in eggs can take weeks.
2. Thwart Mutations
Although novel H1N1 virus isn't very deadly now, it's impossible to tell how it will evolve. Mutations in a viral gene that codes for the protein PB2, for example, could increase the virus's ability to replicate and cause more serious illness; that kind of mutation was one of the signatures of the 1918 flu that killed 50 million people. The first hint that such a mutation has occurred might be a big spike in death rates—and that could be too late. The best way to prevent mutations is to control the spread of the epidemic: The fewer people flu infects, the less it evolves.
3. Track Infections
The World Health Organization (WHO) announced in July that this strain of H1N1 is the most rapidly spreading pandemic in history. (Nearly every influenza virus detected in the U.S. last summer was novel H1N1.) And since it's already spread around the globe, the CDC is no longer asking doctors to send swabs from every patient to agency labs for testing. The WHO is relying on people to look for "unexpected, unusual or notable changes in patterns of transmission," like sudden high absenteeism rates at schools or workplaces, or surges in ER visits, and report the events to local agencies. But not having widespread individual testing will make it much harder for researchers to detect new genetic mutations that allow the virus to spread more quickly or evade vaccines as they arise.
4. Medicate Judiciously
Swine flu continues to be sensitive to the antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza). The CDC recommends providing the drugs to those who need it most, like health-care workers and children, but to limit its availability to the general population because the more people who use the drug, the more chances the flu has to develop resistance to it. Tamiflu became virtually useless against the dominant seasonal flu strain in just a year. The other side of the coin: Health-care workers may stop taking antivirals because of the side effects (nausea and vomiting), allowing the infection to spread rapidly throughout hospitals and clinics.
Q. Flu is so common. Why the stink over swine flu?
A. Seasonal flu tends to be genetically similar from year to year, which means that over time, people develop some immunity to it. Novel H1N1, however, is genetically unique; its genes call for proteins with different amino-acid configurations than standard flu. So most of us don't have immunity to it. Strangely, some people over 60 have antibodies against the virus, perhaps because they encountered something similar when they were young.
Q. Why does flu spread faster in the winter?
A. A study published in the Proceedings of the National Academy of Sciences in February showed that the flu virus spreads much better in the drier air and cooler temperatures of winter.
Q. Should I wear a facemask?
A. The CDC only recommends facemasks for anyone at risk of serious illness who is traveling in crowded places or taking care of a sick person, and for anyone already infected who is going out in public.
Q. Should we stop traveling?
A. If you're sick, absolutely. But even if we reduced total human mobility by 60 percent, says mathematician Dirk Brockmann of Northwestern University, we would slow the virus only slightly.
okay, i know a ton of people who are fretting this as if this is some reincarnation of an Biblical Plague, so i have taken it upon myself to do a substantial amount of research and article browsing. I've composed a few key things that i feel are of large importance. these key elements are not so much an instant immunity, but more of a "weapons" upgrade.
obviously, everyone has heard to wash your hands, don't get near infected people, Drink your orange juice for vitamin C, blah , blah, blah. well besides that their is a few other things one can do to.
1) a largely overlooked and very common thing you can do to help your body is to drink Tea, and lots of it! preferably Green or Black tea. Lipton iced tea doesn't count. i personally drink about one or two cups a day everyday year round, but with the rise in this swine flu business i've bumped it up to about four or five cups aday. By this isn't some whack theory that i have, google search swine flu and green tea and you'll see a myriad of articles, but here is an excerpt that pretty much sums them all up.
"Drinking Tea. Immunologists at Harvard University discovered that people who drank five cups of black tea a day for 2 weeks transformed their immune system T cells into “Hulk cells” that pumped out 10 times more cold and flu virus - fighting interferon — proteins that defend against infection — than did the immune systems of those who didn’t drink black tea. Green tea should work just as well. While five cups a day may seem like a lot, Dr. Jack Bukowski of the Harvard Medical School thinks fewer cups may still offer some valuable protection. Moderation is important"
another largely overlooked aspect is the Importance of Vitamin D. Its a statistical fact that nearly 70% of Americans are D deficient. besides being in a few foods in small traces, People get their Vitamin D mainly from the UV rays of the sun. Most people aren't out in the sun all day, and in the winter months its impossible for people living above Tennessee to even get it that based on the angle of the sun. you probably thinking, "yeah.. So what?" well it's being discovered more and more How important VitD is for the Immune system.(Google search it in the news section if your skeptical) But thats Not all. the best part is that Vitamin D is like a 2 for 1 deal. Not only does it Greatly "turbocharge" your overall reaction speed to infections and the effieciency in which it deals with them, but Vitamin D's Anti imflammatory properties. becuase wait for it.. what are most people dying from inconjuction with H1N1? Right you guessed it, Upper respiratory infection. In laymens terms an URI(commonly caused by pneumonia)is when the lungs and what not get congested and then the body's immune system over reacts and Large amounts of inflammation ensues.
The Good thing about all of this is that vitamin D is Fat soluble so you don't constantly loose it. But be advised that a daily Supplement would greatly benefit you this winter season. all in all if you couple the Vitamin D, and some green tea with everything else. you will be a lot better off. Oh and exercise too.
I hope this works for you! Actually there have been decent studies that indicate Vit C does not increase our immunity in any dose. There have been some concern regarding the rush through the trials with the vaccine. Some professionals ie..pharmacists and physicians, are cautious about using this vaccine for their patients. Vaccination, however, is one of the best ways to combat the spread of the virus.
