CDC Adopts Near Real-Time Flu Tracking System 102

CWmike writes "The US Centers for Disease Control and Prevention launched an effort this week to better and more easily track for H1N1 and other seasonal influenza activity throughout the US. The CDC said it is now tracking data on 14 million patients from physician practices and hospitals stored on a database hosted by GE Healthcare. The data is submitted daily from physicians' offices and hospitals that use GE's electronic medical record system. The data is then uploaded to GE Healthcare's Medical Quality Improvement Consortium, a database repository designed with HIPAA-compliance parameters of patient anonymity and best practices, where it can be the subject of medical data queries. The CDC can perform queries to look for flu-like symptoms being reported by physicians, and then disseminate the data for health care providers and local government officials throughout the country, who can alert businesses and others about flu outbreak hot spots. The CDC also hopes its analysis of the data helps it better understand the characteristics of H1N1 outbreaks and to determine who is most at risk for developing complications from the virus. Prior to implementing the new system, the CDC relied heavily on tracking insurance claims data, which could take days or weeks to make its way to the agency's medical staff for analysis. The medical data is normalized so that, for example, reports of hypertension, HTN, and high blood pressure all mean the same thing when a researcher enters a query against the data."

    You can find the latest map on the CDC site [cdc.gov] and look at how helpful it is! Apparently everyone's boned except for DC, Georgia, Guam, Hawaii, Puerto Rico and the US Virgin Islands. Since there's no report of flu in the Virgin Islands, I propose the government provides free plane tickets for anyone who isn't infected so that they might escape the wave of vomit brewing in our fair country.

    But in all seriousness their report does have some decent data on it [cdc.gov].

      Uh. Dood. According to the CDC, there was no report of any kind received from the Virgin Islands. That's right, silence! Now what do you suppose *that* means, eh? That's right, EVERYONE in the Virgin Islands has already died from the flu and probably turned into hideous flesh-eating monstrosities!

        Are they correlating this data with the fear of people [slashdot.org] of getting H1N1 in an airplane?

        I recently sent an e-mail to a local radio station after they read a news item stating that, so far this year, 12 people have died from the swine flu in my state. I sent them a letter because that's all that the news item said. It did not mention that about 1600 die of the regular old influenza every year. With all the hysteria about this issue I think some perspective is very badly needed. It's just piss-poor journalism to report a raw figure with no context like this.

        Your comment about the fear of H1N1 made me think about the various ways that it's being encouraged. To me that's just media sensationalism, which is not really unusual because it sells. Is H1N1 a threat to some people? Probably so; I am not a doctor so I should not say too much on that. Do I personally feel threatened by it? Not in the slightest. It'd be a nuisance to me, but not a threat. There's no way I am going to cower in fear and alter my life over it. It is their own damned laziness but the fact is most people aren't going to do their own research on this one. If there were more perspective and context in media reports about H1N1, it would be much easier for others to make up their own minds as I have done.

        Even if this is or were a true threat to life and limb, acting like a bunch of panicked animals is the wrong way to reduce a threat.

I wish some of you would find a different playbook, because these easily-refuted [wikipedia.org] tactics [wikipedia.org] are rather tedious and boring. At any rate, I think that H1N1 has been overhyped and that, speaking only for myself (you want medical advice, talk to a doctor because I am not a doctor) the threat it poses has been greatly exaggerated. That's a conspiracy theory?

As it happens, I was in the middle of making my first serious attempt at writing a novel about a pandemic and all the hysteria it may cause. Of course, now that we're in the middle of one, there's really no point to finishing the book. Having said that, I had researched dozens of reports, information sites from both government and non-government entities, and other things like various states' emergency response plans. It was actually pretty cool having the various states' plans open while "following along" through live streaming on the net. Then someone wrote a post somewhere that aggravated me to my core. He wrote, "call me when there are 36,000 dead because that's how many die every year."

            What his, and apparently your, thoughts about this don't take into account is that we may pass the typical number of fatalities on a single day as the body count rises from say, 28,000 to 42,000. In that hypothetical situation, you and that guy are ready to start caring. What are you going to do the next day when the count climbs from 42,000 to 60,000? At what point do you shit yourself? I watched a symposium on pandemic flu given by the NIH as part of my research, and I learned an interesting fact. During the 1918 Spanish flu outbreak, approximately 4,500 people died in the City of Philadelphia during the course of *one week*.

            Yet you two don't want to do anything until the death toll passes the normal annual figure. Please don't take my word for it. Do your own research. Spend just a little bit of time reading up on the topic. Think about the logistics, and hopefully you will form an opinion that you feel is well-informed and is something you can defend. But just turning your back and calling it scaremongering is irresponsible and dangerous. A lot of people are going to die during the second wave. If we wait until you suggest before taking action, it will be way too late.

      In the UK you're banned from entering your doctor's surgery with flu-like symptoms. You get redirected to the NHS's Pandemic self-diagnosis expert system, which asks you about 10 questions (of which the important one is "do you have more than 2 of the following symptoms: fever, headache, nausea" etc). At the end it spits out a unique reference number for your flu-buddy to go and pickup your prescription of Tamiflu from a chemists. That's it. I did it last week for my partner - she's fine now.
      The thing is, this will lead to overprescribing, and also is probably likely to encourage people to self certify themselves ill when they aren't - so they can have a week off work (no sicknote required for Swine Flu, as you can't get in to see your doctor) and get their supply of Tamiflu in before stocks run out...

      Of course, the fact that this overestimates the reported occurence of H1N1 by a factor of 5 to 50 times [cbsnews.com] is of no concern to us peasants.

      This is actually a reasonably diagnosis.

      From statistical sampling of the population (with strain typing) that's been done so far, the normal seasonal flu strains are not really circulating yet, while H1N1 has been observed to be spiking in frequency. I think there's some diagnosis guideline out there that your family doctor should assume any flu case is H1N1, at this time of the year.

    • Right now, something like 1% of all flu in the US that is attempted to be subtyped is NOT H1N1. See http://www.cdc.gov/flu/weekly/ So basically, if the person has the flu, it is almost definitely H1N1.

    • There's a chart. In summary:

      * If you don't have a fever or body aches or chills or a headache, you have a cold.
      * If you have a runny nose and are slightly tired, and sneezing or a sore throat, and a slow onset of a few days, you have the normal flu.
      * If it shows up over 3-6 hours, with chills, severe aches, headache, and a fever, it's swine flu.

      They're really quite different. No test is needed for most cases...

      The CDC states that only a PCR test can distinguish between seasonal flu and H1N1,
      PCR tests cost between 100 to 300 dollars and takes about 2 days. ( the costs in India were said to be about 200 dollars.
      The PCR machines are expensive; from 50,000 to 100,000 dollars.

      They can only do so many tests ia a day

      I know 2 people who are dead from H1N1 and know 1 person who knew someone who dies. All healthy. 2 were reported with minor symptoms, then suddenly they got bad and died.

      To be expected when you have a nasty flu mov

    Real time flu tracking, eh? Let's all sneeze at once and see if we can crash it.
  • There's already a "near realtime flu tracking system." It's called Twitter.
  • so where are the pretty graphics? Say a map of the US with color codng for hotspots?

  • Reading CDC's website, it's quite interesting to see that according to them 36,000 people on average die from seasonal flu and that's during the flu season. H1N1 only caused what, roughly 500-600 deaths since begining of the year and according to them it's active the whole year. http://www.cdc.gov/flu/about/disease/us_flu-related_deaths.htm [cdc.gov] Hmm, is anyone else getting flashbacks to Wag the Dog? No?
    • Remember the 36,000 is in a vaccinated populas.

      The swine flu has only been going since April, not the beginning of the year.
      It is hitting a different demographic.
      More children died from August to October from swine flu then die all year from season flu.
      This has happend off flu season.
      We are entering flu seaon with almost no vaccinated population
      It's a pandemic.

  • I'm sure that there are lots of studies from manufacturers of hand cleaners and other potions that there products kill xx% of flue viruses. I know I'm being bombarded by directions all the way from my HR department to the CDC on how to prevent getting swine flu. While I'm sure that some of those narrow studies are correct that lots of alcohol will kill the virus, does any of this really make any difference with preventing transmission of the flu. There are lots of assumptions built into suggestions that

      Yes. As does washing with soap and water preferably in warm water.

      ". There are lots of assumptions "
      no there aren't.

      ". Are there any real world population studies to see if this makes any difference?"
      many. We know they coughins is one of the best ways to transmit colds a flues. We know that touching somene is a great way to spread colds and flu. We know very few people shake elbows.

      We also know the N95 masks do almost nothi
