My kids hate math. Well, at least they tell me they do. With the exception of my seven-year-old (who seems to love math but hasn’t had algebra yet), they insist that they don’t need to know all this “algebra stuff.”
Okay, there is also my four-year-old. She has a firm grasp of the “greater-than/less-than” concept. As long as her stack is greater than your stack, she’s fine.
“C’mon, Dad,” they say, “as long as I can count my money, I don’t need to know any more math.”
Yeah, right. Let’s check back in about twenty years and see how that’s working.
I tease them, “That’s why you’ve got parents; you don’t have sense enough to know what you’ll need beyond dinner.”
The response I usually get is that longsuffering, condescending look that teenagers have that means they’re thinking “Ugh! I can’t wait till I’m eighteen and outta here! I’m gonna change my name and no one will be able to find me.”
I am sympathetic, though. I was young once, long ago, though I probably wasn’t as cool as I remember myself being. I remember that I pretty much hated doing math, too. It always seemed so boring and tedious. I didn’t enjoy the work, and like my kids, I couldn’t see any use for it.
It wasn’t until later in life that I began to appreciate the beauty of mathematics. I started to see that numbers are the building blocks of the universe. Everything physical comes down to numbers.
I’m not going spend much time illustrating this, but an inability to understand numbers hobbles us in life. If we can’t do simple percentages, how do we keep from being overcharged at a 15% off sale? How do we understand an investment prospectus? How do we have even a snowball’s chance of understanding a bill before Congress that will cost tens of billions of dollars and will make sweeping changes in our lives? How can we make the proper choices to keep our loved ones safe in the face of an influenza pandemic?
We can’t.
If we can’t understand and decide these issues for ourselves, someone else will. Eagerly. And without being too concerned about our best interests.
Most of my posts have been, and will continue to be, about the numbers of this pandemic. I am not a mathematician, statistician, or any other “ician.” I do, however, have some experience at working with information like this, and I hope I can communicate well enough to keep your eyes from glazing over. I’ll also give my opinion about this stuff, but don’t just take my word for it and move on. I’ll try to provide enough links to sources so that you can investigate this yourself. There are too many people out there stating conclusions without any supporting evidence, and they expect you to just believe and follow. I don’t want to be like that.
Unfortunately, hard data is difficult to find, and I believe some key information is not being made available to the public. It’s as if someone holding this important data is playing a shell game, constantly moving the shell holding the pea, keeping it mixed up with other shells so we can’t find the right one.
One important piece of this puzzle is the number of infected people. This is key to determining how bad this pandemic may get. I discussed this in The Fog of War, a few weeks ago, and while the public still has not been allowed to see any of the studies that have been done on this, we do have some interesting hints.
Early in the pandemic, the CDC tried to float the idea that somewhere around a million Americans had been infected by swine flu. During this time, the U.S. had been having outbreaks around the country, in many locations. Also during this time, New York City was dealing with an outbreak of its own, and they were dealing with the highly publicized death of an assistant principal of a New York City public school due to H1N1.
So, at the same time that the CDC was trying to claim that a million people in the U.S. had been infected, NYC public health tried to claim half of that total for themselves. That’s right, they claimed that 500,000 New Yorkers had been infected by swine flu.
Both of them couldn’t be right, and in my opinion, they were both wrong.
The CDC later backed away from the one million number, with Dr. Anne Schuchat, CDC spokesperson saying that it was an “estimate” from some statistical models and that the number may be an “overstatement.” NYC public health stood by their 500,000 person estimate. It turns out that they had done some sophisticated telephone work and had called New Yorkers and asked them if they had any flu-like symptoms. Oh, boy.
Later in the summer, Dr. Thomas Freiden, the CDC chief, promised to release studies that had been done to determine the number of infected throughout the country. I’ve not seen any yet.
Oh, by the way, Dr. Freiden began the pandemic heading up New York public health and was later named to run the CDC. Was Dr. Frieden part of that laudable telephone survey? Did he bring that enviable level of strategic thinking to the CDC?
For more discussion of that strategic thinking, see my post We’re Off To See The Wizard.
Today, in large part due to the CDC bungling its mission to reliably inform us about this pandemic, one-half, or more, of Americans say they do not intend to be vaccinated against H1N1. Now, while I think vaccination is a really good idea, I can’t really blame people for thinking that the risk of vaccination is higher than the risk of swine flu. The CDC and almost every other public health department have been playing down the seriousness of this disease for months.
In my opinion, they have been doing this in the hopes that the vaccine will halt the pandemic, like a hero riding in on white horse to save the pretty lady tied to the railroad tracks. Well, much to their dismay, they convinced the lady that the train isn’t coming. To make matters worse, she also thinks the hero looks rather seedy and wants nothing to do with him.
Now, in an effort to get people to be vaccinated, Drs. Frieden and Schuchat and the elite CDC public relations/risk communications team are attempting to convince Americans that this pandemic isn’t mild. It’s like watching Mo, Larry and Curley.
Mo: “Who said it was mild? I never said it was mild.”
Larry: “You said it was serious, then, right?”
Mo: “Who said it was serious? I never said it was serious.”
Curley: “What did you say?”
Mo: “Larry did the talkin’.”
Larry: “I’m not sayin’ nuttin.”
Curley: “So it’s not serious?”
Mo: “It’s less serious than serious.”
Larry: “And more mild than mild.”
While he was NYC Health Commissioner, Dr. Frieden downplayed the virus.
the virus isn’t more virulent than seasonal flu but appeared to be spreading more rapidly than other flu strains. He said the “large clusters” in the schools was “a little surprising.”
Soon thereafter he was moved to the CDC. The Feds know a good one when they see one.
As late as September, Dr. Frieden was saying
“The good news is that so far, everything that we’ve seen, both in this country and abroad, shows that the virus has not changed to become more deadly. That means that although it may affect lots of people, most people will not be severely ill.”
He said this even though dozens of children had already died from swine flu. In fact, by that time we had seen nearly a year’s worth of pediatric flu deaths in a few weeks.
Now, in the face of vaccine resistance, the tune has changed.
On October 6, 2009, Dr. Frieden had this to say about swine flu:
“…despite the clear message from all of us in public health… The first concern that we hear is, oh, flu is just a mild illness. Actually, on average, flu is not a mild illness. It can make you pretty sick, knock you out for a day or two or three. Make you miss school and work. And far too many people end up sending them to the hospital, to the intensive care unit and tragically some people may die from it. In fact, this year already, we have seen quite a few children who have died from flu. So, although it is not a disease that will send lots of people who get it to the hospital, it can be very serious and even for those for whom it’s an average case, it’s no picnic.”
During that same press conference, Dr. Frieden said this in regard to the number infected:
“Even in places where flu has been widespread. It’s affected 5% to 10%. That leads [to] 90% to 95% of the population that’s still susceptible.”
On October 9, 2009, Dr. Schuchat said this in regard to the spring outbreak:
“Even in places that were hard hit with the H1N1 virus last spring, at most, 5% to 10% of people were ill with disease even if many people were infected without having any symptoms. We think the vast majority of people in a given community are vulnerable or susceptible to this virus.”
They have made quite a change in their message. I’m still not sure where the CDC gets their 5-10% infected. Seroprevalence studies? I’ve not seen them. More telephone surveys? Did they just pick a number that fits their message?
Wherever they got it, I have some reason to think that they may, finally, be telling something closer to the truth.
The Alabama Department of Public Health has been publishing, sort of regularly, the results of influenza testing done at the state laboratory. The lab receives samples from various physicians and hospitals from around the state. These specimens are taken from patients that have an Influenza-Like-Illness (ILI). For the week ending September 26, only 56% of the samples sent to the lab were positive for influenza, though only one of the positives wasn’t swine flu. For the next week, 76% were positive for influenza, and all positives were swine flu.
Apparently, a great deal of ILI in Alabama is being caused by something other than flu.
But, there is a lot of ILI activity in the state. The activity reported for last week shows the percentage of visits attributed to ILI continues to be elevated in Alabama (8.1%). The baseline set by CDC defines “significant activity” in Alabama as 2.5%. Based upon this, if we were to take away the proportion of ILI activity associated with positive flu tests, Alabama would still be well above the baseline for significant ILI. A lot of what people think is the flu, isn’t.
See ADPH
One study that I mentioned in The Fog of War seems to support the notion that a significant portion of ILI is not caused by flu. In that study, only 5% of the ILI was caused by influenza.
Another interesting look at this can be found in a guest editorial at Clinical Evidence. The author makes what appears to me to be a good case that influenza causes less than 10% of all ILI and typically infects a very small percentage of the population in given season, perhaps as low as 1%.
So, what does all this mean? Most of us in flublogia have been trying to get a handle on how many people have been infected by the swine flu virus. That number is the first step toward an accurate determination of just how bad this thing is. The CDC, in my opinion, has made no effort to assist the public in finding this out. They have, however, published inaccurate and inflated numbers that would appear to make the swine flu fatality rate less, and therefore diminish the perceived severity of the pandemic.
If, in fact, (1) they are now telling more truth than fantasy, and a lot less people have been infected than earlier estimates, and (2) much of the ILI being reported is not swine flu, and (3) the pressure put on our ICU/ventilator resources in a typical flu season is caused by flu infecting less than 5% of our population, then if we see true attack rate of 20% or more we are in for a really, really bad time.
I invite any discussion or criticism of my reasoning. I would love for someone to convince me that I’m way off base. Feel to comment or to email me at deanb2001@gmail.com.
