US Swine Flu Cases May Have Hit 1 Million

Re: US Swine Flu Cases May Have Hit 1 Million

So you multiplied 25,000 by 400 = 10,000,000. Problem is that you are comparing 12 months worth of seasonal flu to 2 months of new flu.

Lets ignore growth of flu, time of year, etc., you should at least divide by 6 (2mos. vs. 12mos) - that leaves you with less than 2 mil.

Most cases have accumulated in the last month as the new virus exponentially grew, estimate us back to 1 Million.

I can go lower but will stop there.
As posted previously, the math is simple. Population of US is 300 million. About 10% get seasonal flu in a season, or 30 million. CDC confirms 30 thousand or 0,1%. For swine flu, there are over 12,000 listed through last week. It will be about 15,000 in tomorrow's report (through last Saturday) which translates to 15 million so far.
 
Re: US Swine Flu Cases May Have Hit 1 Million

We have all watched the CDC pump these numbers out, 50K - 200K -1 Mil.

My guess is that they are using the 3000 hospitalization figure and the CDC reported low end of the seasonal flu hospitalization rate. 3,000 / .3% is 1,000,000.

However it's a ridiculous overestimate as we don't know what the hospitalization rate is for Swine. High end of season is 1.3 which yields 230,000 cases.

I think swine has a higher hospitalization rate than seasonal and we all know that the actual hospitalization number is at least double the CDC. So let's just guess with 6000 at 2% = 300,000 cases.

300,000 is probably closer to how many are infected.
Your guess is wrong. The CDC uses those who test positive, as determined by their surveillance program that they use for seasonal flu. When someone comes in with flu like symptoms they are tested and the CDC then knows if they have swine H1N1, seasonal H1N1, seasonal H3N2, or influenza B which has NOTHING to do with hospitalizations.

They would have no way to convert hospitalized to infected.

They said over 1 million INFECTED, no hospitalization required.

Here's last week's weekly report (there will be a new one tomorrow).

So based on your advanced model and today's CDC statements....

"the CDC estimates. Half those cases have been in New York City"

You are saying that there is 15m/2 = 7.5 million infected in NYC. Isn't that pretty much the entire population of NYC?

NYC has about 1200 confirmed, but the CDC weekly report is a bit less than the reported confirmed cases (the last CDC report had 12,000 for the entire country, while the number confirmed is over 20,000).

The math is simple if you use the appropriate number. If you don't, you get nonsense numbers like the two that posted (one much too low and the other much too high).
 
Re: US Swine Flu Cases May Have Hit 1 Million

Niman,

I've been through this with you before on the estimate, really nothing new here discussion wise.

Let's agree to disagree. You say 15 Million - I say the CDC estimate is high and there are less than 1 Million.

So if we have been through this before and what I said today was the same as I said previously, why would you take the VERY simple formula (CDC weekly report X 1000) and distort what I said to create an imaginary number that is as absurdly high as yours is absurdly low?
Are we back to the absent students in NYC playing hooky again?

I don't have an official estimate, I was simply playing with numbers for the sake of discussion. My statement that 1 million is to high is simply an assumption based on shaky underlying data. Your 15 million estimate is based on an equally shaky foundation. We are both equally likely to be wrong.

This is a gut feeling argument no matter how many calculations we do. My gut says 1 mil is high, yours says it's "absurdly" low.
 
Re: US Swine Flu Cases May Have Hit 1 Million

I work with kids professionally, so I see between 100-150 people 13-19 years old every day. Two weeks ago, about a quarter of them were hacking and coughing. In 8 years I have never seen that many kids sick in June. Now, out of a particular group of 40-50 I saw, 3 had deep, phlegmy coughs. I think that with the amount of people most of us come into contact with on any given day, it would be hard to see the numbers play out. I saw one report, I think it was New York, that was estimating that about 7% were affected with H1N1, but that means that even in a heavily hit region, you have, roughly speaking, about a 93% chance of not knowing anyone affected. The numbers here are both key and tricky. A tiny percentage of people, constituting a risk we would usually ignore, can wreak havoc if the population in big enough. If just .5% people get this disease badly enough to merit a test, it would be 1.5 million out of work, more than enough to cause an economic disturbance; however, that means 99.5% of the time, you wouldn't know anyone who was a confirmed or even probable case, so it would be really hard to see it affecting any one individual on a personal level, because the other 298.5 million who may be affected won't get tested.
As far as death and hospitalization rates go, Appleblossoms U.S. Death count thread shows that a lot of the fatal H1N1 cases are discovered posthumously.
But even if the numbers were accurate, there are plenty of reasons foe this flu to be scary. If it is only twice as deadly as seasonal flu, not only will an additional 36,000 people die beyond what we would expect normally, but those people will be young adults and children. Young adults are the people we rely on to do a large part of the vital work that keeps society running. If this group dies, orphans will be left behind, work will go undone, the burden to society would be sbstantial, and we would only be talking about a fraction of a percent of the U.S. Population. Numbers are tricky things, and we are missing a lot of info, but I think the case of Adela Chevalier illustrates and underscores a lot of our cause for alarm. Her family and the hospital laid out a clear and disturbing timline: she started showing symptoms Friday, went to the hospital Monday and died Monday night.

So my end thought here is that all of us said something truthful about the pandemic
1. Even if 10 million people have been infected and got sick, the other 290 million Americans, or roughly 97% of the country is still unaffected. The fact that H1N1 has not affected most us personally would be due to the fact that 97% of us would not be directly affected. These figures and anecdotes would then be in agreement and supporting both high numbers of estimated cases and lack of seeing H1N1 first hand. Essentially, it is totally possible you guys are all putting together the pieces of one big puzzle.
2. Even if the number of cases is ten million, there are still plenty of reasons for concern:
A. I have never heard of a healthy 20 year old dying of flu in three days.
B. A summer flu season is still more people dying.
C. The age group most affected is unusual and often tragic.
D. This is just the beginning.
Did you ever hear the story about the three blind men who feel different parts of an elephant? One feels the tail, one feels the trunk, and another the side of the elephant, and when they are asked to report what an elephant, they have wildly different answers, but they are all correct. A pandemic is such a big problem, that seeing every part personally is improbable. The cool part is that on flutrackers, we all get to put contribute our experiences together and get a better look at the phenonema. :) :) :)
 
Re: US Swine Flu Cases May Have Hit 1 Million

LadyThud,

Very well said. All the points you made are the primary reasons why I take notice when I see the CDC throwing these figures at the media. It's an obvious media ploy to convince everyone that swine is mild and ordinary... "nothing to see here".

They are either inflating infection estimates or hiding a ton of hospitalizations.
 
Re: US Swine Flu Cases May Have Hit 1 Million

Lady Thud, great post. I especially like your elephant analogy, very cool and appropriate. For the mass media at least, H1N1 is the elephant in the corner that we would all like to ignore. And I agree with you 100% that the raw numbers don't really convey the alarming nature of the fatalities.
