Scouter's Ebola Projection Update - 10/4/2014 - (Vanity)

Scouter | 10/4/2014 | Scouter

[scouter]

I have received a number of FReepmails asking for an update on my projections, in light of recent news. Here it is.

Please read and understand the following notes:

1. Because the rate of transmission differs in each country, the model now makes individual projections based on a Daily Transmission Rate (DTR) calculated for each country, and adds them together to produce the numbers presented below.
   
   
2. While the model can use any date range, I've used the the range from 9/1/14 to 10/1/14. In other words, the DTR for each country is based on the number of cases on September 1 vs. the number of cases on October 1. Previous calculations were made based on the rate of transmission from June 1 through August 31.
   
   
3. It appears that the DTR for each country has declined in recent weeks. This is good, but not good enough. The numbers are still scary.
   
   
4. The numbers presented below are based on reported cases and assume that 100% of the actual cases have been reported. We know this is not true. It is somewhat worse than this. Epidemiologists close to the situation believe the actual number of cases is 2-4 times higher. This would have a corresponding effect on the projections.
   
   
5. The model does not yet use a "governor" to limit the number of cases in a given area. In other words, the model projects that in Liberia alone, there would be over 174,000,000 cases by the end of October, 2015. Obviously that can't happen because Liberia doesn't have anywhere near that many people. Future versions of the model will include the "governor function" used by the CDC for this purpose. But according to epidemiologists, the "governor function" wouldn't have a substantial effect on the projections until the projections reach about 50% of the population of the country. So the shorter term projections are more accurate than the longer term. Obviously.

Oh my. Prayers up for food poisoning or something similarly pedestrian.

[onona]

Just for that guy only.

[Ray76]

This could be breaking news!
Hope your wife is ok.

Can you imagine sitting on a plane with some stranger hurling in your midst, worried sick, and the CDC shows up 1.5 hours later in their bunny suits and you’re thinking, “WTH, you get protected while the rest of us sit here wondering if our will is up to date.”

What a horrible predicament, and totally preventable via stopping all movement out of W. Africa.

Does Liberia even have a population of 174 million? Answer: . “Uhmmmm No...”

Uhmmmm... did you even read point #5? Or did you just look at the chart?

[scouter]

What numbers do you predict for the U.S.? Seconded. Please let us know as soon as there is enough ground truth to make a guesstimate meaningful.

I think it will several weeks before we have enough data on the U.S. to be meaningful. But I update my data as new data becomes available. I'm going to leave the U.S. out of it until there has been some actual transmission that occurs here. It's true that we have a diagnosis in the U.S., but it really becomes significant when someone who has never left the U.S. becomes infected.

BTW, I don't predict. I simply project into the future based on past numbers.

Pandemic tourism. They know the welcome carpet is out and they’ll receive free medical treatment courtesy US taxpayers.

It’s the Obola airlift.

[ElenaM]

Not to mention your exposed family being put up in a large house and feted until they show symptoms.

[Jane Long]

TheUnited agent who first reported the Dalles Ebola man’s flight itinerary showed/determined his origination point - final destination. They knew he originated in Monrovia, then traveled to Brussels. Can we not stop passengers who originate in Liberia?

[SaxxonWoods]

If you like your Ebola....

-King Barry

[Veto!]

Praying for the health and safety of your wife and all other passengers and crew.

Do you know which airline?

[txhurl]

Not according to Frieden about 30 minutes ago. Containing ebola only spreads it, he says.

[bgill]

Prayers for your wife.

Please post this in it’s own thread.

[SaxxonWoods]

Being a flight attendant has got to be one of the scariest jobs around all of a sudden...

[ElenaM]

We can but our bureaucratic betters won’t.

[machogirl]

Prayers for you.

[ElenaM]

It’s a United flight, according to local TV.

[Jane Long]

UA 998.

[vetvetdoug]

All it takes is a Jihadi Flight attendant to make Ebola a nightmare for all. Remember Patient Zero for GRIDS was a flight attendant with a grudge to pass the unknown disease he had to anyone willing to have sex with him.

[blueplum]

Your wife’s plane was just shown on Fox news. Prayers up for her safety and health.

It sucks sitting on the tarmack, especially when you know there’s a sick patient on board. They need to deplane these folks into a dedicated hanger so they’re more comfortable.
