  1. 1) Droplet transmission was always acknowledged for Ebola going back years, even on the CDC’s FAQ pages, long before this became a news item.
    It’s just that Tom Frieden didn’t read his own agency’s info handouts, and the hairdos at the networks, or anyone at the White House, demonstrably can’t read at all.

    2) The online course is looking at sneezed droplets.
    Unfortunately, projectile vomiting and explosive diarrhea, both typical of mid-course Ebola patients, tend to spew and splatter one helluva lot farther than 1 meter.
    20 feet is average distance, not even world-class travel under those circumstances.
    Ask me how I know this in a deeply personal and experiential way.

    • Hey Aesop,
      Thanks for your work on this so far.
      It looks like the difference between droplet and airborne communication is a semantic one dependent on droplet size, and that the viscosity and sheer volume of the fluids Ebola patients are spewing are the limiting factor.
      As far-fetched as it may sound, couldn’t said fluids be diluted with water and mechanically aerosolized for low-tech weaponization? I’m not promoting the idea, but it seems like if I was of the ‘jihadi already willing to blow myself up’ bent, a backpack sprayer in a shopping mall parking lot could go a long way.

      • I don’t know, only because water isn’t the same as saliva.
        But if a carrier fluid could be found that wasn’t hostile to the virus, that’s exactly one good way you could aerosolize it for bioweapon delivery.

        But you wouldn’t do it in the parking lot.
        You’d mist it over the mezzanine onto the unsuspecting below, and do the same thing at sports venues.

        You could even put it in a mister like one I have for water spray during hot summertime weather, and put on a scaffolding over a busy NY sidewalk, and random-spray hundreds, which would effectively take out NYC for all practical purposes in about a two weeks, when the cases stated showing up.

        The key is if you could concentrate the virus, and find a virus-friendly and very low viscosity carrying-fluid medium, and then put the two together without killing your development staff. That’s the sort of thing biowar experts live for.

        Whether Achmed could manage it is an open question, but they’re definitely getting an eye-opening look at our current pants-around-our-ankles vulnerabilities to any similar attack right now.

        • No need to concentrate, the virus does a nice job for us. In late stages it reaches billions of copies per ml; centrifuge off plasma from a dying patient and you’ve got all you need.
          Most jet style nebulizers from any ER will give you the right particle size spread.
          The LD50 for humans is not known; in the development of a mouse model the LD 50 was one (1) virus:
          http://jid.oxfordjournals.org/content/178/3/651.short
          which is rather impressive.
          And if that isn’t enough, the CDC posts a helpful guide on its website, and if you are willing to perform the heavy lifting of clicking on the link, they show you an experimental article in which they nebulized ebola particles in a breathing hood and infected monkeys. The article is (thankfully) free to view, full-text, on pubmed:
          http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1997182/
          where they go into substantial detail on the nebulizer, the carrier medium, the average size of the particles, & etc. Here it took about 400 viruses to do the job–that is, killing the monkeys in 4-5 days.
          So, I’d argue that if Achmed has some grasp on basic English, this should be well within his capacity.

          • {switching to Devil’s Advocate Sick & Twisted Brain}
            Right, but plasma:
            a) is viscous, thus nebulizes poorly
            b) doesn’t travel or age well outside of ideal storage (refrigerated)
            c) but is a perfect transport and sustainment medium.

            Achmed (Yuri, Wang, Sum Dum Gai, etc.) wants something that will spray like water, stable at room temp, and will sustain, or at least not kill, the payload.

            Plasma thinned with sterile Normal Saline? Ideal, for the 6-12 hours after mixing, and you could spray it from anything onto anything.
            Assuming the virus-laden plasma was refrigerated until mixing, and you mixed it in and loaded the sprayer inside a sealed sterile glove box, sealed it inside, and deconed the outside carrier bottle, you’ve got a biological grenade that’ll kill pretty much everyone it slimes, and then start creating second-order infections 2-21 days after that.
            One rattle-can sized load over the mall food court, and you could create a delayed Ebola cluster that would cripple a city. Do it times 50 on the same weekend, and you’ve just created IRL the basic plot of Tom Clancy’s Executive Orders, from 1996, 18 years ago.
            And shut down the US inside a week.
            (The same guy who described using an airliner as a not-so-smart-bomb in the preceding book, Debt Of Honor, in 1994.)

            • Thanks, Aesop and Doc. I’m sorry I asked.

            • Or you could stuff those missing 11 airliners that were at Tripoli a few months ago full of Ebola carriers and chunk them out over cities….

              • Epic waste, I suspect. Unless you pushed them out the door over the stands at a football game, in which case you might as well just drop sandbags or bricks.

                The whole point of getting them here would be for them to just go walking around town, spreading their pestilence like Johnnie Appleseed planting trees, and no one the wiser.
                11 planes would be an annoyance, and the victims rounded up and put in football stadium isolation. It’d piss folks off, but no major secondary effects. For bio-weapons, that’s pretty much a total fail.

                The way to get this stuff here is just walk it across the Mexican border in a picnic cooler, get picked up for the drive to the safe house(s), mix it up Saturday/Sunday, and head for the mall, the football stadium, the flea market/swap meet, etc. Anything with lots of randomly attending people just milling around. Spray the mist onto people from the upper level at the mall, or the balcony of the movie theatre on a weekend big premiere. No connections to each other, contact-tracing virtually impossible, and liable to come and go from a wide geographic area. Victims start showing up inside a week, get missed initially because “no African contact”; 2-21 days later, they’d infect two-three-four additional tiers of contacts, call it 1K-3K per site. Two weeks in they’d be coming into hospitals puking blood like zombie hordes. We’d never get the genie in the bottle inside of two months, if that, and any city with 20 cases would be a casualty for weeks and weeks.
                And the resultant panic would crash entire time zones.

                Imagine trying to get a hold of everyone who visited Disneyworld or any three Six Flags parks from a given weekend. It would be like asking for everyone who was in Times Square last New year’s Eve to please come in for a chat.

      • Droplet size is critical, it determines how far down in the lung the droplets penetrate. In general, below 5 microns gets all the way to the air sacs of the lungs where they can take up residence in the neighborhood; larger particles tend to get swept up and spit out.

        The distinction between droplet and airborne is based on terminology from publications in the 1940s and is somewhat outdated.
        Ebola is most certainly transmissible by droplet; airborne is anyone’s guess.

        There have been at least 3 proof of principle studies done that demonstrate at least droplet transmission, and maybe airborne. See section on Transmission Studies here:
        http://www.cdc.gov/vhf/ebola/transmission/human-transmission.html#twenty-eight
        But the studies all have flaws that prevent a clear-cut answer.

        Changing mode of transmission in a virus is genetically very, very hard. It is analogous to humans changing their mode of transportation from running on legs to flying with wings. We do this every day, but not because we have sprouted wings–we get in a jet and fly. In a similar fashion, the studies above demonstrate airborne and/or droplet transmission, but used mechanical devices, or specially designed airflow, or alternate organisms (pigs) that generate huge amounts of aerosols, in order to make it work.

        Airborne is tricksy, precious. I am not convinced, but remain convincible.

        Practically speaking, if it is spread by droplet or airborne, it is not the dominant mode of transmission. Not that I hang my unprotected face out in the air for a random ebola-sneeze, mind you, but first things first–you’ve got to deal with the major mode of transmission before you get to the exceptions. And dealing with the extraordinary contact precautions is hard, hard, hard.

        Using the N95 or PAPR hoods definitely protects against droplet. Only the PAPR hoods are clearly effective for airborne.

    • The study noting non-contact infection around a barrier partition in animals is at least from 2012.

      I can see droplets on a 12′ away wall from a good uncovered allergy sneeze. SEE, not detect with microscopy. Observation leads me to believe that only a negative pressure room venting to incinerator with a personnel airlock could allow access without drifting particles leaving a room.

      Quarantine and flamethrowers, investigation and rope.

      Well then that should take care of most of the tax sucking lowlife scurvy murikins and I won’t have to board the family yacht and shove-off to more sterile ground. Thank God for ebola. Let the good times roll.

      • I bet you even have a silk ascot picked out especially for “boarding the family yaht”.
        Darrel Dragon, is that you? The Captain! I understand he was a narcissist, too. Would let Tenille kiss anybody on The Love Boat episodes she was on.

        • Dammit, meant “would not”. Making fun of the self worshipper has got me cracking myself up, cannot type, cannot breathe.

          I wish I had known you in gym class, years ago. We didn’t have sociopaths where I grew up because we used that evil “hazing” ritual to excorcise them. Would have been a pleasure to perform a healing for your betterment.

    I eat fruit and veggies all day long, 2 cloves garlic daily, 6000mg D3, 1000 mg C, 500 E, 1 Centrum multi-vitamin, and 360mg omega 3. Drink only water or juice, and get some type of hard exercise daily. I haven’t been sick 1 day in 5 years. I’m a 51 year young man in perfect health with all my teeth. I fit in around my AO like a round peg in a square hole.

    • Rich! You forgot the part about being rich. And the fact that there’s no one to guard you while you sleep.
      Vanity in men is on the far side of distasteful. Maybe there’s something that correlates between those last two facts, despite the first?
      Hmmm. Please form your rebuttal in mathematical terms.

    • This nutrition and exercise is available at a small effort to everyone who cares. You don’t have to be rich to endure a temporary hunger pang as you bicycle past a dozen greasy FF emporiums offering a $9 meal of diabetes, obesity, plastic agit-prop toys, and lethargy. Not drinking soda/eating c-rap greatly improves oral health, leaving a bunch of surplus cash for dentist visits, ammo, or pre-ordering an imaginary Kel-Tec carbine.

    If I happen to contract it, I imagine I’ll just go on a mailing spree to all the fucktards that allowed this. “Sorry to cough up blood on your letter, Senator, (Mayor/Judge/President/etc.) but you let that Ebola in, and now I have it, so YOU get it too! Congrats asshole!” 😀

    • You surely understand that Your Betters already have some toady screening their incoming.

    • Of course, most of this country’s Only Ones do NOT have screeners. And if any significant number of those Only Ones would have bothered to honor their very oaths of office, we would not be anywhere NEAR where we stand right now. But sending a letter such as you call out will not get very many of them. Instead, why not send them some jelly-filled donuts? Should be able to camouflage the taste with most potential fillings. Let them share a dozen at the station. Of course, the BEST would be to send same to the SS in appreciation of all they have done…

  9. You remember that scene from ‘ No Country For Old Men ‘ ,

    to his head ?
    That is where the average American is right now, and still as

  10. NightWatcher

    I have seen several references to microwave radiation as being an effective method of decontamination for EBOV, but no supporting facts.

    There is evidence that microwaves have NO effect on the virus itself (i.e. genetic or encapsulation disruption). Any damage to the virus is solely related to heat generation. Since microwaves generate heat by exciting water molecules, and the virus itself is somewhat lipophilic/hydrophobic, placing dry articles in the microwave oven for decontamination is suspect at best.

    On the other hand, temperature (140deg F for 30 min) has been shown to completely deactivate the virus. In my mind, a 200 deg oven would work better for mail than a microwave oven.
