A devastating new Politico poll reveals voters believe America has spun off its axis and is “out of control.” 

"An overwhelming majority of voters in the most competitive 2014 elections say it feels as if events in the United States are ‘out of control’ and expressed mounting alarm about terrorism, anxiety about Ebola and harsh skepticism of both political parties only three weeks before the Nov. 4 midterms," reports Politico.

Ebola: What Is The Difference Between Airborne and Aerosolize?

As these terms are bandied around with recent news on Ebola, BAFM found this graphic representation and article courtesy of Sierra12 Defensive Studies Group :

What is the difference between Airborne and Aerosolization when talking about Ebola?

With the recent Ebola events, new talk of the virus being airborne is all over the news .  I wanted to take a moment and talk about airborne or aerosolized pathogens.  Aerosolization is when a particle is small enough and light enough that the particle is suspended in and carried by the air currents.  Aerosolization can be naturally occurring or man made.
A particle or droplet larger than 10 micrometers or 10μm can be transmitted over a short distance of around  2 - 4 meters this would be called -Droplet transmission. 
A particle or droplet smaller than 10μm can be transmitted over longer distance - hundreds of feet depending on environmental conditions, this is called - Airborne transmission.
Keep in mind the sizes above when we talk about transmitting the particle over short distances Vs long distances coming up.
Some common  actions which cause Aerosolization of particles include 
  • Sneezing
  • Coughing
  • Exhaling 
  • Vomiting
  • Speaking
  • Urinating (stream splattering against hard surface)
  • Hand washing
  • Flushing of toilet
  • Brushing teeth

Picture
Since we spoke specifically about Ebola, lets quickly state some of the size characteristics of the Ebola virus.
Ebola virus is approximately 970 nano meters (nm) long and 80nm in diameter.  

I searched and found limited information on the mass of the Ebola virus.  This will be important for our next point.  What I did find established that the mass of a specific Ebola virus being studied was approximately 50 to 60nm in overall size.  That would be approximately 16μm or 16 micrometers.  

1 micrometer or ( 1 μm ) = 1 000 nanometers  or ( 1 000 nm) -reference

You are probably asking why this matter.  The size of the virus matters when we are looking at determining what the particle will do when Aerosolized.  It will also help us better speak using terminology which reflects the current data on the Ebola virus.

t will also help us better speak using terminology which reflects the current data on the Ebola virus.

The CDC has studied Aerosolization and how particles of differing sizes act in still air and in turbulent air.  This is why we need to have a general idea of the overall size of the Ebola virus, by knowing how big it is we can then compare that size to the CDC particle behavior charts.

We are using the proposed overall Ebola size of 16μm for our particle behavior comparison. 

The First chart will depict a particle settling in still air.  Our 16μm particle would have an approximate time to settle of 6 minutes in still air.

The next chart depicts a particle settling in turbulent air.  The same 16μm particle would have an approximate time to settle of 6 minutes in turbulent air.


Below the chart shows particles settling in a closed room with still and turbulent air depicted. 


We see from comparing our proposed 16μm Ebolla virus to the CDC charts above that the approximate settle time for a particle this size in both still and turbulent air would be around 6 minutes.  6 minutes of floating around, not taking into consideration HVAC spreading the particle further than it would have naturally achieved. 

Our proposed Ebolla particle of 16μm would fall in the “over 10μm” particle size and therefore be considered to have a short effective transmission distance of 2 - 4 meters with an airborne time of approximately 6 minutes. Using the term “Airborne” when speaking about Ebolla in my opinion is correct.  when adding in “Airborne” it should also be noted to what extent the particle or virus is “Airborne”.  One might want to cage their classification of “Airborne” with the “short transmission distance” and “time to settle (hang time)” of the virus in the air.

Viability of virus outside host
How long will the virus stay infectious outside a living host?  The time can vary greatly from a few minutes up to 51 days in one case study -reference.  The reason there is so much variation in the viability of the virus is due to environmental considerations.  

Main take away
Stay away from people with Ebola!

Ebola Statistics You May Not Know

The four (4) specialized isolation units in hospitals in the U.S. with the ability to treat Ebola patients include the National Institutes of Health Clinical Center, in Bethesda, Md., a hospital at the University of Nebraska in Omaha, St.Patrick Hospital in Missoula, Mt.,and Emory the University Hospital in Atlanta.

The combined total of beds from these four units is 20 11.

Ebola: Six Reasons to Panic

Here is the recap on why you should be afraid. 

1. It may spread on aerosol particles.
2. It’s infecting almost 2 people for every person that catches the virus.
3. What’s stopping a terrorist from getting Ebola and vomiting in a subway?
4. Worse case computer models show 1,367,000 cases in Libera alone.
5. If the virus leaks out of Libera at this level society will breakdown.
6. Politics will get ugly.

Summary:

(1) Last month, the University of Minnesota’s Center for Infectious Disease Research and Policy published an article arguing that the current Ebola has “unclear modes of transmission” and that “there is scientific and epidemiologic evidence that Ebola virus has the potential to be transmitted via infectious aerosol particles both near and at a distance from infected patients, which means that healthcare workers should be wearing respirators, not facemasks.”

(2) General infection rates are terrifying, too. In epidemiology, you measure the “R0,” or “reproduction number” of a virus; that is, how many new infections each infected person causes. When R0 is greater than 1, the virus is spreading through a population. When it’s below 1, the contamination is receding. In September the World Health Organization’s Ebola Response Team estimated the R0 to be at 1.71 in Guinea and 2.02 in Sierra Leone.

(3) Do you really want to be scared? What’s to stop a jihadist from going to Liberia, getting himself infected, and then flying to New York and riding the subway until he keels over? This is just the biological warfare version of a suicide bomb. Can you imagine the consequences if someone with Ebola vomited in a New York City subway car?

(4) The worst-case scenario envisioned by the model is anywhere from 537,000 to 1,367,000 cases by January. Just in Liberia. With the fever still raging out of control.

(5) And by the way, things could get worse. All of those worst-case projections assume that the virus stays contained in a relatively small area of West Africa, which, with a million people infected, would be highly unlikely. What happens if and when the virus starts leaking out to other parts of the world?

(6) While we’re on the subject of political crisis, it’s worth noting that the politics of Ebola are uncertain and dangerous to everyone involved.

No Clean Hands In Ebola Crisis

Containment should represent the first letter in the CDC acronym.   The world was glad to turn a blind eye when Ebola appeared to be a disease of Africa borne from poverty.  Now, when it’s on the wealthy West’s doorstep, everyone is scrambling.  The U.S. response, because of years of budget cuts to the CDC and education, and most recently  sequestration that closed many research labs, has been inadequate and the U.S. health system has found themselves unprepared.  And now we see, once again, a fragmented policy of catch-up.  Despite what the official line is, the U.S. must do the following:  

1.  Stop all incoming flights and/or travelers from Africa to the U.S. and other countries.  The government argues that this would create an economic crisis.  For whom?  The countries already afflicted seriously with this virus, are in economic disarray.  Closing travel from there to the U.S. will affect approx.135  travelers a day, a negligible economic impact.  Supplies can still be sent to Africa and, in dire circumstances, air dropped.  Aid will continue in order to help bring the epidemic there under control.

2.  Quarantine must be mandatory for all those who are exposed.  It is obvious that half measures such as “monitoring” are not well defined, and as shown in the additional cases in Dallas, ineffective.  Facilities must be identified and equipped to hold potentially infected people in isolation until it can be determined that they do not pose a risk to themselves or others.  Each state should begin now to undertake this effort .

3.  All hospitals and medical personnel must identify several teams to be trained and outfitted as intake personnel to identify, isolate, and deal with immediately any suspected/ infected person.  This may or may not be needed to handle the current crisis, but there are plenty of other viruses and disease that at any time could represent a pandemic threat.

4.  Until more long term solutions are in place, any person once identified should be evacuated from initial health facility to one of the specialized units designated by the CDC to treat Ebola patients.

5.  The head of CDC should assume the duties of a so-called government “Czar” to contain and control our efforts in battling Ebola.  If need be, he or an equally qualified public health epidemiologist or pandemic expert should be empowered to oversee and coordinate U.S. efforts.  Additionally, it may be necessary to hire/appoint additional personnel to handle the other functions of the CDC and provide additional assistance on Ebola.  Creation of another level of bureaucracy with a separate Czar is unnecessary and could lose valuable time in combating the spread of this disease.

In the long run, we must allocate more funds to educate and support science and researchers in the U.S. The health of this nation should not be up to the gamesmanship of politicians as it was during the sequestration. 

The Ebola crisis is also a crisis of poverty and even though the origin  does not  border our country physically, in a global economy there are no borders.  The conditions and standard of living, and issues of wealth disparity should be of concern by the WTO, the U.N.,and member nations just as they are at home..

For this is not the first serious health threat we have faced, nor will it be the last.
