It’s always been a little aggravating to me that most
science reporters or science writers don’t have a science background. There are
a lot of benefits to that, such as their vernacular may not be jargon-heavy, or
they might be able to cover a wide range of topics on a broad, elementary
level. But, there are also a lot of writers that are feeding into the
media-based hysteria to get more clicks. How do you get people to read your
stuff? Scare the crap out of them.
You really can’t escape it. I’ve seen posts on Facebook to
articles that detail inaccurate methods of Ebola transmission (thanks,
“friends”…), and I even heard about it on the radio. Whenever I drive into
work, I usually have the radio on so I can get traffic updates. A week ago, one
of the personalities on a stupid morning show was talking about the isolated
testing for Ebola that was happening in Sacramento (which actually happened for some missionaries, that much is true), and it really made me sad,
because it solidified how little people feel they need to research the stuff
they read online. Everything the deejay said was inaccurate, and all I could think about was the hundreds (thousands maybe?) of people listening at that moment...and believing everything.
But I’m not writing this to call people stupid, or make
anyone feel bad about their news choices. Instead, I’m writing to give you the
facts of what I’ve gathered so far. I’m not on the front lines, and I may not be
a popular blogger or writer for Jezebel or Huffington Post, so I’ll it up to
you whether I’m contributing to they nonsense or not.
So you want to understand Ebola. Where do you start?
If you want to understand the virus itself, you can read some of my previous entries on Ebola.
There are only a few places in the world that are allowed to
research and work with any and all strains of the Ebola virus. For a long time,
that list was limited to only major governmental agencies (CDC, etc.),
especially research agencies that have the capability to work with biosafety level
– 4 (BSL-4) pathogens. You can read more about BSLs here,
but I’ll break it down for you:
- BSL-1: all microorganisms used are not known to consistently cause disease in healthy adults and present minimal potential hazards to lab members and the environment. A good example of this is non-pathogenic E. coli, which is used in almost every lab that has ever existed. Think everything from entry level biology classes to, well, most other labs.
- BSL-2: In addition to being able to work with BSL-1 organisms, BSL-2s can work with organisms that pose a moderate risk or hazard to lab members and the environment. A good example of this is Staphylococcus aureus.
- BSL-3: This is a restricted environment, as the hazards are increased from BSL-1 and BSL-2. The pathogens or organisms researched in these labs can often cause lethal diseases via respiratory transmission, like Mycobacterium tuberculosis which causes tuberculosis.
- BSL-4: Lab work involves microorganisms that are dangerous and exotic, and may or may not have a defined method of transmission yet. This is where Ebola is researcher. Researchers who work with BSL-4 organisms have to change their clothes before entering the clean room, and must shower and decontaminate all materials before leaving the research space. These researchers have to wear full body, pressurized, and air-supplied suits. This is the solitary confinement of pathogen research.

Get it? It’s incredibly dangerous, and you should thank the
researchers that risk their lives to perform the groundbreaking experiments
that they do. If you want to read the follow-up report regarding a researcher
accidentally becoming exposed to Ebola, you can download that here.
Am I at risk of becoming infected?
Unless you are a health care worker who is working with
individuals who are infected and currently experiencing symptoms, your chances
of contracting Ebola are slim to none.
With that being said, the only known method of transmission
for Ebola is direct contact with the bodily fluids of an infected individual. If
you have traveled to Africa recently, and have had contact with someone else’s
bodily fluids, you may want to check in with your doctor. Once someone has recovered
from the virus, they are typically no longer contagious, but the Ebola virus
has been shown to be present in semen for up the 3 months post-infection.
This isn’t like our seasonal flu. Ebola is an incredibly
debilitating infection that can have symptoms including high fever, headaches,
muscle pain, vomiting and diarrhea, and unexpected bleeding or bruising. There have been some really sad stories about churches, mortuaries, and even entire towns banning traditional funeral and burial practices because it puts otherwise healthy people at risk.
Will the outbreak spread to the US?
The CDC has not indicated any potential risks for the
outbreak to spread. Yes, there have been medical professionals and missionaries
that have contracted Ebola during this outbreak, and yes, they have been
brought back to the US for treatment.
BUT, there is a reason for that. Almost all the major
research that has been done to figure out the Ebola virus has been conducted in
the US (or in collaboration with the CDC). Experimental treatments are here,
better medical facilities with isolated rooms and chambers are here.
Let me put
it this way: As of right now, there are 2,615 cases of Ebola between Guinea,
Sierra Leone, Liberia, and Nigeria. There are more than 1 million individuals
who are infected with HIV in the US, and 1 in 6 of them are unaware of their
infection (typically due to negligence with regular testing). HIV is also
spread through direct contact with bodily fluids. But, every time you go into a
hospital, you don’t panic about HIV because medical facilities are prepared to
handle and minimize these types of risks. Take a deep breath and don’t believe
everything Donald Trump says.

OK, I believe you about the risk of getting Ebola in the US,
but I’m still paranoid and want to track it every day.
That’s fine. Check out this amazing website that will give you a detailed update every time something
happens with the outbreak. You can also watch an illustration of the spread of
the outbreak since March 14, 2014.
What about treatments? Why aren’t there treatments?
There are currently 3 companies working on developing
experimental treatments against the Ebola virus: Tekmira, Biocryst
Pharmaceuticals, and Mapp Biopharmaceuticals. All of them are in very early
stages of development, meaning none of them have been approved for use in
humans. ZMapp is the product that is getting the most media because the
experimental monoclonal antibody-based therapy was given to two US patients in
Liberia.
Since this experimental therapy has not been approved, it
requires each patient to consent, and understand the potential risks associated
with experimental, non-approved therapies. Compared to some of the other funded research, Ebola isn't seen as a major threat. Maybe that's because we haven't seen an outbreak this large before, or that it hasn't been a threat to the US yet. Either way, it's getting the attention it needs now to really get some momentum in terms of pushing drug and vaccine development through to (hopefully) a reality.
It is possible for patients to recover and survive an Ebola
infection. In order to do this, the patient needs constant monitoring for fluid
balance, oxygen and blood pressure, and additional treatments for complicating
infections.
This is a lot of information to digest, so I'm going to leave it at that. If you have any other questions that you'd like answered, feel free to let me know!
