I have a Bachelor’s in Nursing and am currently a graduate student. I have worked extensively with Infectious Disease Specialists. I have been exposed to almost every infectious disease known to the modern world. I have taken courses in Biology, Microbiology, Anatomy, Physiology, Pathophysiology, Advanced Pathophysiology, Pharmacology, and an assortment of others. However, I am not and will not pretend to be an expert, just an experienced professional.
When it comes to an epidemic of any sort, my first focus is on the patient, protecting and healing them, my second focus is on protecting the community. I don’t care about which strain does what, or what we can do with in lab. As a nurse, I concern myself with the current patient and future possible patients. I feel the first thing we should examine is Ebola itself. It is foreign to the US, both literally and figuratively.
What it does to people and how it harmonizes with nature are both things that most westerners have little concept of. It is a virus, not a bacteria. This means that it is not its own organism. It is actually much smaller and basic than you can imagine. It is nothing more than a few pieces of DNA and some proteins. No cell wall, no cytoplasm, no metabolic functions. This is both their advantage and their downfall. Viruses require a host.
For this example I will use the HIV virus. HIV gets into the human body and invades the host’s white blood cells, T4 cells to be exact but I won’t get that involved. The proteins help get the virus into the cell and those few small sequences of DNA write themselves into the host DNA. Now instead of the white blood cell attacking invaders, it is nothing more than an HIV factory. All of its metabolic functions are redirected at producing more of the virus, which pours out of the white blood cell like a sieve until eventually the host cell dies. This is why HIV infected patients have poor immune systems. The virus re-writes the DNA of the host cells.
This is not something we can stop. New viruses are pouring out of the white blood cells at a rate of millions a day. We cannot filter them out. We cannot “kill” a little chunk of DNA and we don’t know enough about the human genome to correct the DNA sequences. This is why a lot of viral infections like HIV, Herpes, and Hepatitis are life long infections.
HIV invades the white blood cells, Herpes invade the nerve roots, and Hepatitis invades the liver.
Now that we have a better grasp of viruses, we will focus on Ebola a bit more. In tropical Africa, Ebola naturally lives in bats. It is nice to the bats and doesn’t cause them many issues. It is rumored that there are many viruses humans carry our entire lives and have no idea because they show zero symptoms.
Therefore, they have never been studied. If this sounds crazy, just remember that it was in recent years the we discovered there was a virus behind cervical cancer. A virus that men can carry and spread without ever knowing they have it. Where the problem arises is that in tropical Africa, people like to eat bats. Sometimes they get infected with Ebola and it spreads.
This process is called Zoonosis and can be true of bacteria or viruses. Canines carry Rabies, Armadillos carry Leprosy, Birds carry the Flu, Bats carry Ebola.
When I said Westerners don’t really understand Ebola, the primary aspect that I am talking about is the patient. We don’t ever see what Ebola does.
Our media is too censored, we hear how many died, and see people in haz-mat suits. Speaking of suits, we’ve all seen the pictures. Rubber gloves are adequate for AIDS and hepatitis, a simple mask stops Tuberculosis, but this requires space suits, just keep that in mind when you think its no big deal. So here is what happens when you catch Ebola, I figure you’re getting bored with reading right about now, so I’ll spice it up. First the virus gets into your system, I’ll elaborate on that later.
Then, it hangs out for a few days, even up to 21, growing, multiplying at a rate of millions a day, and guess what, you’re infectious. Just like with the flu or hand foot and mouth disease, you can be spreading it to others before you show a symptom*. Remember, nurse mind set, protect the community. At first it’s not bad, little nausea, some sweating, diarrhea, much like a stomach bug.
But then the virus really starts to build up in your liver and adrenal glands, after it has saturated your blood cells, the lining of your vessel, your skin, and bones. Hepatocellular necrosis occurs, which is fancy term for your liver starts to decompose.Your liver is what regulates blood clotting. This causes your blood either clot up and turn to jelly in your veins, stay liquid and bleed profusely, or a combo of both. The adrenal glands then do the same, causing your blood pressure to drop. This requires lots of IV fluids to keep your circulating volume up.
At the same time inflammatory cytokines are released which causes vascular leakage. Cells don’t do a good job of holding things together so it all becomes a bloody goop. Anywhere in your body that blood vessels are shallow, like your nose, ears, gums, throat, GI tract, urethra, vagina, rectum, all start oozing fluids and bleeding because the tissues that normally keep it contained are disintegrating. So now you bleed from every orifice, including your eyeballs. Every time someone or something touches you, your tissue gets damaged which further the cycle, so a shot in the arm turn into a massive blood blister. Those who survive are left with massive scarring.
Since the adrenals cannot keep your blood pressure up, and you are losing blood and fluids, we have to put IV fluids in to keep you out of hypovolemic shock. This in turn reduces your blood concentration, lowering your oxygen carrying capacity, which causes your heart to race. So you lay in bed, oozing fluids from everywhere, all while feeling like you just ran a marathon, with bloody diarrhea, oh and did I mention pain? Lots and lots of pain, but you can’t have any pain medicine because your liver and kidneys have failed. This why it pains me when I see this outbreak ONLY has a 50% death rate, when in Africa it is up to 90%…ONLY 50%. That is literally worse than cancer, and people are blowing it off. Imagine if cancer was infectious, and you lived in a country with zero cancer, and someone thought it would be a good idea to fly a few people in. I think there would be a different attitude.
The biggest part of the discussion is how Ebola is spread. I will say two things on the topic, no, it is not airborne, and yes, basic hygiene plays a HUGE factor. But while on the topic of whether it is or is not airborne, the definition of an airborne contagion is one that can freely float in the air, survive lengths of time, and infect someone else. VERY few things fit in this category, most have been eradicated, Polio, Small Pox, Tuberculosis. Things that are also NOT airborne, are the flu and the cold. For the flu, you have to come into direct contact with the patients body fluids. How then, do you explain why people catch it and have no idea how. Well for one, people can spread it before they show symptoms, just like Ebola, and one other HUGE factor…droplets….let that word really sink in.
The virus may not be airborne, but the droplets are. I’m going to digress for a second and get back to HIV and hepatitis, while I let droplets dwell in your mind. Everyone knows that HIV and Hepatitis are spread by blood contact, and sexual fluids, I don’t mean a drop of blood on the skin, or even a mucous membrane, it has to get INSIDE of you. This is why only gloves are required. HIV and hepatitis are not found in urine, stool (Some forms of hepatitis are, but you have to eat the stool to get infected) saliva, sweat, tears, or mucous. This is where some viruses are different. The flu gets into your mucous and other secretions, Ebola tends to stay in the blood, but remember, every one of your bodily fluids are full of blood now. So a person with the flu sneezes, and now millions of little droplets (remember those guys?) shoot out of their nose at nearly mach 1, all across the room, same for a cough, all it takes is a little microscopic droplet to land in your eye, nose, mouth, or the unlikely scenario of an open wound, and you’ve now been infected, because you came in CONTACT with their bodily fluids.
See the word contact thrown around a lot, but most people think of mass amounts of contact with blood, but what they don’t realize is that contact also includes microscopic mucous and saliva droplets, each one chock full of Ebola. Now to the second part of this, HIV only lives outside of the human body for a few seconds, maybe minutes if the quantity is high enough, Hepatitis a bit longer.
That’s why you hear about the dirty needles at movie theaters and playgrounds, but never hear of an infection, before the perpetrator even leaves the theater, the HIV he left in that needle has already died. Ebola on the other hand survives quite well outside of the host, I can’t find my source again, but I believe its up to 4 days.
So with all this information, lets have some role play, so that you can see exactly what this means, to a nurse, in the real world. Imagine it as a cheesy PSA or lifetime movie. You go to see your doctor because its that time of year, you need some blood drawn and refills of your blood pressure med. You sit patiently in the waiting room, thumbing a magazine while your 2-year-old plays with her toys. Like all two year olds, she touches everything, and everything goes in her mouth, toys, pens, her own fingers. She is a 22 lb drool factory and you love her to pieces. You see the doctor, get your goodies, and go home.
A week later your angel starts vomiting blood and within 3 days she dies because her heart raced so fast it finally gave up while trying to maintain a blood pressure. Her eyes are blood red and demonic, her skin falls off in sheets. What you don’t know is that 3 days before your visit, someone thought they had the flu. It is October you see and they sneezed while thumbing through that very same magazine you thumbed through. The same thumb you grabbed her pacifier out of your purse with in the waiting room. The people caring for Ebola patients wear space suits, and burn the bodies, yet it still spreads. Here in America, we have much better protocols, and much better hygiene.
So if it spreads, it will be contained much better. Still, it spreads prior to symptoms and survives will outside the body, just like the flu. Despite vaccines and good hand washing, thousands still get the flu every year. But while the flu kills 1-2% of its victims, Ebola kills 50% on a good day, and spreads the same way. So please, do not write it off as hype. It is a real thing and it is here.
The case in Dallas has been confirmed. The patient had contact with five children and adolescents prior to admission.
Those five kids attend four of the largest schools in Dallas. One sneeze and we could already have thousands of people, who don’t know it yet, infected.
