Ebola, A Nurse’s Perspective

So a few months ago the country was enthralled with the idea of a few patients, infected with the Ebola virus, coming to the United States. Up until this point, we had been safe from Ebola due to the fact that bats can’t fly over the Atlantic. Some people were completely indifferent, while others had seen Outbreak one too many times. Most were a healthy mix, somewhere in between, but what bothered me the most was both the lack of education and the poor information that was spreading more virulently than the virus could ever hope to.

First, I want to stress that I am a nurse, not a virologist, and hopefully throughout my post you will see that I am not pretending to be one. 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/RNA 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/RNA write themselves into the host DNA/RNA. 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.
