The Historical Epidemic
The Marburg Virus has been accounted as one of the deadliest viruses on Earth due to its ability to cause high fever and bleeding throughout the body leading to shock and eventually death (Harding, 2014). The epidemic occurred in the late 1960’s when a small group of lab workers from Germany had an outbreak of hemorrhagic fever. The first people who were exposed to the seemed to have some type of contact with green monkeys that were imported from Africa (CDC, 2014). There are animals that are great hosts to the virus but do not show any physical symptoms. One animal in mind is the Rousettus aegyptiacus or the fruit bat. However because of the widely distribution of the bats across Africa there are more possibility for …show more content…

The transmission of the disease is usually human to human interaction, often involving getting in contact with bodily fluids such as blood, secretions and etc. The time period for the infection to show symptoms depending on the individual can take anywhere from two to twenty-one days. Once the virus successfully is in the host and as an optimal environment the symptoms began to take effect it begins rather rapidly (WHO, 2012). The signs start as a high fever followed by a severe headache and extreme discomfort. Over a span of hours or days the intestines are infected resulting in severe watery diarrhea and cramping. The diarrhea can constantly continue for a week. Patients have a blank appearance with baggy eyes and a sluggish motion when they show movement. Between the fifth and seventh day many patients have hemorrhagic manifestations which in fatal cases can cause bleeding in multiple areas in the body. If the virus attacks the central nervous system it can result in confusion and relentless aggression (WHO, …show more content…

The Marburg virus is speculated to attack the endothelial cells in the body causing intravesical coagulation which in terms turns liquid blood into a gel resulting in clots. Endothelial cells are primarily formed in the inner surface of the blood vessel. The cells play a significant role in regulating blood pressure and homeostasis. They form a special selective barrier that has authority on what goes through between the blood and interstitial fluid in tissue (Schnittler et al., 1993).
The disease along with turning liquid blood into gel has the capability to silence the immune system from properly responding to the pathogen. According to Research Associate Shridhar Bale the human immune system usually sound an alarm to the rest of the immune system to properly respond against a virus-specific RNA. However, a protein in the Marburg Virus VP35 binds to the double-stranded RNA and hides to inhibit the alarm. New research shows that the protein circles around the RNA covering it fully. The results is significantly different from the preceding images of the VP35 protein from Ebola virus showing only capping the ends of the RNA but leaving the center of the RNA helix open for detection. (Bale et al.,

In the beginning of The Hot Zone By Richard Preston, readers are introduced to the appearance of a virus similar to Ebola that strikes in western Kenya during 1980 and eventually costs the life of Charles Monet, a Frenchman living by himself. When Monet and his friend travel to the Kitum Cave, he returns to his home and becomes ill on the seventh day. The author then describes Monet’s symptoms and illness in graphic details, providing a sense of terror for the readers. When a doctor named Shem Musoke treats Monet in the Nairobi Hospital, he develops the symptoms of the virus himself. Due to the fact Musoke feels particularly unwell after treating Monet, he is then opened up during an exploratory surgery and his liver appears to be red and

While reading one immediately gets a sense of the harsh symptoms and gruesome death that someone with Marburg would have to endure. A picture becomes painted in the reader’s mind of the horrifying capabilities of the Marburg virus which has the potential to eradicate entire populations. The next few chapters are when the author describes other outbreaks of Ebola which had occurred before Monet had contracted the virus. While describing one of these outbreaks the author, Richard Preston concentrates on one particular story, the story of Nancy Jaax. Nancy was a scientist which had a very close call to almost infecting herself with the virus while examining a sample trying to find the cure for Marburg.

“Plague in Central America,” by Arana Xajila, in the years of 1519-1560 talks about a deadly plague that derives from Europe to Mesoamerica (Central America) and spreads throughout Central America. This plague had spread to the people of Central America when their tribe, Cakchiquels, were fighting against the Spaniards. The Spaniards that were fighting in the tribe had passed on this deadly plague to the Cakchiquels tribe who then passed it on to others in Central America. This plague can be known as the influenza (flu). This deadly virus was spreading rapidly and soon everyone in Central America were affected.

Edgar Allan Poe, writer of "The Masque of the Red Death" could very well be talking about present-day disease, Ebola. In the story, many things send readers' minds straight to the disease and for good reason. Poe could be psychic, or he may simply have a very avid imagination; nonetheless, the similarities are very, very strange. Some of those similarities are the symptoms. One symptom that stands out in my mind as a similarity is the bleeding of the pores.

Rats and the Black Death The Black Death will forever be one of the scariest and catastrophic disease outbreaks that stuck mankind. In 1347 the Black Death surfaced wiping out entire towns, eventually claiming the lives of some 60 percent of the European population. Most of our history teachers and historians blame the outbreak on the fleas carried by the black rat. From my research on the topic I am amazed to say that some of the articles that I have read have me rethinking what I had been taught over this topic may have been wrong or inaccurate.

The virus is introduced to the human population through contact with blood, secretions, organs, and or bodily fluids of the infected animal. The most prevalent cases of Ebola have occurred in Africa, and most strains have been sourced back to the handling of chimpanzees, monkeys, bats, and various other forest animals that had later fallen ill with or were killed by the virus. Once Ebola is contracted from animal to human, an epidemic is an immediate risk. Not only can the disease spread easily from an infected patient during treatment, but even after death, the virus can be spread from the deceased’s body to those handling it, putting funeral-goers at extremely high hazard. The only strain of Ebola that does not appear threatening to humans is the Ebola Reston virus.

Writers from the History webpage claim, “Famous early American Cotton Mather described it as ‘turning yellow then vomiting and bleeding every way.” The only way individuals during the Antebellum era knew that people had been infected was by their symptom, and based upon the symptoms they would experiment until they found a cure. Lastly, Smallpox during the 1990’s was used as a defense mechanism in the

There are diseases today that people caught and spread from certain countries, animals, insects and other people. One example is Ebola. It was discovered in 1976 in Sudan and Yambuku, Democratic Republic of the Congo. Then it reappeared in West Africa in 2014. It started to spread from West Africa and then to other countries like the USA and Nigeria.

The disease is spread through air (coughing, sneezing) or direct contact (skin-to-skin). Symptoms usually include a high fever, continuous sneezing and coughing, and inflamed eyes. These first round of symptoms usually appear one to two week after the disease is contracted. Once the mentioned symptoms develop, a rash emerges three to five days later. There is no treatment for measles, but over-the-counter medications can deaden the symptoms.

Human monkeypox is a viral zoonotic disease caused by the monkeypox virus (MPXV), a member of the genus Orthopoxvirus (family Poxviridae, subfamily Chordopoxvirinae), that occurs mostly in the rain forests of central and western Africa. People living in or near the forested areas may have indirect or low-level exposure, possibly leading to subclinical infection. However, the disease recently emerged in the United States in imported wild rodents from Africa. Monkeypox has a clinical presentation very similar to that of ordinary forms of smallpox, including flulike symptoms, fever, malaise, back pain, headache, and characteristic rash. Given this clinical spectrum, differential diagnosis to rule out smallpox is very important.
