The Ebola Virus

1798 Words8 Pages

Trimester: Trimester 8 Topic: Virology Assignment- Discussion on the problems associated with the sporadic outbreak of Ebola virus and why this current outbreak is posing a serious problem to our health system. Introduction Viruses A virus is defined as a microscopic infectious agent which can only replicate inside the cells of other living organisms. Viruses are generally considered as non-living due to the fact that they are not cells, they do not contain cells and lack living components such as a cell membrane, and they also require a living organism to multiply. Outside of the host, they are classified as non-living. Discovered in 1892 as a strange non-bacterial pathogen infecting tobacco plants (currently identified as tobacco mosaic …show more content…

In certain cases, the virus may not be identified by healthcare workers before contact with bodily fluids is made as there are some diseases with similar initial symptoms to Ebola such as malaria which do not pose a contact threat to healthcare workers. A particular incident would be the case of one Patrick Sawyer, who entered Nigeria on 20th of July 2014 and was an index case (first case) in the Ebola epidemic in Nigeria. He was taken to a private hospital in Nigeria where doctors had not initially identified his condition as Ebola, and had already come into contact with bodily fluids of the infected individual. This problem has caused the mass withdrawal of many healthcare workers and the immediate shutdown of facilities that have been infected. Appropriate methods used to prevent this problem include general awareness and the provision of a containment Bio suit to protect healthcare …show more content…

The most important problem caused by the sporadic outbreak of Ebola virus is that it cannot be anticipated and the appropriate methods cannot be taken until it has begun to progress. This leads to a large death toll as in the current outbreak and a slow reaction time for the general public and healthcare system. Even when the current outbreak subsides, the next major outbreak cannot be predicted and only after the outbreak has begun can proper steps be taken. Working towards the mass manufacture of a vaccine or antiviral treatment or complete cure for the Ebola virus could help solve this problem

TASK 2 Infectious diseases are the invasion of host organisms, (microbes) which can be invisible to the eyes. The microbes are also known as pathogens. A microbe infects an organism (which is known as the host of the microbe). In a human host, the microorganism causes a disease by either disrupting an important body process or by stimulating the immune system to mount a defensive reaction. The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death.

Ebola Virus In The Hot Zone

779 Words | 4 Pages

In response to the Ebola scare in 2014, many people evinced strong fear and xenophobia (Kim, 2016). Especially about the zombie-like symptoms of the virus. In addition how does the virus slowly kills the victim without even realizing that he’s suffering from Ebola virus by replicating and filling the body with crystallized viruses hence damaging the human cells just like a new living organism controls another’s body and killing it bit by bit. To exemplify my relatives used to live in kenya about 43 years ago they were surrounded by ill people that make them terrified and fearful of getting the highly contagious disease, therefore they left kenya and currently they live in the UAE. The most complicated part if you were surrounded by Ebola virus is to calm people down and instead of leaving the country finding beneficial solutions so that the virus won’t disperse from one country to another.

Ebola, despite being discovered in the 1970s, was still mysterious at the time of this big outbreak. The symptoms of Ebola includes internal and external bleeding, vomiting blood, Headache, difficulty breathing, and lack of appetite.

At one point during the outbreak, a deadly strain of Ebola hit Zaire, erupting simultaneously in some 50 villages, killed nine out of ten people it infected. Zaire's president, Mobutu Sese Seko, called out his army to seal the Kinshasa hospital and the entire zone of infected villages, with orders to shoot anyone trying to come out.

The Ebola Virus In The Hot Zone

1948 Words | 8 Pages

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.
