We live in a time rapidly changing of the climate and the environment. Some viruses had become the most dangerous nonliving organisms in the world. They are small but their impacts are very deadfall, since most of virus diseases have no cure. However, one type of these dangerous diseases are the emerging viruses, which come by surprise, kill as much people as it can before it goes back to its hibernation. Emerging viral viruses are viruses that contain RNA as their genetic materials, therefore they can quickly adapt to any conditions they live in and that what makes them very dangerous. In addition, RNA viruses in general are dangerous, and the reason behind that is because of their genetic makeup. RNA as known are a single stranded nucleic acid, and it stands for ribonucleic acid, which is a nucleic acid present in all living cells. It's principal's role is …show more content…
During day 10, the person would suffer from vomiting blood, passive behavior, and high fever. During day 11, the person would have bruises, brain damage, external bleeding from the nose, eyes, mouth and anus. During day 12 (the final day), the person would pass out, have seizures, and internal bleeding, and most likely, death. In the other hand, if you do take the vaccine and it is most likely to work, the Africans would not have a major risk of getting Ebola. It would change how the world response to such emerging infectious disease threats, and it will destroy any Ebola virus cells that enters the body. Before it does any harm. According to the article “Fewer Ebola cases so far, this year, but the virus is still a threat”, it states, “The study means that it's ‘less likely than we thought that vaccines and treatment options would fail.’ He said” This shows that it is less likely for the vaccine to not work and the advantages empower the
In 1989, Fogleman et al. analyzed the uncoating and penetration of Simian virus (SV 40). It uses the ganglioside...
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.
But the virus had never been seen outside of Africa and the consequences of Having the virus in a busy suburb of Washington DC is too terrifying to contemplate. Theoretically, an airborne strain of Ebola could emerge and circle. the world in about six weeks. Ebola virus victims usually "crash and bleed," a. military term which literally means the virus attacks every organ of the body. and transforms every part of the body into a digested slime of virus particles.
Like other negative-stranded RNA viruses, the G protein of rabies virus binds to the host cell membranes and penetrates into the host cytoplasm by pinocytosis. The virions are composed of cytoplasmic vesicles, fuse to cytoplasmic membrane and release RNP into the cytoplasm. The core starts primary transcription of the five complementary monocistronic messenger RNAs by using the virion-associated RNA-dependent RNA polymerase. Each mRNA is translated to an individual viral protein. After synthesis and replication of the genomic RNA, the full length, positive-stranded RNA is completed and becomes the template for the next negative-stranded RNA. In the assembly process, the N-P-L complex encapsulates negative-stranded genomic RNA to be made up of RNP core and the M protein consists of a capsule or matrix that su...
In the New York Times interview of Richard Preston, the well renowned author of The Hot Zone, is conducted in order to shed some light on the recent Ebola outbreak and the peaked re-interest in his novel. The Hot Zone is articulated as “thriller like” and “horrifying.” Preston uses similar diction and style choices corresponding with his novel. By choosing to use these specific methods he is advertising and promoting The Hot Zone to the audience members that are interested in reading, and reaching out to those who read and enjoyed his novel. He continuously grabs and keeps the reader’s attention by characterizing and personifying Ebola as the “enemy [and] the invisible monster without a face” in order to give the spectators something to grasp and understand the Ebola virus. Along with characterization, Preston uses descriptions with laminate
Discovery of this virus divided scientist in two groups; the ones in favor of publication the virus and the ones are against the publication. According to Fouchier in the article “The Deadliest Virus” by Micheal Green, he says that if more people have access to it, it
The virus is primarily spherical shaped and roughly 200nm in size, surrounded by a host-cell derived membrane. Its genome is minus-sense single-stranded RNA 16-18 kb in length. It contains matrix protein inside the envelope, hemagglutinin and neuraminidase, fusion protein, nucleocapsid protein, and L and P proteins to form the RNA polymerase. The host-cell receptors on the outside are hemagglutinin and neuraminidase. The virus is allowed to enter the cell when the hemagglutinin/ neuraminidase glycoproteins fuse with the sialic acid on the surface of the host cell, and the capsid enters the cytoplasm. The infected cells express the fusion protein from the virus, and this links the host cells together to create syncitia.
...ving things carry viruses in their cells. Even fungi and bacteria and inhabited by viruses and are occasionally destroyed by them. A virus makes copies of itself in a cell until eventually the cell gets pigged with virus and pops and the viruses spill out of the broken cell. If enough cells are destroyed, such as they do in the case of Ebola, the host dies. A virus does not "want" to kill its host. That is not in the best interest of the virus, because then the virus may also die, unless it can jump fast enough out of the dying host into a new host.
Ebola hemorrhagic fever is a viral disease that was first recorded in 1976, when an outbreak occurred in Yambuku, Zaire, a country that was latter renamed the Democratic Republic of Congo (Walsh, Biek & Real, 2005). During the outbreak 318 cases were recorded of which 280 (88%) died. Later the same year, an outbreak occurred in Sudan where 284 cases were recorded with fatality rate of 53%. The disease and the virus that cause it are named after River Ebola that passes though Yambuku. In the USA, Ebola killed several monkeys in Reston, Virginia in 1989 (Barton, 2006; CDC, 2000). Despite several other outbreaks, the disease has neither medically approved pre-exposure nor post-exposure interventions. However, ongoing research shows optimistic signs.
Viruses are the smallest, simplest living things, smaller than bacteria, and the cause of some of the deadliest diseases known to humanity. They are composed chiefly of nucleic acid wrapped in a coat of protein and are able to multiply only from within living cells. As with all other organisms, the virus depends for its ability to obtain energy and carry out the other processes necessary to sustain life, upon its stock of DNA, the hereditary material that makes up the genes, the "instructions" that determine the traits of every living organism. What is interesting about viruses, however, is that their genetic stock is very meagre indeed, so much so that reliance upon it alone cannot enable them to survive. Nonetheless, viruses do persist from one generation to the next, as if they were alive. How this is managed, as it clearly is in both plants, animals and human beings, bears importantly upon the ways in which "life", at least in the case of viruses, may legitimately b...
Ebola can be spread in a number of ways. Ebola reproduction in infected cells takes about eight hours. Hundreds to thousands of new virus cells are then released during periods of a few hours to a few days. In most outbreaks, transmission from patient to patient within hospitals has been associated within the reuse of needles and syringes. High rates of transmission in outbreaks have occurred from patients to family members who provide nursing care without barriers to prevent exposure to blood, other body fluids such as, vomit, urine and feces. Risk for transmitting the infection appears to be highest during the later stages of illness. Those symptoms include vomiting, diarrhea, shock, and frequently hemorrhaging. Even a person who has recovered from the symptoms of the illness may have the virus present in the genital secretions for a short time after. This makes it possible for the virus to be spread by sexual activity. Complete recovery is reached only when none virus’s cells are left in any body fluids. This is quite rare.
After the death of Charles Monet, the stage is set for much more to come. At the time, Monet’s death was considered unknown, because the Ebola virus was not known about at the time. Medication and antibiotics have no effect on someone with the virus, so obviously it’s pretty serious. Ebola is probably one of the most disgusting things anyone could ever imagine. What is basically does is turn your internal organs into liquid that then pours out of every single hole in your body, even the pores in your skin. Another effect of this virus is coughing up your own blood. This happens because the blood clots in your arteries and veins, which forces it to come out of your mouth and other areas. Eventually your skin will just explode from the pressure of all the blood built up in-between your skin and flesh. This virus can be very deceiving because it has the regular symptoms of diseases like malaria and typhoid fever, but it can kill you within a matter of 10 days.
In 1976 the first two Ebola outbreaks were recorded. In Zaire and western Sudan five hundred and fifty people reported the horrible disease. Of the five hundred and fifty reported three hundred and forty innocent people died. Again in 1995 Ebola reportedly broke out in Zaire, this time infecting over two hundred and killing one hundred and sixty. (Bib4, Musilam, 1)
The writer of the paper cannot agree more with this. Overall, the United States is doing its part in stopping the Ebola virus. West Africa is getting better at dealing with the virus and with our help, they have a chance of eliminating the virus. Technology is improving, treatment for patients is growing, and the world is becoming more aware of the situation. The Ebola virus will be taken down and conquered.
Dengue virus (DENV) is any of the four serotypes that cause the dengue fever or dengue hemorrhagic fever. It is a single positive-stranded RNA virus belonging to the family of Flaviviridae. Its genome is consisted of 11,000 bases that code for three structural proteins, membrane protein M (prM), envelope protein E, capsid protein C, seven nonstructural proteins NS1-NS5, and a short non-coding region on both the 5’ and 3’ ends 2, 6, 19.
