Abstract Smallpox is a highly infectious disease caused by the Variola virus. This report explores the taxonomic classification, “life cycle”, and mechanism of replication of this pathogen, as well as discusses the virulence and treatment options for an infected human host. This member of the Orthopoxvirus genus is extremely virulent, and has a fatality rate of nearly 30%. While this virus only attacks a human host, similar members of the Voxviridae family produce similar infections in animals.…
Henipavirus or the common name The Hendra Virus was first identified in Australia in 1994 at a racing stable in the Brisbane suburb of Hendra, The Virus originated in Malaysia. The disease is very similar to Nipah Virus which also originating from flying foxes in Malaysia. Signs and symptoms Signs in a human: Symptoms usually develop between 5 to 21 days after contact with an infected horse. These symptoms may include fever,cough,sore throat,headache and tiredness, these are the common symptoms of henra.…
The Norwalk Virus is the most common cause of epidemic nonbacterial gastroenteritis in the world. It is named for the city of Norwalk,Ohio in which the first confirmed outbreak occurred in 1968,infecting almost all the students and teachers of a nearby school. This epidemic, also known as Norovirus, is spherical shaped with hexagonal designs spanning all round its surface. When examined through a microscope,this virus can be in different colors ranging from red and orange to blue and green.…
The virus reacted wild in neural progenitor cells (very early cells that give rise to the bulk of the brain), infecting up to 90 % of cells in a…
This commands the cell to construct new viruses. Once the new viruses mature, they break out of the cell and leave the infected cell dying. Only the infected host cell actually does all the work, the virus only injects its genetic material into its host…
The Tasmanian devil is an apex predator and the largest marsupial carnivore. Devil Facial Tumor Disease (DFTD) is a highly aggressive, transmissible cancer that is decimating the Tasmanian devil population and threatening the species with extinction in as little as thirty years (Brüniche-Olsen et al., 2016). The disease first showed up in 1996 and a second transmissible cancer in devils was discovered in 2014. This disease has since declined the population 95% in some areas while spreading to more than 80% of their range (Hollings, et al., 2014). Research towards a vaccine will help to facilitate the reintroduction of these animals into the wild and would provide a new era in wildlife management and research.…

Medicine, a formerly family affair, has developed in troves since the advent of technology. In the earlier times, it was simply inventions that aided early diagnosis and treatment. New knowledge coupled with new technology has led to many extraordinary and life-saving discoveries and inventions being developed. The idea of creating DNA-coded vaccines, which have been under investigation since the early 1990s, used the advances in technology to specifically target certain structures of diseases and create preventative measures to eradicate previously uncured diseases. As Sandra Galeotti points out in her article about DNA vaccines, The U.S. Food and Drug Administration approved two prophylactic cancer vaccines created by the DNA vaccine process.…
Six year old Estella was ecstatic to hear that she landed the role as Rapunzel in her school’s annual play. She dedicated herself to growing out her blonde hair until it extended down to her hips. During rehearsal, Estella tripped over a small prop, resulting to a small cut which bled excessively and uncontrollably. The very next day Estella combed her hair and noticed numerous strands of her long sleek hair falling out. Her bald spots became visible and she eventually had to shave off all her hair.…
Everyone has probably known someone who has been affected by cancer. Watching someone you love suffer from cancer is a terrible thing. Wishing that there is a cure or a preventative for it is everyone’s dream. It is now a known fact that Cuba has created a vaccine for lung cancer that is called “CimaVax”. This vaccine can help people that are suffering from lung cancer live longer.…
In the movie, Robert is a military doctor who helped create the virus, although it was intended to be a cure for cancer. While the two works discussed above, even with being decades…
Claudia Schimek English l Mrs. Toews October 2015 Deadly Virus Vaccination “I am terrified that Ebola will evaporate from our memories... The availability of a good and safe vaccine would make an immense difference. We are going to see future outbreaks of Ebola,” said Keiji Fukuda, the assistant director general for health security at the World Health Organisation (WHO) (“Ebola Outbreaks Slow”). This virus has been haunting the earth since prehistoric times, and has just recently become active again. Ebola’s background history, how it interacts with the human body and how scientists are trying to come up with a vaccine are probably some of the most recent questions running through scientists’ and researchers’ heads.…
Yes, viruses can cause cancer. In reading chapter 27, viruses contribute to about 15% of all human cancer cases and are capable of altering the human cells they infect. The virus triggers the expression of cancer-causing genes called oncogenes, which causes change in normal function; for example, the light switch always being on. However, virus-induced cancer is extremely difficult to occur because it requires a series of specific events. An examples of virus-induced cancer is the hepatitis B infection and the development of liver cancer.…
(Nationalgeograpics.com 1996-2016) It has altered human history for example the decline in early civilization. Many scientist and health care officials has proven that the life threatening virus no longer exist. In the late 1970’s it waws declared eradicated. Shortly following a successful vaccination test trail that exceed beyond belief, this is formally known as one of the biggest medical breakthroughs in history.…
