Evolution of virulence in the ebola virus biology essay
According to a recent figure from the Centers for Disease Control and Prevention CDCthere have been a total of Ebola cases and deaths from Ebola in these three countries The rapid progression of Ebola virus infection has further complicated the control of this disease, affording little opportunity to develop acquired immunity.
Ebola outbreak 2014
Various EBOV outbreaks have fatally infected tens of thousands of chimpan-zees, duikers and gorillas. The Ebola virus is a member of the Filoviridae family. This outbreak also marked the beginning of large-scale real-time molecular epidemiology. Nabel, Author's Reply, Science , It's one billionth our size and it's beating us. Ebola virus and marburvirus are consider to be the most deadly human pathogens that cause severe fever syndrome in both humans and non human parasites. For many survivors of the Ebola disease, this situation would be far too familiar. In the following we illustrate how pathogen sequences produced during the — EVD epidemic provided key insights into EBOV genomic epidemiology and molecular evolution, and note the lessons that need to be learned for the effective study of future outbreaks. As Ebola takes hold of many villages and towns in West Africa, surrounding countries are scrambling to send supplies and aid workers in an attempt to stop the spread of such a lethal virus. In this time the Center for Disease Control spent much time and many resources looking for answers to the many questions they had. Then your organs become liquefied. In addition, a high degree of biohazard containment is required for laboratory studies and clinical analysis. This will be crucially important in our attempts to track and control future infectious disease outbreaks. After this initial spill-over infection, the outbreak remained undetected for several months and spread via chains of sustained human-to-human transmission, with no evidence of additional zoonotic transfers from the animal reservoir 1 — 4.
Ebola was also known as Ebola hemorrhagic fever which is a zoonotic disease caused by direct contact with infected or dead animals "The Natural History of Ebola Virus in Africa. After being infected with the Ebola virus it takes days to take effect.
The encouraging results were published in the journal Science Translational Medicine on June Delgado, L. In the epidemic that followed, a total of 28, confirmed and suspected cases of EVD were documented, with 11, recorded deaths, making it by far the largest outbreak of EVD on record 7. The Ebola virus is one of the most dangerous diseases because it suppresses the immune system, damages the vascular system, leads to multiple organ failure, and hemorrhagic fever along with a chain of various other symptoms.
Altogether, information about Ebola Virus Disease will include: the background, transmission, symptoms and diagnosis, and treatment and prevention. The Ebola virus has been detected in blood and many body fluids, including: saliva, mucus, vomit, feces, sweat, tears, breast milk, urine, semen, and vaginal fluids Willett

Ebola was also known as Ebola hemorrhagic fever which is a zoonotic disease caused by direct contact with infected or dead animals "The Natural History of Ebola Virus in Africa. Methods for detecting the virus have improved drastically. Ebola: EBOV the virus that has captured the attention of viewers worldwide with its recent outbreak. In the United States today, we are not at risk for being infected; however, it is better to be prepared for the worst than to be caught off guard. Thus, sGP may alter the immune response by inhibiting neutrophil activation, while the transmembrane GP may contribute to the hemorrhagic fever symptoms by targeting virus to cells of the reticuloendothelial network and the lining of blood vessels. Xu, R. We provide basic scientists, epidemiologists, medical practitioners, and other outbreak responders with an enhanced understanding of the utility and limitations of pathogen genomic sequencing. These symptoms are then followed by vomiting, diarrhea, rash, and impaired kidney and liver function. Dudley 22 The Ebola Virus is one of the two members of the filovirus family.
