Ebola hemorrhagic fever (Ebola HF)

Ebola hemorrhagic pyrexia (Ebola HF) is a severe, and often fatal paint in manhood and in primates that has accure irregularly since its hu furg in 1976. The Ebola computer virus is named after(prenominal) a river in the democratic Republic of the Congo in Africa, where it was front discovered. The virus is thaumaturge of 2 members of the family of RNA viruses c on the wholeed the Filvoridae. There ar quaternion types of the Ebola virus, that but three of the four, pose sickness in humans: Ebola-Z advertisee, Ebola-Sudan and Ebola-Ivory Coast. The fourth, Ebola Reston, only causes disease in primates. The virus is a aim four pathogen (witch is higher than aids) Viral hemorrhagic fevers argon caused by viruses from four families: filoviruses, atomic number 18na viruses, flaviviruses, and bunya viruses. The usual innkeepers for close to of these viruses are rodents or arthropods ( much(prenominal) as ticks and mosquitoes). In some cases, the natural host for t he virus is non known.         Confirmed cases of the virus induct been account in the Democratic Republic, Gabon, Sudan, the Ivory Coast, and Uganda. No case of the deseas has been report in the United States. Some searchers became infect with the virus moreover neer became ill. The manner in which the virus first appears in a human at the start of an outbreak has not been determined, but researchers think that the first someone becomes infect d unitary get hold of with an give animal. Symptoms of the Ebola virus commence four to sixteen age after the person has been septic. The brooding period for the Virus ranges from two to twenty one days. in spite of appearance a week, a embossed rash appears over the holy physical structure; the rash is often Hemorrigic. Hemorrhaging generally occurs from the gastrointestinal tract, causing the long-suffering to turn tail from twain the address and rectum. Beginning symptoms are headaches, breathing pro blems, fevers, red eye, hiccups, chills, br! awn aches, wrong of appetite and shock. As the disease progress, patients experience diarrhea, rash, sore throat, vomiting, and abdominal muscle and chest pain. The patients bring little kidney and liver functions, and have internecine and external bleeding. Their breed does not clot which asshole cause some weighty problems, like causing the capillaries to bleed into border create from raw material. Later symptoms are; eye inflammation, depression, change magnitude genius of pain in the skin, and bleeding from the eyes, ears and nose. The death of a patient occurs.         Diagnosing the Ebola virus in a person who has been infected only a few days is heavy because the early on symptoms, such(prenominal) as red eyes and a skin rash are non-specific to the virus and are seen in new(prenominal) patients with diseases that occur much more frequently. solely if the person has all of the symptoms, and infection with the Ebola virus, are suspected. Researche rs dont picture wherefore some people are able to regenerate from the virus and others are not. It is known that the patients who die usually have not developed a signifi gitt immune response to it at the time of death.         The virus advise easily riddle by dint of several ways. People gutter be exposed to it from dismiss out play with infected origin or secretions. So the virus is often outspread by means of family and friends because they come in such get across with secretions when caring for an infected person. People can in addition get it through contact with objects, such as needles. nosocomial transmition is when the spread of the disease happens within a health safeguard setting, like a clinic or a infirmary. That happens in African health care belongingss when patients are tough without masks, gowns, or gloves. It can also be spread through organs, and semen of an infected person. The virus can be spread through infected needles that ar e reused. In Virginia one of the four viruses had bee! n transmitted from one monkey to another through the air. exclusively Ebola viruses have displayed the magnate to be spread through the air under research conditions, this type of spread has not been hazard among humans in a real world setting. An infected persons vomit or diarrhea, are filled with blood and mucus with the virus in it. Any person that comes in shutdown physical contact with it should be under close surveillance. It can also be spread through sexual contact with an infected person. guess cases should be uninvolved from other patients and exacting barrier breast feeding techniques practised. Recovered patients do not pose a serious threat of infecting another person. But the virus may not be present in a humans body seven weeks after being treated. Even if a patient with Ebola dies, its substantial that direct contact with the body of the deceased patient be prevented.         So far, there is no standard treatment for the Ebola virus. Currentl y, Patients suck in therapy. This consists of balancing the patients fluids and electrolytes, maintaining their oxygen status and blood pressure, and treating them for any complicating infections. Diagnosis requires alter laboratory tests on blood specimens. Handling blood from persons infected with Ebola virus is an extreme biohazard and can be done only in especially equipped laboratories. Testing tissue samples can make diagnosing in patients who have died. Until recently, only three outbreaks of Ebola hemorrhagic fever in humans had been reported. The first two, in 1976 in congou tea and in western Sudan, were monumental outbreaks that resulted in more than 550 cases and 340 deaths. The triad outbreak, in 1979 in Sudan, was smaller, with 34 cases and 22 deaths. In all(prenominal) of these outbreaks, most cases occurred in hospitals where medical checkup supplies were inadequate and where needles and syringes were re-used. separate sick patients in a place requiring the wearing of mask, gown, and gloves; sterilizing needle! s and syringes; and disposing of wastes and corpses in a sanitary way chop-chop softenled the outbreaks.In 1995, an outbreak in Kikwit and surrounding areas in Bandundu Province, Zaire, caused 316 deaths. The outbreak was amplified in a hospital by staff that became infected through poor treat techniques. At the request of health officials in Zaire, medical teams from CDC and the earthly concern Health Organization, and from Belgium, France, and to the south Africa, collaborated to investigate and control the outbreak. Two isolated cases of Ebola hemorrhagic fever were identified in Cote dIvoire in 1994-1995. The most recent outbreaks were in rural Gabon in 1994 and in 1996. A patient from the 1996 Gabon outbreak traveled to Johannesburg, South Africa, and fatally infected a health-worker there as well. The measure of Ebola in Africa presents legion(predicate) challenges, because the location of the natural place the disease comes from is unknown. There are a few established master(a) prevention measures. If the case does appear, scotch condition promote the spread of the virus, health care providers moldiness be able to screw a case of ebola when it appears If you extremity to get a unspoilt essay, order it on our website: OrderEssay.net
